Founded in 1850, the University of Sydney is Australia’s 1st university and is regarded as a single of its most prestigious, ranked as the 27th most trustworthy university in the world. In 2013, it was ranked 38th and in the prime .3% in the QS Globe University Rankings. 5 Nobel or Crafoord laureates have been affiliated with the university as graduates and faculty. The University is colloquially identified as one of Australia’s &quotSandstones&quot, a status similar to that of the &quotIvy League&quot in the United States and the &quotRussell Group&quot in the United Kingdom.

The university’s Coat of Arms, granted by the College of Arms are an amalgamation of the arms of the universities of Oxford and Cambridge, and their essential figures, heraldry and other references to the two ancient universities are sprawled throughout the university in its architecture and character. Its motto, &quotSidere mens eadem mutato&quot translated actually gives &quotThough the stars adjust, the thoughts is the very same&quot, but has been a lot more liberally translated to give, &quotSydney University is actually just Oxford or Cambridge laterally displaced around 12,000 miles&quot.

The 2013 QS Planet University Rankings placed Sydney in the leading 20 in the planet in 11 subjects more than a third of the 30 measured. The University of Sydney was ranked 8th in the planet for Education, 9th in Accounting and Finance and 10th in Law. Moreover, Sydney was placed 12th in English Language and Literature, History and Archaeology, Linguistics and Civil Engineering and Structural Engineering, the highest in Australia of these subjects. Psychology at Sydney was ranked 14th, Pharmacy and Pharmacology, and Communication and Media were ranked 16th, and the Sydney Health-related School was ranked 17th.

Its primary campus has been ranked in the prime ten of the world’s most beautiful universities by the British Everyday Telegraph, The Huffington Post and Disney Pixar, among other individuals such as Oxford and Cambridge and is spread across the inner-city suburbs of Camperdown and Darlington.

The analysis and education hub of the Charles Perkins Centre is a 49,500 square metre state-of-the-art building made to help collaboration and new ways of considering. Opened for Semester 1 of 2014, the new developing comprises a structure of six floors, plus 3 basement levels, and an location of approximately 49,500 square metres – almost twice the surface location of the Sydney Cricket Ground.

Located on the north-west boundary of the University’s Camperdown Campus, bordering St John’s College and subsequent to the Royal Prince Alfred Hospital (RPA) – Sydney’s largest hospital and the teaching hospital of the Sydney Medical School. The hub will play a important function in fostering collaboration and multidisciplinary analysis, generating a analysis and education precinct with hyperlinks to nearby affiliated medical analysis institutes and the hospital.

This creating along with the original sandstone Anderson Stuart health-related school is my new property.

These tulips have been opening up to the sun in our garden last spring.

The tulip is a perennial, bulbous plant with showy flowers in the genus Tulipa, of which around 75 wild species are presently accepted and which belongs to the family members Liliaceae.

The genus’s native range extends west to the Iberian Peninsula, by way of North Africa to Greece, the Balkans, Turkey, all through the Levant (Syria, Israel, Palestine, Lebanon, Jordan) and Iran, North to Ukraine, southern Siberia and Mongolia, and east to the Northwest of China. The tulip’s centre of diversity is in the Pamir, Hindu Kush, and Tien Shan mountains. It is a common element of steppe and winter-rain Mediterranean vegetation. A quantity of species and several hybrid cultivars are grown in gardens, as potted plants, or as reduce flowers.

Tulips are spring-blooming perennials that develop from bulbs. Based on the species, tulip plants can be in between four inches (ten cm) and 28 inches (71 cm) high. The tulip’s large flowers usually bloom on scapes with leaves in a rosette at ground level and a single flowering stalk arising from amongst the leaves.Tulip stems have few leaves. Larger species tend to have several leaves. Plants normally have two to six leaves, some species up to 12. The tulip’s leaf is strap-shaped, with a waxy coating, and the leaves are alternately arranged on the stem these fleshy blades are often bluish green in colour. Most tulips make only 1 flower per stem, but a couple of species bear a number of flowers on their scapes (e.g. Tulipa turkestanica). The typically cup or star-shaped tulip flower has 3 petals and 3 sepals, which are often termed tepals due to the fact they are almost identical. These six tepals are frequently marked on the interior surface close to the bases with darker colorings. Tulip flowers come in a wide selection of colors, except pure blue (a number of tulips with &quotblue&quot in the name have a faint violet hue).

The flowers have six distinct, basifixed stamens with filaments shorter than the tepals. Each and every stigma has 3 distinct lobes, and the ovaries are superior, with 3 chambers. The tulip’s seed is a capsule with a leathery covering and an ellipsoid to globe shape. Each capsule includes quite a few flat, disc-shaped seeds in two rows per chamber. These light to dark brown seeds have really thin seed coats and endosperm that does not normally fill the entire seed.

Etymology

The word tulip, first described in western Europe in or around 1554 and seemingly derived from the &quotTurkish Letters&quot of diplomat Ogier Ghiselin de Busbecq, initial appeared in English as tulipa or tulipant, entering the language by way of French: tulipe and its obsolete type tulipan or by way of Contemporary Latin tulīpa, from Ottoman Turkish tülbend (&quotmuslin&quot or &quotgauze&quot), and could be in the end derived from the Persian: دلبند‎ delband (&quotTurban&quot), this name becoming applied simply because of a perceived resemblance of the shape of a tulip flower to that of a turban. This might have been due to a translation error in early instances, when it was trendy in the Ottoman Empire to wear tulips on turbans. The translator possibly confused the flower for the turban.

Tulips are referred to as laleh (from Persian لاله, lâleh) in Persian, Turkish, Arabic, and Bulgarian. In Arabic letters, &quotlaleh&quot is written with the exact same letters as Allah, which is why the flower became a holy symbol. It was also related with the Home of Osman, resulting in tulips being extensively utilized in decorative motifs on tiles, mosques, fabrics, crockery, and so forth. in the Ottoman Empire

Cultivation

Tulip cultivars have typically a number of species in their direct background, but most have been derived from Tulipa suaveolens, usually erroneously listed as Tulipa schrenkii. Tulipa gesneriana is in itself an early hybrid of complicated origin and is most likely not the exact same taxon as was described by Conrad Gesner in the 16th century.

Tulips are indigenous to mountainous locations with temperate climates and require a period of cool dormancy, identified as vernalization. They thrive in climates with extended, cool springs and dry summers. Tulip bulbs imported to warm-winter regions of are often planted in autumn to be treated as annuals.

Tulip bulbs are usually planted around late summer season and fall, in properly-drained soils, typically from 4 to 8 inches (ten to 20 cm) deep, based on the kind. Species tulips are typically planted deeper.

Propagation

Tulips can be propagated by means of bulb offsets, seeds or micropropagation. Offsets and tissue culture methods are indicates of asexual propagation for producing genetic clones of the parent plant, which maintains cultivar genetic integrity. Seeds are most typically employed to propagate species and subspecies or to generate new hybrids. Many tulip species can cross-pollinate with every single other, and when wild tulip populations overlap geographically with other tulip species or subspecies, they typically hybridize and create mixed populations. Most industrial tulip cultivars are complex hybrids, and usually sterile.

Offsets need a year or more of growth ahead of plants are big adequate to flower. Tulips grown from seeds frequently need 5 to eight years just before plants are of flowering size. Industrial growers usually harvest the tulip bulbs in late summer time and grade them into sizes bulbs huge sufficient to flower are sorted and sold, whilst smaller bulbs are sorted into sizes and replanted for sale in the future. The Netherlands are the world’s major producer of commercial tulip plants, generating as many as three billion bulbs annually, the majority for export.

Evidence for Recent Liquid Water on Mars

Image by NASA on The Commons
Description: This image, acquired by the Mars International Surveyor (MGS) Mars Orbiter Camera (MOC) in Might 2000 shows quite a few examples of martian gullies that all start–or head–in a specific layer roughly a hundred meters beneath the surface of Mars. These attributes are situated on the south-facing wall of a trough in the Gorgonum Chaos area, an region identified to have a lot of examples of gullies proposed to have formed by seepage and runoff of liquid water in recent martian occasions. The layer from which the gullies emanate has recessed backward to type an overhang beneath a harder layer of rock. The bigger gullies have formed an alcove–an area above the overhang from which debris has collapsed to leave a dark-toned scar. Under the layer of seepage is located a dark, narrow channel that runs down the slope to an apron of debris. The little, bright, parallel characteristics at the base of the cliff at the center-correct of the picture is a series of large windblown ripples. Though the dark tone of the alcoves and channels in this image is not probably to be the result of wet ground (the contrast in this image has been enhanced), it does suggest that water has seeped out of the ground and moved down the slope very not too long ago. Sharp contrasts in between dark and light places are hard to preserve on Mars for really long periods of time due to the fact dust tends to coat surfaces and minimize brightness differences. To preserve dust from settling on a surface, it has to have undergone some procedure of erosion (wind, landslides, water runoff) comparatively not too long ago. There is no way to know how current this activity was, but educated guesses center among a couple of to tens of years, and it is totally possible that the location shown in this image has water seeping out of the ground right now. Centered close to 37.9S, 170.2W, sunlight illuminates the MOC image from the upper left, north is toward the upper right.

Quoting from Wikipedia | Space Shuttle Enterprise:

The Space Shuttle Enterprise (NASA Orbiter Automobile Designation: OV-101) was the 1st Space Shuttle orbiter. It was built for NASA as part of the Space Shuttle system to execute test flights in the atmosphere. It was constructed without having engines or a functional heat shield, and was consequently not capable of spaceflight.

Originally, Enterprise had been intended to be refitted for orbital flight, which would have produced it the second space shuttle to fly after Columbia. Nevertheless, during the building of Columbia, information of the final design changed, especially with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the nation. As this was an expensive proposition, it was determined to be significantly less pricey to construct Challenger about a physique frame (STA-099) that had been developed as a test post. Similarly, Enterprise was regarded for refit to replace Challenger soon after the latter was destroyed, but Endeavour was built from structural spares as an alternative.

Service

Construction began on the 1st orbiter on June four, 1974. Designated OV-101, it was initially planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A create-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named following the Starship Enterprise, featured on the tv show Star Trek. Although Ford did not mention the campaign, the president—who for the duration of World War II had served on the aircraft carrier USS&nbspMonterey&nbsp(CVL-26) that served with USS&nbspEnterprise&nbsp(CV-six)—said that he was &quotpartial to the name&quot and overrode NASA officials.

The design and style of OV-101 was not the identical as that planned for OV-102, the initial flight model the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A huge quantity of subsystems—ranging from main engines to radar equipment—were not installed on this car, but the capacity to add them in the future was retained. As an alternative of a thermal protection system, its surface was mainly fiberglass.

In mid-1976, the orbiter was employed for ground vibration tests, allowing engineers to examine data from an actual flight car with theoretical models.

On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek had been on hand at the dedication ceremony.

Strategy and landing tests (ALT)

Major report: Strategy and Landing Tests

On January 31, 1977, it was taken by road to Dryden Flight Investigation Center at Edwards Air Force Base, to begin operational testing.

Although at NASA Dryden, Enterprise was used by NASA for a variety of ground and flight tests intended to validate elements of the shuttle plan. The initial nine-month testing period was referred to by the acronym ALT, for &quotApproach and Landing Test&quot. These tests integrated a maiden &quotflight&quot on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking characteristics of the mated system. Ground tests of all orbiter subsystems had been carried out to confirm functionality prior to atmospheric flight.

The mated Enterprise/SCA combination was then subjected to five test flights with Enterprise unmanned and unactivated. The goal of these test flights was to measure the flight characteristics of the mated mixture. These tests were followed with three test flights with Enterprise manned to test the shuttle flight handle systems.

Enterprise underwent 5 free of charge flights where the craft separated from the SCA and was landed below astronaut manage. These tests verified the flight characteristics of the orbiter design and style and were carried out below many aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation difficulties have been revealed, which had to be addressed just before the very first orbital launch occurred.

On August 12, 1977, the space shuttle Enterprise flew on its own for the 1st time.

Preparation for STS-1

Following the ALT plan, Enterprise was ferried among several NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and strong rocket boosters (known as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.

Retirement

With the completion of critical testing, Enterprise was partially disassembled to permit certain components to be reused in other shuttles, then underwent an international tour going to France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (throughout the 1984 Louisiana World Exposition). It was also utilised to match-check the in no way-utilised shuttle launch pad at Vandenberg AFB, California. Finally, on November 18, 1985, Enterprise was ferried to Washington, D.C., where it became house of the Smithsonian Institution.

Post-Challenger

Soon after the Challenger disaster, NASA deemed using Enterprise as a replacement. However refitting the shuttle with all of the needed equipment needed for it to be utilized in space was regarded, but rather it was decided to use spares constructed at the same time as Discovery and Atlantis to develop Endeavour.

Post-Columbia

In 2003, right after the breakup of Columbia for the duration of re-entry, the Columbia Accident Investigation Board carried out tests at Southwest Investigation Institute, which utilized an air gun to shoot foam blocks of equivalent size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing major edge. They removed a fiberglass panel from Enterprise’s wing to perform evaluation of the material and attached it to the test structure, then shot a foam block at it. Although the panel was not broken as a outcome of the test, the influence was adequate to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was 2.five occasions weaker, this recommended that the RCC major edge would have been shattered. Added tests on the fiberglass were canceled in order not to risk damaging the test apparatus, and a panel from Discovery was tested to determine the effects of the foam on a similarly-aged RCC leading edge. On July 7, 2003, a foam effect test designed a hole 41&nbspcm by 42.five&nbspcm (16.1&nbspinches by 16.7&nbspinches) in the protective RCC panel. The tests clearly demonstrated that a foam effect of the kind Columbia sustained could seriously breach the protective RCC panels on the wing leading edge.

The board determined that the probable lead to of the accident was that the foam influence caused a breach of a reinforced carbon-carbon panel along the leading edge of Columbia’s left wing, permitting hot gases generated for the duration of re-entry to enter the wing and lead to structural collapse. This brought on Columbia to spin out of handle, breaking up with the loss of the entire crew.

Museum exhibit

Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport ahead of it was restored and moved to the newly constructed Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection once the Shuttle fleet is retired. When that happens, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the automobile in early 2010 and determined that it was safe to fly on the Shuttle Carrier Aircraft after once more.

Storytellin’

Image by Viewminder
I gotta admit that I truly take pleasure in meetin’ folks and sharin’ excellent stories with them.

Great story tellers often appreciate every single others firm.

I consider I was born to be a sailor.

Because I enjoy the water and sailor’s inform the best stories.

Long hours of tediousness and boredom at sea punctuated by brief periods of indescribable terror and panic develop the ideal atmosphere for telling stories.

Not only that… but in all of that monotony sailors themselves since time started have sat about in circles and passed the ‘story torch.’

I do it on the street all the time.

It usually goes like this…

I meet a person and they inform an interesting story that I appreciate hearing.

Does not matter if the story is great most of the time…

a good story teller is an artist that can render any tale exciting and pull you appropriate into it.

The thing is… and this is constantly true…

a person who tells a great story appreciates hearing one back.

It is almost an unwritten rule and numerous a time I’ve listened to a guy finish tellin’ a story and then he looks at me like ‘alright… what do you got?’

I’ve dug hearing wonderful stories since I was a kid and my grandfather told me all sorts of stories about Planet War Two in the Pacific.

I couldn’t get adequate of those stories and everytime I saw him it was the very first thing I asked him…

‘tell me one more story grampa.’

I utilized to sit there and visualize the stories he told.

I’d really ‘see’ what he was speaking about in my thoughts and in my memories I can nevertheless ‘see’ his stories today.

I remember the way the sun glinted off the wings of the Japanese Zero Fighter that turned into his position and began firing it is machine guns at him and his buddies…

the muzzle flashes of the guns in the wings of that plane and the seconds later sound of spent brass bullet cartridges hitting the ground with a ‘tinging’ noise.

I could ‘smell’ the sweat of fear as he jumped into a foxhole and stated a few words to God as that plane flew overhead.

Shit like that tends to make a very good story and as Irish as my grandfather was the stories usually improved with a small bit of whiskey so as I grew older and encouraged him to drink more the very same stories just kept obtaining better and better.

They got even greater when he encouraged me to take a handful of sips of the whiskey.

‘How did you Feel when that plane pointed right at you and started shooting’ I asked him when.

Man I actually miss that man and his stories.

I want I’d have recorded them all.

He gave me that and those had been the ideal memories of my childhood.

Stories have gotten me into difficulty and stories have gotten me out of it.

I’d just gotten kicked out of Japan for stabbin’ a guy with a broken beer bottle.

Never be concerned…

I’m not a violent thug…

the dude broke into my residence wearing a mask and I woke up none as well sober following a excellent night at The Pig and The Whistle bar in Osaka.

It was kinda weird because I woke up punching some stranger in the face right over my futon.

He was wearing what looked like a white pillow case with eye holes reduce into it and I’d broken his nose by the time I ‘really’ woke up so my very first recollection of the complete issue was hunting at my proper fist about to hit the guy’s face once more and all kindsa blood on his mask.

I was confused as shit.

‘What was I performing… and who’s face was I pummeling’ I wondered as I took another punch.

‘Why am I doing this’ I asked myself.

I knew I must’ve had a genuinely good purpose even though.

I was actually hoping it wasn’t my roommate playing some sort of a joke.

Which was confirmed when he came around screaming behind me.

He was kinda confused too.

In that split second exactly where I stopped attempting to kill the guy and ask my roommate what the fuck was going on the guy took expert benefit of that distraction and proceeded to try to kill me.

I had no notion what the hell was going on but fairly basically place the guy was attempting to kill me so I figured that if I could stay away from that that maybe I could figure it all out later.

I didn’t know what to do.

I did not actually wanna kill the guy…

I was just tryin’ to get some sleep right after all of these Asahi’s and now appear what I gotta deal with.

Well…

for some purpose I just wanted to throw the guy outta my residence.

Seemed intelligent at the time.

Effectively believed out.

A great strategy even.

The thought of holding him ’til the police came by no means even entered my thoughts.

Possibly since we did not have a phone and I wouldn’t know how to contact the cops in Japan anyway.

I do not even bear in mind how I got the empty Asahi bottle in my hand or how it got broken like that.

I mighta taken it away from him.

My roommate was no support at all…

he was screamin’ like a small girl who just saw a nasty spider and the shock of the entire point just rendered him incapacitated as all get out.

I can realize his gettin’ freaked out.

As crazy as it is wakin’ up findin’ your self tryin’ to kill a guy it really is prolly crazier to wake up watchin’ your roommate tryin’ to kill some masked guy in your property.

Busy as I was tryin’ to kill the guy I didn’t have the luxury of freakin’ out.

Somehow with the jagged beer bottle in my proper hand and the dude with a broken nose in a headlock in my left arm I got to the front door… perhaps he’d left it open when he broke in simply because I never know how I could even have opened it with my hands full of hell like that.

And I know my roommate did not open it.

By this time he’d gone fetal on the floor.

Occasionally I wonder about my reactions that evening.

I didn’t believe about callin’ the police till it was all more than.

Instinct told me that life would be a lot much better if the guy who was tryin’ to kill me wasn’t in my property any longer.

It all occurred so quick.

When I threw him out the door somehow I pulled the guys mask off.

I felt like I hadda see his face.

When I did that he turned back on me in this rage that I’d in no way observed in a person just before.

He was goin’ for me difficult and I just sort of without much considering stabbed him in the stomach with the jagged beer bottle.

I had never ever stabbed any individual prior to and appropriate right after I did it I was tellin’ myself ‘dude… you just stabbed a guy.’

Sort of a weird point to consider.

I guess I believed perhaps he’d just die then.

I don’t know… I in no way killed a guy with a broken beer bottle to the gut ahead of.

The entire thing was a new experience.

I imply… I stuck him pretty good.

Shards of glass stuck in his stomach and some other shards fell onto the tile floor.

He got this genuinely shocked appear on his face for a second…

like ‘why the fuck did you just stab me asshole?’

There wasn’t time to say ‘because I woke up with you tryin’ to kill me dickhead.’

In addition to… I didn’t know how to say that in japanese.

As an alternative he recovered from his initial shock and came at me again.

I couldn’t believe this guy.

And my freakin’ out area mate is freakin’ out even much more ’cause now I just stabbed the guy.

It wasn’t like I was left with a complete lotta options man.

The complete scenario was a lot to deal with and I was beginning to get pissed off.

I was woken up adequate by that time that I ultimately decided to kill the guy with my bare hands.

I’d had adequate of this shit you know?

Didja ever just try to get some sleep and all of the sudden you gotta kill a guy?

A guy who appears hell bent on killin’ you?

I wasn’t angry or mad or filled with hatred… I just wanted some peace in my life and this guy’s fully going apeshit on me and we look to have differing agendas on how the evening need to end.

And I still never know what the complete thing’s all about.

We fought there in the hallway in front of the front door…

It was comedic really in a way when I believe back on it…

there was so much blood on the floor and I am barefoot in my underwear tryin’ to kill the guy but I can’t hold from slipping in the blood.

Could not keep on my feet for all the cash in the world.

Neither could he.

We ended up wrestling on the floor.

Blood on porcelain tile is truly slippery.

I feel losin’ as considerably blood as he did just took the fight out of him.

The last couple of throws from either of us had been weak and exasperating.

I don’t know what told me to let him go but I did.

Anything just told me it was all over.

He stumbled down the hallway and I went back inside.

The hallway was a bloody mess.

It was blood all more than the floor… bloody smeared handprints on the wall…

I sat down on my futon and tried to figure out if any of the blood that covered me was mine.

Did a tiny examination of all my extremities and such.

Nothin’.

A couple of cuts on my feet possibly from walking on the broken glass.

Now is exactly where I started to get angry.

I did not ask for any of that.

I tried asking my space mate what the fuck that was all about but all he could do was talk gibberish.

He couldn’t even get the words out.

I don’t know who known as the cops and they seemed to show up pretty swiftly.

Lots of them.

Now I hadda deal with that shit as well.

I couldn’t even get dressed and go wash the blood off.

They would not let me.

Because they were as well busy taking photographs of me and the blood I was wearing.

The 1st issue the cops asked when they got there and saw the bloody mess in the hallway was ‘where is the physique.’

Come on man.

Some dude just broke into my residence for factors unknown in a mask and tried to kill me and freaked the shit out of my roommate.

And now I gotta be interrogated?

I actually just wanted to take a shower and go back to sleep.

I knew sufficient japanese to score with the ladies but I had no idea how to talk to these guys.

It was crazy mojo all the way about…

and I told them what occurred but they kept treating me like the criminal right here.

Which it turned out they presumed me to be.

Due to the fact I stabbed the guy Outdoors of my house.

And I told them that.

Awwwwww fuck.

It is funny how items go that way.

It all made ideal sense at the time.

I did not believe… ‘don’t stab the guy since he’s outside of your property and it is a whole distinct ballgame if you kill him there versus killin’ him in your bedroom according to the law.’

But it was.

That is where I learned it’s usually far better to get in touch with your lawyer prior to you contact the police.

Lawyers are far better at making up stories in the middle of the night than you or I will ever be.

Not that I thought I necessary a story…

it seemed fairly clear what had occurred.

But the ‘lack of a body’ seemed to get everybody upset.

After lots and lots of interrogation I was just advised by the police the next morning that everything would be much better if I just left Japan proper away.

Like now.

Just before I was charged with something like murder.

If they located that guy’s physique.

So I quickly packed up my backpack and decided to take their guidance.

I cleaned up… shared a coffee with the roomie who could talk now and told him I’d hold in touch.

The very best way out I’d figured was the Port of Osaka.

There’s all types of ships comin’ in and out and I knew I could hitch a ride with a single.

Sailors don’t ask also a lot of concerns.

Australia was soundin’ good and I’d told my space mate that prior to I left.

‘I’ll send you a postcard’ I told him.

I couldn’t discover a ship headed to Australia that day… but there was 1 heading to Shanghai and that was like half way according to my map.

I figured I’d hafta try and jump yet another ship right there in Shanghai.

I’d consider about all that when I got there.

When I approached the ship I asked one of the crew memebers if I may well be capable to difficulty them for a ride to Shanghai.

‘Whaddaya got’ of of the sailors mentioned… starting the negotiations over how significantly the fare was gonna cost me.

‘I’m a great story teller’ I mentioned.

From Wikipedia

Joseph Fernand Henri Léger (French: [leʒe] February 4, 1881 – August 17, 1955) was a French painter, sculptor, and filmmaker. In his early functions he developed a individual form of cubism which he gradually modified into a a lot more figurative, populist style. His boldly simplified remedy of modern day subject matter has caused him to be regarded as a forerunner of pop art.

Biography

Léger was born in Argentan, Orne, Decrease Normandy, exactly where his father raised cattle. Fernand Léger initially educated as an architect from 1897 to 1899, just before moving in 1900 to Paris, exactly where he supported himself as an architectural draftsman. Right after military service in Versailles, Yvelines, in 1902–1903, he enrolled at the School of Decorative Arts following his application to the École des Beaux-Arts was rejected. He nonetheless attended the Beaux-Arts as a non-enrolled student, spending what he described as &quotthree empty and useless years&quot studying with Gérôme and other individuals, while also studying at the Académie Julian.[1] He started to work seriously as a painter only at the age of 25. At this point his work showed the influence of impressionism, as seen in Le Jardin de ma mère (My Mother’s Garden) of 1905, 1 of the handful of paintings from this period that he did not later destroy. A new emphasis on drawing and geometry appeared in Léger’s operate right after he saw the Cézanne retrospective at the Salon d’Automne in 1907.[two]

1909–1914

A painting of a woman in blue
La Femme en Bleu (Woman in Blue), 1912, oil on canvas, 193 x 129.9 cm (76 x 51 1/eight inches), Kunstmuseum Basel. Exhibited at the 1912 Salon d’Automne, Paris
Painting of a nude
Nude Model in the Studio (Le modèle nu dans l’atelier), 1912-13, oil on burlap, 128.6 x 95.9 cm, Solomon R. Guggenheim Museum, New York
In 1909 he moved to Montparnasse and met such leaders of the avant-garde as Archipenko, Lipchitz, Chagall, Joseph Csaky and Robert Delaunay. His significant painting of this period is Nudes in the Forest (1909–10), in which Léger displays a personal form of Cubism that his critics termed &quotTubism&quot for its emphasis on cylindrical forms.[three]

In 1910 he exhibited at the Salon d’Automne in the identical area (salle VIII) with Jean Metzinger and Henri Le Fauconnier. In 1911 the hanging committee of the Salon des Indépendants placed together the painters that would quickly be identified as ‘Cubists’. Metzinger, Gleizes, Le Fauconnier, Delaunay and Léger were accountable for revealing Cubism to the basic public for the initial time as an organized group.

The following year he once more exhibited at the Salon d’Automne and Indépendants with the Cubists, and joined with many artists, which includes Henri Le Fauconnier, Jean Metzinger, Albert Gleizes, Francis Picabia and the Duchamp brothers, Jacques Villon, Raymond Duchamp-Villon and Marcel Duchamp to form the Puteaux Group—also known as the Section d’Or (The Golden Section).

Léger’s paintings, from then until 1914, became increasingly abstract. Their tubular, conical, and cubed forms are laconically rendered in rough patches of primary colors plus green, black and white, as noticed in the series of paintings with the title Contrasting Types. Léger created no use of the collage method pioneered by Braque and Picasso.[4]

1914–1920

Léger’s experiences in World War I had a substantial effect on his operate. Mobilized in August 1914 for service in the French Army, he spent two years at the front in Argonne.[5] He developed a lot of sketches of artillery pieces, airplanes, and fellow soldiers although in the trenches, and painted Soldier with a Pipe (1916) while on furlough. In September 1916 he virtually died following a mustard gas attack by the German troops at Verdun. Throughout a period of convalescence in Villepinte he painted The Card Players (1917), a canvas whose robot-like, monstrous figures reflect the ambivalence of his knowledge of war. As he explained:

…I was stunned by the sight of the breech of a 75 millimeter in the sunlight. It was the magic of light on the white metal. That’s all it took for me to forget the abstract art of 1912–1913. The crudeness, range, humor, and downright perfection of specific guys about me, their precise sense of utilitarian reality and its application in the midst of the life-and-death drama we were in … created me want to paint in slang with all its colour and mobility.

This perform marked the starting of his &quotmechanical period&quot, for the duration of which the figures and objects he painted were characterized by sleekly rendered tubular and machine-like types. Starting in 1918, he also developed the first paintings in the Disk series, in which disks suggestive of targeted traffic lights figure prominently.[7] In December 1919 he married Jeanne-Augustine Lohy, and in 1920 he met Le Corbusier, who would stay a lifelong friend.

1920

Still Life with a Beer Mug, 1921, oil on canvas, the Tate
The &quotmechanical&quot operates Léger painted in the 1920s, in their formal clarity as effectively as in their subject matter—the mother and child, the female nude, figures in an ordered landscape—are common of the postwar &quotreturn to order&quot in the arts, and link him to the tradition of French figurative painting represented by Poussin and Corot.[8] In his paysages animés (animated landscapes) of 1921, figures and animals exist harmoniously in landscapes created up of streamlined types. The frontal compositions, firm contours, and smoothly blended colors of these paintings frequently recall the operates of Henri Rousseau, an artist Léger greatly admired and whom he had met in 1909.

They also share traits with the perform of Le Corbusier and Amédée Ozenfant who with each other had founded Purism, a style intended as a rational, mathematically based corrective to the impulsiveness of cubism. Combining the classical with the contemporary, Léger’s Nude on a Red Background (1927) depicts a monumental, expressionless lady, machinelike in form and colour. His still life compositions from this period are dominated by stable, interlocking rectangular formations in vertical and horizontal orientation. The Siphon of 1924, a still life based on an advertisement in the popular press for the aperitif Campari, represents the high-water mark of the Purist aesthetic in Léger’s perform.[9] Its balanced composition and fluted shapes suggestive of classical columns are brought together with a quasi-cinematic close-up of a hand holding a bottle.

As an enthusiast of the modern, Léger was significantly attracted to cinema, and for a time he deemed providing up painting for filmmaking.[ten] In 1923–24 he made the set for the laboratory scene in Marcel L’Herbier’s L’Inhumaine (The Inhuman A single). In 1924, in collaboration with Dudley Murphy, George Antheil, and Man Ray, Léger developed and directed the iconic and Futurism-influenced film, Ballet Mécanique (Mechanical Ballet). Neither abstract nor narrative, it is a series of pictures of a woman’s lips and teeth, close-up shots of ordinary objects, and repeated photos of human activities and machines in rhythmic movement.[11]

In collaboration with Amédée Ozenfant he established a totally free college exactly where he taught from 1924, with Alexandra Exter and Marie Laurencin. He produced the first of his &quotmural paintings&quot, influenced by Le Corbusier’s theories, in 1925. Intended to be incorporated into polychrome architecture, they are amongst his most abstract paintings, featuring flat regions of color that seem to advance or recede.[12]

1930s

Starting in 1927, the character of Léger’s perform steadily changed as organic and irregular types assumed greater significance.[13] The figural style that emerged in the 1930s is totally displayed in the Two Sisters of 1935, and in a number of versions of Adam and Eve.[14] With characteristic humor, he portrayed Adam in a striped bathing suit, or sporting a tattoo.

In 1931, Léger produced his 1st pay a visit to to the United States, exactly where he traveled to New York City and Chicago.[15] In 1935, the Museum of Modern Art in New York City presented an exhibition of his operate. In 1938, Léger was commissioned to decorate Nelson Rockefeller’s apartment.[16]

The War years

In the course of Globe War II Léger lived in the United States. He taught at Yale University, and located inspiration for a new series of paintings in the novel sight of industrial refuse in the landscape. The shock of juxtaposed all-natural forms and mechanical components, the &quottons of abandoned machines with flowers cropping up from within, and birds perching on leading of them&quot exemplified what he known as the &quotlaw of contrast&quot.[17] His enthusiasm for such contrasts resulted in such operates as The Tree in the Ladder of 1943–44, and Romantic Landscape of 1946. A significant perform of 1944, 3 Musicians (Museum of Modern day Art, New York), reprises a composition of 1930. A folk-like composition reminiscent of Rousseau, it exploits the law of contrasts in its realistic juxtaposition of the three males and their instruments.

Upon his return to France in 1945, he joined the Communist Party.[18] In the course of this period his perform became less abstract, and he developed numerous monumental figure compositions depicting scenes of well-liked life featuring acrobats, builders, divers, and country outings. Art historian Charlotta Kotik has written that Léger’s &quotdetermination to depict the common man, as properly as to develop for him, was a result of socialist theories widespread amongst the avant-garde each prior to and after Globe War II. Even so, Léger’s social conscience was not that of a fierce Marxist, but of a passionate humanist&quot.[19] His varied projects included book illustrations, murals, stained-glass windows, mosaics, polychrome ceramic sculptures, and set and costume styles.

1950

Following the death of his wife in 1950, Léger married Nadia Khodossevitch in 1952. In his final years he lectured in Bern, developed mosaics and stained-glass windows for the Central University of Venezuela in Caracas, Venezuela, and painted Country Outing, The Camper, and the series The Big Parade. In 1954 he started a project for a mosaic for the São Paulo Opera, which he would not live to finish. Fernand Léger died at his residence in 1955 and is buried in Gif-sur-Yvette, Essonne.

Legacy

Léger wrote in 1945 that &quotthe object in contemporary painting must become the major character and overthrow the topic. If, in turn, the human type becomes an object, it can considerably liberate possibilities for the contemporary artist.&quot He elaborated on this concept in his 1949 essay, &quotHow I Conceive the Human Figure&quot, where he wrote that &quotabstract art came as a total revelation, and then we have been capable to contemplate the human figure as a plastic worth, not as a sentimental value. That is why the human figure has remained willfully inexpressive throughout the evolution of my function&quot.[20] As the 1st painter to take as his idiom the imagery of the machine age, and to make the objects of customer society the subjects of his paintings, Léger has been known as a progenitor of Pop art.[21]

He was active as a teacher for several years. Among his pupils had been Nadir Afonso, Robert Colescott, Paul Georges, Charlotte Gilbertson, Hananiah Harari, Asger Jorn, Michael Loew, Beverly Pepper, Victor Reinganum, Marcel Mouly, George L. K. Morris, René Margotton, Erik Olson, Saloua Raouda Choucair and Charlotte Wankel.

In 1952, a pair of Léger murals was installed in the General Assembly Hall of the United Nations headquarters in New York, New York.[22]

In 1960, the Musée Fernand Léger was opened in Biot, Alpes-Maritimes, France.

In May possibly 2008, his painting, Étude pour la femme en bleu (1912-13) sold for ,241,000 (hammer price tag with buyer’s premium) United States dollars.[23]

In August 2008, a single of Léger’s paintings owned by Wellesley College’s Davis Museum and Cultural Center, Mother and Youngster, was reported missing. It is believed to have disappeared some time between April 9, 2007 and November 19, 2007. A ,000 reward is becoming provided for information that leads to the protected return of the painting.[24]

Léger’s function was featured in the exhibition &quotLéger: Modern Art and the Metropolis&quot from October 14, 2013, by way of January 5, 2014, at the Philadelphia Museum of Art.[25]

Details, quoting from Smithsonian National Air and Space Museum | Vought F4U-1D Corsair:

By V-J Day, September 2, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design allowed ground clearance for the huge, three-bladed Hamilton Standard Hydromatic propeller, which spanned more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the largest and one of the most powerful engine-propeller combinations ever flown on a fighter aircraft.

Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-support fighter assigned to the USS Essex in July 1944.

Long Description:
On February 1, 1938, the United States Navy Bureau of Aeronautics requested proposals from American aircraft manufacturers for a new carrier-based fighter airplane. During April, the Vought Aircraft Corporation responded with two designs and one of them, powered by a Pratt & Whitney R-2800 engine, won the competition in June. Less than a year later, Vought test pilot Lyman A. Bullard, Jr., first flew the Vought XF4U-1 prototype on May 29, 1940. At that time, the largest engine driving the biggest propeller ever flown on a fighter aircraft propelled Bullard on this test flight. The R-2800 radial air-cooled engine developed 1,850 horsepower and it turned a three-blade Hamilton Standard Hydromatic propeller with solid aluminum blades spanning 13 feet 1 inch.

The airplane Bullard flew also had another striking feature, a wing bent gull-shaped on both sides of the fuselage. This arrangement gave additional ground clearance for the propeller and reduced drag at the wing-to-fuselage joint. Ironically for a 644-kph (400 mph) airplane, Vought covered the wing with fabric behind the main spar, a practice the company also followed on the OS2U Kingfisher (see NASM collection).

When naval air strategists had crafted the requirements for the new fighter, the need for speed had overridden all other performance goals. With this in mind, the Bureau of Aeronautics selected the most powerful air-cooled engine available, the R-2800. Vought assembled a team, lead by chief designer Rex Biesel, to design the best airframe around this powerful engine. The group included project engineer Frank Albright, aerodynamics engineer Paul Baker, and propulsion engineer James Shoemaker. Biesel and his team succeeded in building a very fast fighter but when they redesigned the prototype for production, they were forced to make an unfortunate compromise.

The Navy requested heavier armament for production Corsairs and Biesel redesigned each outboard folding wing panel to carry three .50 caliber machine guns. These guns displaced fuel tanks installed in each wing leading edge. To replace this lost capacity, an 897-liter (237 gal) fuselage tank was installed between the cockpit and the engine. To maintain the speedy and narrow fuselage profile, Biesel could not stack the cockpit on top of the tank, so he moved it nearly three feet aft. Now the wing completely blocked the pilot’s line of sight during the most critical stages of landing. The early Corsair also had a vicious stall, powerful torque and propeller effects at slow speed, a short tail wheel strut, main gear struts that often bounced the airplane at touchdown, and cowl flap actuators that leaked oil onto the windshield. These difficulties, combined with the lack of cockpit visibility, made the airplane nearly impossible to land on the tiny deck of an aircraft carrier. Navy pilots soon nicknamed the F4U the ‘ensign eliminator’ for its tendency to kill these inexperienced aviators. The Navy refused to clear the F4U for carrier operations until late in 1944, more than seven years after the project started.

This flaw did not deter the Navy from accepting Corsairs because Navy and Marine pilots sorely needed an improved fighter to replace the Grumman F4F Wildcat (see NASM collection). By New Year’s Eve, 1942, the service owned 178 F4U-1 airplanes. Early in 1943, the Navy decided to divert all Corsairs to land-based United States Marine Corps squadrons and fill Navy carrier-based units with the Grumman F6F Hellcat (see NASM collection). At its best speed of 612 kph (380 mph) at 6,992 m (23,000 ft), the Hellcat was about 24 kph (15 mph) slower than the Corsair but it was a joy to fly aboard the carrier. The F6F filled in splendidly until improvements to the F4U qualified it for carrier operations. Meanwhile, the Marines on Guadalcanal took their Corsairs into combat and engaged the enemy for the first time on February 14, 1943, six months before Hellcat pilots on that battle-scared island first encountered enemy aircraft.

The F4U had an immediate impact on the Pacific air war. Pilots could use the Corsair’s speed and firepower to engage the more maneuverable Japanese airplanes only when the advantage favored the Americans. Unprotected by armor or self-sealing fuel tanks, no Japanese fighter or bomber could withstand for more than a few seconds the concentrated volley from the six .50 caliber machine guns carried by a Corsair. Major Gregory "Pappy" Boyington assumed command of Marine Corsair squadron VMF-214, nicknamed the ‘Black Sheep’ squadron, on September 7, 1943. During less than 5 months of action, Boyington received credit for downing 28 enemy aircraft. Enemy aircraft shot him down on January 3, 1944, but he survived the war in a Japanese prison camp.

In May and June 1944, Charles A. Lindbergh flew Corsair missions with Marine pilots at Green Island and Emirau. On September 3, 1944, Lindbergh demonstrated the F4U’s bomb hauling capacity by flying a Corsair from Marine Air Group 31 carrying three bombs each weighing 450 kg (1,000 lb). He dropped this load on enemy positions at Wotje Atoll. On the September 8, Lindbergh dropped the first 900-kg (2,000 lb) bomb during an attack on the atoll. For the finale five days later, the Atlantic flyer delivered a 900-kg (2,000 lb) bomb and two 450-kg (1,000 lb) bombs. Lindbergh went ahead and flew these missions after the commander of MAG-31 informed him that if he was forced down and captured, the Japanese would almost certainly execute him.

As of V-J Day, September 2, 1945, the Navy credited Corsair pilots with destroying 2,140 enemy aircraft in aerial combat. The Navy and Marines lost 189 F4Us in combat and 1,435 Corsairs in non-combat accidents. Beginning on February 13, 1942, Marine and Navy pilots flew 64,051 operational sorties, 54,470 from runways and 9,581 from carrier decks. During the war, the British Royal Navy accepted 2,012 Corsairs and the Royal New Zealand Air Force accepted 364. The demand was so great that the Goodyear Aircraft Corporation and the Brewster Aeronautical Corporation also produced the F4U.

Corsairs returned to Navy carrier decks and Marine airfields during the Korean War. On September 10, 1952, Captain Jesse Folmar of Marine Fighter Squadron VMF-312 destroyed a MiG-15 in aerial combat over the west coast of Korea. However, F4U pilots did not have many air-to-air encounters over Korea. Their primary mission was to support Allied ground units along the battlefront.

After the World War II, civilian pilots adapted the speedy bent-wing bird from Vought to fly in competitive air races. They preferred modified versions of the F2G-1 and -2 originally built by Goodyear. Corsairs won the prestigious Thompson Trophy twice. In 1952, Vought manufactured 94 F4U-7s for the French Navy, and these aircraft saw action over Indochina but this order marked the end of Corsair production. In production longer than any other U.S. fighter to see service in World War II, Vought, Goodyear, and Brewster built a total of 12,582 F4Us.

The United States Navy donated an F4U-1D to the National Air and Space Museum in September 1960. Vought delivered this Corsair, Bureau of Aeronautics serial number 50375, to the Navy on April 26, 1944. By October, pilots of VF-10 were flying it but in November, the airplane was transferred to VF-89 at Naval Air Station Atlantic City. It remained there as the squadron moved to NAS Oceana and NAS Norfolk. During February 1945, the Navy withdrew the airplane from active service and transferred it to a pool of surplus aircraft stored at Quantico, Virginia. In 1980, NASM craftsmen restored the F4U-1D in the colors and markings of a Corsair named "Sun Setter," a fighter assigned to Marine Fighter Squadron VMF-114 when that unit served aboard the "USS Essex" in July 1944.

Quoting from Wikipedia | Vought F4U Corsair:

The Chance Vought F4U Corsair was a carrier-capable fighter aircraft that saw service primarily in World War II and the Korean War. Demand for the aircraft soon overwhelmed Vought’s manufacturing capability, resulting in production by Goodyear and Brewster: Goodyear-built Corsairs were designated FG and Brewster-built aircraft F3A. From the first prototype delivery to the U.S. Navy in 1940, to final delivery in 1953 to the French, 12,571 F4U Corsairs were manufactured by Vought, in 16 separate models, in the longest production run of any piston-engined fighter in U.S. history (1942–1953).

The Corsair served in the U.S. Navy, U.S. Marines, Fleet Air Arm and the Royal New Zealand Air Force, as well as the French Navy Aeronavale and other, smaller, air forces until the 1960s. It quickly became the most capable carrier-based fighter-bomber of World War II. Some Japanese pilots regarded it as the most formidable American fighter of World War II, and the U.S. Navy counted an 11:1 kill ratio with the F4U Corsair.

F4U-1D (Corsair Mk IV): Built in parallel with the F4U-1C, but was introduced in April 1944. It had the new -8W water-injection engine. This change gave the aircraft up to 250 hp (190 kW) more power, which, in turn, increased performance. Speed, for example, was boosted from 417 miles per hour (671 km/h) to 425 miles per hour (684 km/h). Because of the U.S. Navy’s need for fighter-bombers, it had a payload of rockets double the -1A’s, as well as twin-rack plumbing for an additional belly drop tank. Such modifications necessitated the need for rocket tabs (attached to fully metal-plated underwing surfaces) and bomb pylons to be bolted on the fighter, however, causing extra drag. Additionally, the role of fighter-bombing was a new task for the Corsair and the wing fuel cells proved too vulnerable and were removed.[] The extra fuel carried by the two drop tanks would still allow the aircraft to fly relatively long missions despite the heavy, un-aerodynamic load. The regular armament of six machine guns were implemented as well. The canopies of most -1Ds had their struts removed along with their metal caps, which were used — at one point — as a measure to prevent the canopies’ glass from cracking as they moved along the fuselage spines of the fighters.[] Also, the clear-view style "Malcolm Hood" canopy used initially on Supermarine Spitfire and P-51C Mustang aircraft was adopted as standard equipment for the -1D model, and all later F4U production aircraft. Additional production was carried out by Goodyear (FG-1D) and Brewster (F3A-1D). In Fleet Air Arm service, the latter was known as the Corsair III, and both had their wingtips clipped by 8" per wing to allow storage in the lower hangars of British carriers.

Quoting Smithsonian National Air and Space Museum | Concorde, Fox Alpha, Air France:

The first supersonic airliner to enter service, the Concorde flew thousands of passengers across the Atlantic at twice the speed of sound for over 25 years. Designed and built by Aérospatiale of France and the British Aviation Corporation, the graceful Concorde was a stunning technological achievement that could not overcome serious economic problems.

In 1976 Air France and British Airways jointly inaugurated Concorde service to destinations around the globe. Carrying up to 100 passengers in great comfort, the Concorde catered to first class passengers for whom speed was critical. It could cross the Atlantic in fewer than four hours – half the time of a conventional jet airliner. However its high operating costs resulted in very high fares that limited the number of passengers who could afford to fly it. These problems and a shrinking market eventually forced the reduction of service until all Concordes were retired in 2003.

In 1989, Air France signed a letter of agreement to donate a Concorde to the National Air and Space Museum upon the aircraft’s retirement. On June 12, 2003, Air France honored that agreement, donating Concorde F-BVFA to the Museum upon the completion of its last flight. This aircraft was the first Air France Concorde to open service to Rio de Janeiro, Washington, D.C., and New York and had flown 17,824 hours.

Details, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in more hostile airspace or with such complete impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War.

This Blackbird accrued about 2,800 hours of flight time during 24 years of active service with the U.S. Air Force. On its last flight, March 6, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilometers (2,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane over to the Smithsonian.

Long Description:
No reconnaissance aircraft in history has operated in more hostile airspace or with such complete impunity than the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a full-blown crisis in the mid-1950s. U.S. military commanders desperately needed accurate assessments of Soviet worldwide military deployments, particularly near the Iron Curtain. Lockheed Aircraft Corporation’s subsonic U-2 (see NASM collection) reconnaissance aircraft was an able platform but the U. S. Air Force recognized that this relatively slow aircraft was already vulnerable to Soviet interceptors. They also understood that the rapid development of surface-to-air missile systems could put U-2 pilots at grave risk. The danger proved reality when a U-2 was shot down by a surface to air missile over the Soviet Union in 1960.

Lockheed’s first proposal for a new high speed, high altitude, reconnaissance aircraft, to be capable of avoiding interceptors and missiles, centered on a design propelled by liquid hydrogen. This proved to be impracticable because of considerable fuel consumption. Lockheed then reconfigured the design for conventional fuels. This was feasible and the Central Intelligence Agency (CIA), already flying the Lockheed U-2, issued a production contract for an aircraft designated the A-12. Lockheed’s clandestine ‘Skunk Works’ division (headed by the gifted design engineer Clarence L. "Kelly" Johnson) designed the A-12 to cruise at Mach 3.2 and fly well above 18,288 m (60,000 feet). To meet these challenging requirements, Lockheed engineers overcame many daunting technical challenges. Flying more than three times the speed of sound generates 316° C (600° F) temperatures on external aircraft surfaces, which are enough to melt conventional aluminum airframes. The design team chose to make the jet’s external skin of titanium alloy to which shielded the internal aluminum airframe. Two conventional, but very powerful, afterburning turbine engines propelled this remarkable aircraft. These power plants had to operate across a huge speed envelope in flight, from a takeoff speed of 334 kph (207 mph) to more than 3,540 kph (2,200 mph). To prevent supersonic shock waves from moving inside the engine intake causing flameouts, Johnson’s team had to design a complex air intake and bypass system for the engines.

Skunk Works engineers also optimized the A-12 cross-section design to exhibit a low radar profile. Lockheed hoped to achieve this by carefully shaping the airframe to reflect as little transmitted radar energy (radio waves) as possible, and by application of special paint designed to absorb, rather than reflect, those waves. This treatment became one of the first applications of stealth technology, but it never completely met the design goals.

Test pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, after he became airborne accidentally during high-speed taxi trials. The airplane showed great promise but it needed considerable technical refinement before the CIA could fly the first operational sortie on May 31, 1967 – a surveillance flight over North Vietnam. A-12s, flown by CIA pilots, operated as part of the Air Force’s 1129th Special Activities Squadron under the "Oxcart" program. While Lockheed continued to refine the A-12, the U. S. Air Force ordered an interceptor version of the aircraft designated the YF-12A. The Skunk Works, however, proposed a "specific mission" version configured to conduct post-nuclear strike reconnaissance. This system evolved into the USAF’s familiar SR-71.

Lockheed built fifteen A-12s, including a special two-seat trainer version. Two A-12s were modified to carry a special reconnaissance drone, designated D-21. The modified A-12s were redesignated M-21s. These were designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a pylon between the rudders. The M-21 then hauled the drone aloft and launched it at speeds high enough to ignite the drone’s ramjet motor. Lockheed also built three YF-12As but this type never went into production. Two of the YF-12As crashed during testing. Only one survives and is on display at the USAF Museum in Dayton, Ohio. The aft section of one of the "written off" YF-12As which was later used along with an SR-71A static test airframe to manufacture the sole SR-71C trainer. One SR-71 was lent to NASA and designated YF-12C. Including the SR-71C and two SR-71B pilot trainers, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Because of extreme operational costs, military strategists decided that the more capable USAF SR-71s should replace the CIA’s A-12s. These were retired in 1968 after only one year of operational missions, mostly over southeast Asia. The Air Force’s 1st Strategic Reconnaissance Squadron (part of the 9th Strategic Reconnaissance Wing) took over the missions, flying the SR-71 beginning in the spring of 1968.

After the Air Force began to operate the SR-71, it acquired the official name Blackbird– for the special black paint that covered the airplane. This paint was formulated to absorb radar signals, to radiate some of the tremendous airframe heat generated by air friction, and to camouflage the aircraft against the dark sky at high altitudes.

Experience gained from the A-12 program convinced the Air Force that flying the SR-71 safely required two crew members, a pilot and a Reconnaissance Systems Officer (RSO). The RSO operated with the wide array of monitoring and defensive systems installed on the airplane. This equipment included a sophisticated Electronic Counter Measures (ECM) system that could jam most acquisition and targeting radar. In addition to an array of advanced, high-resolution cameras, the aircraft could also carry equipment designed to record the strength, frequency, and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was designed to fly deep into hostile territory, avoiding interception with its tremendous speed and high altitude. It could operate safely at a maximum speed of Mach 3.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth. The crew had to wear pressure suits similar to those worn by astronauts. These suits were required to protect the crew in the event of sudden cabin pressure loss while at operating altitudes.

To climb and cruise at supersonic speeds, the Blackbird’s Pratt & Whitney J-58 engines were designed to operate continuously in afterburner. While this would appear to dictate high fuel flows, the Blackbird actually achieved its best "gas mileage," in terms of air nautical miles per pound of fuel burned, during the Mach 3+ cruise. A typical Blackbird reconnaissance flight might require several aerial refueling operations from an airborne tanker. Each time the SR-71 refueled, the crew had to descend to the tanker’s altitude, usually about 6,000 m to 9,000 m (20,000 to 30,000 ft), and slow the airplane to subsonic speeds. As velocity decreased, so did frictional heat. This cooling effect caused the aircraft’s skin panels to shrink considerably, and those covering the fuel tanks contracted so much that fuel leaked, forming a distinctive vapor trail as the tanker topped off the Blackbird. As soon as the tanks were filled, the jet’s crew disconnected from the tanker, relit the afterburners, and again climbed to high altitude.

Air Force pilots flew the SR-71 from Kadena AB, Japan, throughout its operational career but other bases hosted Blackbird operations, too. The 9th SRW occasionally deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were flown directly from Beale. The SR-71 did not begin to operate in Europe until 1974, and then only temporarily. In 1982, when the U.S. Air Force based two aircraft at Royal Air Force Base Mildenhall to fly monitoring mission in Eastern Europe.

When the SR-71 became operational, orbiting reconnaissance satellites had already replaced manned aircraft to gather intelligence from sites deep within Soviet territory. Satellites could not cover every geopolitical hotspot so the Blackbird remained a vital tool for global intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 provided information that proved vital in formulating successful U. S. foreign policy. Blackbird crews provided important intelligence about the 1973 Yom Kippur War, the Israeli invasion of Lebanon and its aftermath, and pre- and post-strike imagery of the 1986 raid conducted by American air forces on Libya. In 1987, Kadena-based SR-71 crews flew a number of missions over the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened commercial shipping and American escort vessels.

As the performance of space-based surveillance systems grew, along with the effectiveness of ground-based air defense networks, the Air Force started to lose enthusiasm for the expensive program and the 9th SRW ceased SR-71 operations in January 1990. Despite protests by military leaders, Congress revived the program in 1995. Continued wrangling over operating budgets, however, soon led to final termination. The National Aeronautics and Space Administration retained two SR-71As and the one SR-71B for high-speed research projects and flew these airplanes until 1999.

On March 6, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This special airplane bore Air Force serial number 64-17972. Lt. Col. Ed Yeilding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington D.C. in 1 hour, 4 minutes, and 20 seconds, averaging a speed of 3,418 kph (2,124 mph). At the conclusion of the flight, ‘972 landed at Dulles International Airport and taxied into the custody of the Smithsonian’s National Air and Space Museum. At that time, Lt. Col. Vida had logged 1,392.7 hours of flight time in Blackbirds, more than that of any other crewman.

This particular SR-71 was also flown by Tom Alison, a former National Air and Space Museum’s Chief of Collections Management. Flying with Detachment 1 at Kadena Air Force Base, Okinawa, Alison logged more than a dozen ‘972 operational sorties. The aircraft spent twenty-four years in active Air Force service and accrued a total of 2,801.1 hours of flight time.

That worked out quite properly but it nevertheless took us about two hours and much more than thousand pictures only to get two decent shots.

As the lighting had been far from remarkable I had to shoot at ISO12.800. Photoshop did a fairly very good job denoising it anyways. Denoising also was the only processing applied.

Wrote the Picayune: In October, 1803, it was well known throughout the country that Louisiana had been purchased by the United States. Mr. Taylor was the only merchant who seemed to comprehend the profit from one consequence of the this great political event.

11_all sugar imports thereafter
12_cornered 1800 of those hogsheads
The firm realized that in becoming a state, a duty of 2.5 cents would be added to the price of all sugar imports thereafter. So Shepherd and McDonough – when all the sugar produced in the state was between 2100-2200 hogsheads – cornered 1800 of those hogsheads, giving young RD “a handsome capital for a young man to start in mercantile life.” He soon created a new firm shared with Taylor, then in time through age and retirement became RD’s alone.

13_Coming into his own
Coming into his own, he married Lucy Taylor Gorham of Barnstable, Massachusetts in 1808, who was “a niece and adopted daughter” of Taylor. On August 22nd, 1809, their only child, Ellen Shepherd, was born in Louisiana. (Lucy would die in 1814).

14_the penchant of RD
It was at this juncture the penchant of RD for regular, publicity-averse benefactions took root, in the moment of his willed defiance against a direct military order to work, instead, to save one particular wounded man, left for dead in war, a man who himself would live on to become the epitome of the proverbial Good Man, albeit

an old building in the rear of Jackson’s headquarters. Forgetting his orders, Mr. Shepherd went immediately to the place and found he was not dead, but, as the surgeon said, in a dying condition. Disregarding what the surgeon said, Shepherd got a cart, put him in it, administered stimulants, and took Touro to his own house. He then procured nurses, and by the closest attention, Mr. Touro’s life was saved. Mr. Shepherd returned late in the day,

RD’s businesses continued to grow exponentially and his brother, James Hervey Shepherd, was summoned from Shepherdstown to assist.

1842, June – RD signs a petition to Congress along with numerous other planters and sugar manufacturers in the state of Louisiana that asks for an increase in the duties on imported sugar.

1849 – RD places responsibilities on his eighteen-year-old nephew, Henry Shepherd Jr., who would become his agent in New Orleans through the Civil War, allowing RD to return more permanently to his Wild Goose Farm.

Although one account states Touro stipulated that RD free his enslaved persons, RD is shown to having owned numerous persons, enumerated in both the 1850 and 1860 Census slave schedules.

1854, January 6th – Touro’s Will makes Rezin Davis Shepherd residuary legatee of the estate and executor; 5,000 is willed to specific recipients. A sum iof ,000 is set aside for a palatial almshouse, with the added stipulation to RD that more sums, if needed, should be used to complete this priority project.

Judah Touro made out his will January 6, 1854 a few days before his death that said:

33_my dear, old, and devoted friend, Rezin Davis Shepherd
34_I hereby appoint and institute him
As regards my other designated executor, say my dear, old, and devoted friend, Rezin Davis Shepherd, to whom, under Divine Providence, I am greatly indebted for the preservation of my life when I was wounded on the 1st of January, 1815, I hereby appoint and institute him, the said Rezin Davis Shepherd, after payment of my particular legacies, and the debts of my succession, the universal legatee of the rest and residue of my estates, movable and immovable.

The Shepherd Family is Scattered By War:

37_The war hit the family hard
The war hit the family hard. Most of the young men enlisted in Virginia units. RD had to recalibrate his business strategies. Wrote the Richmond Daily Dispatch: June 8, 1861:
The New Orleans Delta states that R. D. Shepherd, Esq., who is now at an advanced time of life, living on his beautiful farm near Shepherdstown, Virginia, has directed his agent in New Orleans to pay over to the treasurer of the Confederate States a large sum of money, including, it is said, his whole annual income from rents in that city — the largest income enjoyed by any property holder — to be applied to the defence of the rights and the support of the independence of the South.

38_spring of 1862 when Federal General Banks
In the spring of 1862 when Federal General Banks with his army entered into Jefferson County, RD took refuge in Boston with his daughter.

39_As the war progressed
As the war progressed, its maw of destruction came closer to Shepherdstown’s nearly complete building. 130,000 troops moved in the area in September, 1862 for the bloody Maryland Campaign, just across the Potomac river. Wounded from the nearby battles poured into Shepherdstown, putting the unfinished Town Hall into service as an outdoor hospital.

Wrote Mary Bedinger Mitchell:

40_The unfinished Town Hall had stood in naked ugliness
The unfinished Town Hall had stood in naked ugliness for many a long day. Somebody threw a few rough boards across the beams, placed piles of straw over them, laid down single planks to walk upon, and lo, it was a hospital at once.

There were six churches and they were all full, the barn-like place known as the Drill Room, all the private houses after their capacity, the shops and empty buildings, the school-houses – every inch of space and yet the cry was for more room.

We went about our work with pale faces and trembling hands, yet trying to appear composed for the sake of our patients, who were much excited. We could hear the incessant explosions of artillery, the shrieking whistles of the shells, and the sharper, deadlier more thrilling roll of musketry; while every now and then the echo of some charging cheer would come, borne by the wind, and as the human voice would pierce that demoniacal clangor we would catch out breath and listen, and try not to sob, and turn back to the forlorn hospitals, to the suffering at our feet and before our eyes while imagination fainted at the thought of those other scenes hidden from us beyond the Potomac.

Had Federal General George McClellan crossed the Potomac and pursued General Lee’s scattered and mauled army, as historians have much criticized him since for not doing, Shepherdstown would have likely suffered greater damage, but, as it was, shells landed in the yards of the Lees and Morgans and one or two even hit Shepherd’s new Town Hall, but were of little consequence.

Property Losses in New Orleans:

41_RD’s fine residence at 18 Bourbon Street
42_18 Bourbon Street in New Orleans
More invasive, improvised use was being made of RD’s fine residence at 18 Bourbon Street in New Orleans, causing his nephew to formally appeal to the Federal powers-that-be in early 1864. He wrote:

43_From Brig. General James Bowen
January 29, 1864
From Brig. General James Bowen
Provost Marshal General
Department of the Gulf.

Sir:
The undersigned acting as the duly authorized agent and attorney in fact of Rezin Davis Shepherd, formerly the State of Virginia, but for more than eight months past residing with his daughter Mrs. Gorham Brooks in the city of Boston and State of Massachusetts, respectfully represents: That the said Shepherd is a loyal citizen of the United States and the true and lawful owner of the Brick Dwelling No. 18 Bourbon Street between Canal and Custom House Streets in the City of New Orleans and also of all the furniture and contents thereof: that in the month of June, 1862 Col. Stafford without show of authority, placed in possession of said house and contents, a man by the name of Horton or Houghton, who has ever since occupied and now occupied and uses the same as a Boarding House, and who never has paid any rent or compensation there and continually refused to do so.

Under the circumstances, the undersigned respectfully appeals to you, General, for relief, and asks that the matter be referred to Capt. Edward Page and Thomas Tileston, or other of them for investigation and that the aforesaid premises and contents be restored to the possession of the owner without delay; Henry Shepherd Jr.

Like The Town Hall, the huge, magnificent Almshouse in New Orleans remained unfinished, to be hit by a worse fate. Shepherd was charged by Touro’s will to first put ,00 toward its construction, then be prepared to put more money into its construction- including even some of Shepherd’s own funds – as recipient of Touro’s residue.

44_occupied by detachments of the 2nd Maine Cavalry
45_The fire started
46_Baked beans fired the building
On September 1, 1865, at a time the Almshouse in New Orleans – still with an unfinished, floorless top floor – was occupied by detachments of the 2nd Maine Cavalry and Company K, First Louisiana Cavalry. A baking oven was in heavy use at one end of the building so that heat would be carried through a fissure in a ventilation system close by. The fire started in the rafters above the third floor. It was night-time with a high wind and no flooring yet laid for the third floor in that wing. Coals dripping from the fire then ignited tar on the lower walls. “Baked beans fired the building” said one from the 2nd Maine Cavalry. The building was uninsured. Just a few months later R. D. Shepherd died of typhoid fever, November 10, 1865, no longer the executor of the estate, leaving no philanthropist to help make up the loss.

Wrote the editors of the Times-Picayune in a long obituary:
In his native village he erected a splendid building, designed for a town hall, also a large academy, with beautiful grounds and a walk. He also deposited with the Mayor annually a large sum to buy fuel and provisions for the poor. He also erected the largest and most costly church in Jefferson County. Many other acts of public and private benevolence were performed by him in his quiet, furtive manner.

With war ended and when he was still healthy, RD had urged that his Town Hall become the County Court since the Charlestown courthouse was a battle-scarred ruin, especially from a shelling it took in the fall of 1863.

A Visitor Contemplates Charlestown’s Ruined Courthouse in mid-1865:

47_the court-house, where that mockery of justice was performed, was a ruin
48_Four massive white brick pillars, still standing, supported a riddled roof
A short walk up into the centre of the town took us to the scene of John Brown’s trial. It was a consolation to see that the jail had been laid in ashes, and that the court-house, where that mockery of justice was performed, was a ruin abandoned to rats and toads. Four massive white brick pillars, still standing, supported a riddled roof, through which God’s blue sky and gracious sunshine smiled. The main portion of the building had been literally torn to pieces. In the floor-less hall of justice rank weeds were growing.

49_Names of Union soldiers were scrawled along the walls
Names of Union soldiers were scrawled along the walls. No torch had been applied to the wood-work, but the work of destruction had been performed by the hands of hilarious soldier-boys ripping up floors and pulling down laths and joists to the tune of “John Brown,” the swelling melody of the song, and the accompaniment of crashing partitions, reminding the citizens, who thought to have destroyed the old hero, that his soul was marching on. It was also a consolation to know that the court-house and jail would probably never be rebuilt, the county-seat having been removed from Charlestown to Shepherdstown — “forever,” say the resolute loyal citizens of Jefferson County, who rose to vote it back again.

While RD’s nephew and agent, Henry Shepherd Jr. was in New Orleans during the war, minding the family interests, three of his brothers were at war. The eldest Rezin Davis, his older brother who had a young family

52_eldest Rezin Davis, his older brother who had a young family
since 1858, died of disease November 2, 1862 at his “river cottage” after imprisonment in the Old Capitol Prison for being an associate of Confederate spy, Redmond Burke. He left his widow, Elizabeth Boteler Stockton Shepherd, two children (Fannie and Alexandria) and a third (David) on the way. Probably first buried on his farm, Rezin Shepherd (a nephew of the patriarch) was reburied after peace came in the new Elmwood Cemetery. His site was joined by all his family as time unspooled.

53_twenty-five year-old Abraham
Henry Jr.’s next brother, twenty-five year-old Abraham, enlisted May 22nd, 1861, would move over to Co. F. of the 17th Virginia Cavalry, get wounded at the third battle of Winchester in September 19, 1864, and become a prisoner of war. But he survived the war and died many years later in 1907.

54_Henry Jr.’s younger brother, James Touro (Truro) Shepherd
Henry Jr.’s younger brother, James Touro (Truro) Shepherd, enlisted as a Private May 1st, 1861 in the 2nd Virginia Infantry. Like many, the rigors of marching under Gen. Stonewall Jackson proved an impetus to transfer out into a Cavalry regiment, and he joined Co. B of Gen. Stuart’s Horse Artillery under John Pelham, with a promotion to first lieutenant. His service record ends abruptly in the spring of 1862. The Shepherdstown Register in September, 1865 reported him having died in “Richmond City” in March, 1862. His marker dates his death as August 13, 1862, which may be the date of his re-internment into the family burial ground.

Two sons of James H. and his wife, Florence Hamtramck Shepherd were buried a few feet apart in the family burial ground on Shepherdstown’s New Street adjacent to the Episcopal rectory. Robert F. Shepherd, who joined Co. H, 2nd Va. Infantry, died May 4, 1862 of pneumonia.

Rezin Davis Shepherd was buried there too, in his own time.

He left all his fortune to his daughter, who, since 1855, had been a widow.

Wrote the Shepherdstown Register: A Large Estate – the late Rezin D. Shepherd left an estate valued at about ,500,000 all of which goes to his daughter, Mrs. Brooks of Boston. He was born in 1784 (on the lot where the court house would be built). In 1809 he went to New Orleans and engaged in the commission business until 1849 and was the executor of the estate of the late Judah Touro. Mr. Shepherd was formerly a merchant in this city, residing on High Street. He accumulated a very large property in New Orleans and was reputed to be one of the wealthiest men of that city. Upon the breaking out of the rebellion, he returned to Boston and resided for a short time with his daughter and sole heir, Mrs. Gorham Brooks, widow of a son of the late Peter C. Brooks. His estate on High Street was formerly, we believe the property of Samuel Dexter.

The Massachusetts Historical Society today displays a cannon donated by the family and acquired by RD – a smaller version of the one that so severely wounded RD’s friend, Judah Touro.

The visiting journalist Trowbridge was proven wrong – the county seat DID go back to the Charlestown Courthouse. Wrote the editors of the Charlestown-based newspaper, The Spirit of Jefferson, in 1894:

58_The Normal College building, formerly the town hall
The Normal College building, formerly the town hall, on Main Street, is a handsome structure, the gift of one of the Shepherd family, Rezin D. from which the town takes its name. You will remember that it was used as a court house since the war and the courts of Jefferson county were held there, one Judge Hall sitting on the bench. A political rape was perpetuated on Charlestown, the party in power, fitly termed radicals, thought they had a sure thing of it, built a jail and added a wing to either side of the town hall, but “the best laid schemes of mice and men gang af’t aglee.” The fellows that did all this mischief were turned down by the people and things took their normal shape and Charlestown was again the county seat.

Shepherd University began when the county seat of Jefferson County, West Virginia, was moved from Shepherdstown to Charles Town in July 1871. On February 27, 1872, the Legislature of West Virginia passed the following act: “That a branch of the State Normal School be and the same is hereby established at the building known as Shepherd College, in Shepherdstown, in the county of Jefferson.”

59_RD’s descendant, Shepherd Brooks
RD’s descendant, Shepherd Brooks, made it final when he deeded the property and building over to the School and a three-person board of trustees to maintain it.

As they say, settings reverse, the tide of life had gone out – and – came back in again.

Details, quoting from Smithsonian National Air and Space Museum | Curtiss P-40E Warhawk (Kittyhawk IA):

Whether known as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a successful, versatile fighter during the first half of World War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s "Flying Tigers" flew in China against the Japanese remain among the most popular airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the first American ace of World War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright built this airplane as Model 87-A3 and delivered it to Canada as a Kittyhawk I in 1941. It served until 1946 in No. 111 Squadron, Royal Canadian Air Force. U.S. Air Force personnel at Andrews Air Force Base restored it in 1975 to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Long Description:
Whether it was the Tomahawk, Warhawk, or Kittyhawk, the Curtiss P-40 was a successful and versatile fighter aircraft during the first half of World War II. The shark-mouthed Tomahawks that General Claire Chennault led against the Japanese remain among the most popular airplanes of the war. In the Phillipines, Lt. Boyd D. Wagner became the first American ace of World War II while flying a P-40E when he shot down six Japanese aircraft during mid-December 1941. P-40s were first-line Army Air Corps fighters at the start of the war but they soon gave way to more advanced designs such as the Republic P-47 Thunderbolt and the Lockheed P-38 Lightning (see NASM collection for both aircraft). The P-40 is not ranked among the best overall fighters of the war but it was a rugged, effective design available in large numbers early in the war when America and her allies urgently required them. The P-40 remained in production from 1939 to the end of 1944 and a total of 13, 737 were built.

Design engineer Dr. Donovan R. Berlin layed the foundation for the P-40 in 1935 when he designed the agile, but lightly-armed, P-36 fighter equipped with a radial, air-cooled engine. The Curtiss-Wright Corporation won a production contract for 210 P-36 airplanes in 1937-the largest Army airplane contract awarded since World War I. Worldwide, fighter aircraft designs matured rapidly during the late 1930s and it was soon obvious that the P-36 was no match for newer European designs. High altitude performance in particular became a priceless commodity. Berlin attempted to improve the P-36 by redesigning it in to accommodate a turbo-supercharged Allison V-1710-11 inline, liquid-cooled engine. The new aircraft was designated the XP-37 but proved unpopular with pilots. The turbo-supercharger was not reliable and Berlin had placed the cockpit too far back on the fuselage, restricting the view to the front of the fighter. Nonetheless, when the engine was not giving trouble, the more-streamlined XP-37 was much faster than the P-36.

Curtiss tried again in 1938. Berlin had modified another P-36 with a new Allison V-1710-19 engine. It was designated the XP-40 and first flew on October 14, 1938. The XP-40 looked promising and Curtiss offered it to Army Air Corps leaders who evaluated the airplane at Wright Field, Ohio, in 1939, along with several other fighter proposals. The P-40 won the competition, after some modifications, and Curtiss received an order for 540. At this time, the armament package consisted of two .50 caliber machine guns in the fuselage and four .30 caliber machine guns in the wings.

After production began in March 1940, France ordered 140 P-40s but the British took delivery of these airplanes when Paris surrendered. The British named the aircraft Tomahawks but found they performed poorly in high-altitude combat over northern Europe and relegated them to low-altitude operations in North Africa. The Russians bought more than 2,000 P-40s but details of their operational history remain obscure.

When the United States declared war, P-40s equipped many of the Army Air Corps’s front line fighter units. The plucky fighter eventually saw combat in almost every theater of operations being the most effective in the China-Burma-India (CBI) Theater. Of all the CBI groups that gained the most notoriety of the entire war, and remains to this day synonymous with the P-40, is the American Volunteer Group (AVG) or the Flying Tigers. The unit was organized after the Chinese gave former U. S. Army Air Corps Captain Claire Lee Chennault almost 9 million dollars in 1940 to buy aircraft and recruit pilots to fly against the Japanese. Chennault’s most important support within the Chinese government came from Madam Chiang Kai-shek, a Lt. Colonel in the Chinese Air Force and for a time, the service’s overall commander.

The money from China diverted an order placed by the British Royal Air Force for 100 Curtiss-Wright P-40B Tomahawks but buying airplanes was only one important step in creating a fighting air unit. Trained pilots were needed, and quickly, as tensions across the Pacific escalated. On April 15, 1941, President Franklin D. Roosevelt quietly signed an Executive Order permitting Chennault to recruit directly from the ranks of American military reserve pilots. Within a few months, 350 flyers joined from pursuit (fighter), bomber, and patrol squadrons. In all, about half the pilots in the Flying Tigers came from the U. S. Navy and Marine Corps while the Army Air Corps supplied one-third. Factory test pilots at Bell, Consolidated, and other companies, and commercial airline pilots, filled the remaining slots.

The Flying Tigers flew their first mission on December 20. The unit’s name was derived from the ferocious fangs and teeth painted on the nose of AVG P-40s at either side of the distinctive, large radiator air intake. The idea is said to originate from pictures in a magazine that showed Royal Air Force Tomahawks of No. 112 Squadron, operating in the western desert of North Africa, adorned with fangs and teeth painted around their air intakes. The Flying Tigers were the first real opposition the Japanese military encountered. In less than 7 months of action, AVG pilots destroyed about 115 Japanese aircraft and lost only 11 planes in air-to-air combat. The AVG disbanded on July 4, 1942, and its assets, including a few pilots, became a part of the U. S. Army Air Forces (AAF) 23rd Fighter Group in the newly activated 14th Air Force. Chennault, now a Brigadier General, assumed command of the 14th AF and by war’s end, the 23rd was one of the highest-scoring Army fighter groups.

As wartime experience in the P-40 mounted, Curtiss made many modifications. Engineers added armor plate, better self-sealing fuel tanks, and more powerful engines. They modified the cockpit to improve visibility and changed the armament package to six, wing-mounted, .50 caliber machine guns. The P-40E Kittyhawk was the first model with this gun package and it entered service in time to serve in the AVG. The last model produced in quantity was the P-40N, the lightest P-40 built in quantity, and much faster than previous models. Curtiss built a single P-40Q. It was the fastest P-40 to fly (679 kph/422 mph) but it could not match the performance of the P-47 Thunderbolt and the P-51 Mustang so Curtiss ended development of the P-40 series with this model. In addition to the AAF, many Allied nations bought and flew P-40s including England, France, China, Russia, Australia, New Zealand, Canada, South Africa, and Turkey.

The Smithsonian P-40E did not serve in the U. S. military. Curtiss-Wright built it in Buffalo, New York, as Model 87-A3 and delivered it to Canada as a Kittyhawk IA on March 11, 1941. It served in No. 111 Squadron, Royal Canadian Air Force (RCAF). When the Japanese navy moved to attack Midway, they sent a diversionary battle group to menace the Aleutian Islands. Canada moved No. 111 Squadron to Alaska to help defend the region. After the Japanese threat diminished, the unit returned to Canada and eventually transferred to England without its P-40s. The RCAF declared the NASM Kittyhawk IA surplus on July 27, 1946, and the aircraft eventually returned to the United States. It had several owners before ending up with the Explorer Scouts youth group in Meridian, Mississippi. During the early 1960s, the Smithsonian began searching for a P-40 with a documented history of service in the AVG but found none. In 1964, the Exchange Club in Meridian donated the Kittyhawk IA to the National Aeronautical Collection, in memory of Mr. Kellis Forbes, a local man devoted to Boys Club activities. A U. S. Air Force Reserve crew airlifted the fighter to Andrews Air Force Base, Maryland, on March 13, 1964. Andrews personnel restored the airplane in 1975 and painted it to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting from Wikipedia | Curtiss P-40 Warhawk:

The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including those of most Allied powers during World War II, and remained in front line service until the end of the war. It was the third most-produced American fighter, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation‘s main production facility at Buffalo, New York.

The P-40 design was a modification of the previous Curtiss P-36; this reduced development time and enabled a rapid entry into production and operational service.

Warhawk was the name the United States Army Air Corps adopted for all models, making it the official name in the United States for all P-40s. The British Commonwealth and Soviet air forces used the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

The P-40’s lack of a two-stage supercharger made it inferior to Luftwaffe fighters such as the Messerschmitt Bf 109 or the Focke-Wulf Fw 190 in high-altitude combat and it was rarely used in operations in Northwest Europe. Between 1941 and 1944, however, the P-40 played a critical role with Allied air forces in three major theaters: North Africa, the Southwest Pacific and China. It also had a significant role in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s performance at high altitudes was not as critical in those theaters, where it served as an air superiority fighter, bomber escort and fighter bomber.

P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, during June 1941. The Royal Air Force‘s No. 112 Squadron was among the first to operate Tomahawks, in North Africa, and the unit was the first to feature the "shark mouth" logo, copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. [N 1]

Although it gained a post-war reputation as a mediocre design, suitable only for close air support, more recent research including scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 offered the additional advantage of low cost, which kept it in production as a ground-attack fighter long after it was obsolete in the air superiority role.

As of 2008, 19 P-40s were airworthy.

Aluminum airframe and body with some fiberglass features; payload bay doors are graphite epoxy composite; thermal tiles are simulated (polyurethane foam) except for test samples of actual tiles and thermal blankets.

The first Space Shuttle orbiter, "Enterprise," is a full-scale test vehicle used for flights in the atmosphere and tests on the ground; it is not equipped for spaceflight. Although the airframe and flight control elements are like those of the Shuttles flown in space, this vehicle has no propulsion system and only simulated thermal tiles because these features were not needed for atmospheric and ground tests. "Enterprise" was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long approach-and-landing test flight program. Thereafter it was used for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred "Enterprise" to the Smithsonian Institution’s National Air and Space Museum.

Particulars, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in much more hostile airspace or with such comprehensive impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s efficiency and operational achievements placed it at the pinnacle of aviation technologies developments during the Cold War.

This Blackbird accrued about 2,800 hours of flight time during 24 years of active service with the U.S. Air Force. On its final flight, March six, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilometers (two,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane more than to the Smithsonian.

Long Description:
No reconnaissance aircraft in history has operated in much more hostile airspace or with such full impunity than the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird’s overall performance and operational achievements placed it at the pinnacle of aviation technology developments for the duration of the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a complete-blown crisis in the mid-1950s. U.S. military commanders desperately necessary precise assessments of Soviet worldwide military deployments, particularly close to the Iron Curtain. Lockheed Aircraft Corporation’s subsonic U-2 (see NASM collection) reconnaissance aircraft was an capable platform but the U. S. Air Force recognized that this relatively slow aircraft was currently vulnerable to Soviet interceptors. They also understood that the fast development of surface-to-air missile systems could place U-2 pilots at grave threat. The danger proved reality when a U-2 was shot down by a surface to air missile over the Soviet Union in 1960.

Lockheed’s 1st proposal for a new high speed, higher altitude, reconnaissance aircraft, to be capable of avoiding interceptors and missiles, centered on a design propelled by liquid hydrogen. This proved to be impracticable because of considerable fuel consumption. Lockheed then reconfigured the design for traditional fuels. This was feasible and the Central Intelligence Agency (CIA), already flying the Lockheed U-two, issued a production contract for an aircraft designated the A-12. Lockheed’s clandestine ‘Skunk Works’ division (headed by the gifted design engineer Clarence L. &quotKelly&quot Johnson) designed the A-12 to cruise at Mach 3.2 and fly properly above 18,288 m (60,000 feet). To meet these challenging needs, Lockheed engineers overcame several daunting technical challenges. Flying more than three times the speed of sound generates 316° C (600° F) temperatures on external aircraft surfaces, which are adequate to melt conventional aluminum airframes. The style team chose to make the jet’s external skin of titanium alloy to which shielded the internal aluminum airframe. Two standard, but very potent, afterburning turbine engines propelled this exceptional aircraft. These power plants had to operate across a huge speed envelope in flight, from a takeoff speed of 334 kph (207 mph) to far more than 3,540 kph (2,200 mph). To avoid supersonic shock waves from moving inside the engine intake causing flameouts, Johnson’s group had to design and style a complicated air intake and bypass technique for the engines.

Skunk Functions engineers also optimized the A-12 cross-section style to exhibit a low radar profile. Lockheed hoped to accomplish this by carefully shaping the airframe to reflect as tiny transmitted radar power (radio waves) as achievable, and by application of special paint created to absorb, rather than reflect, those waves. This remedy became 1 of the very first applications of stealth technologies, but it never totally met the design and style objectives.

Test pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, right after he became airborne accidentally for the duration of high-speed taxi trials. The airplane showed excellent guarantee but it necessary considerable technical refinement prior to the CIA could fly the first operational sortie on Could 31, 1967 – a surveillance flight over North Vietnam. A-12s, flown by CIA pilots, operated as element of the Air Force’s 1129th Special Activities Squadron beneath the &quotOxcart&quot system. Even though Lockheed continued to refine the A-12, the U. S. Air Force ordered an interceptor version of the aircraft designated the YF-12A. The Skunk Performs, nonetheless, proposed a &quotspecific mission&quot version configured to conduct post-nuclear strike reconnaissance. This program evolved into the USAF’s familiar SR-71.

Lockheed constructed fifteen A-12s, which includes a unique two-seat trainer version. Two A-12s had been modified to carry a particular reconnaissance drone, designated D-21. The modified A-12s were redesignated M-21s. These have been designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a pylon in between the rudders. The M-21 then hauled the drone aloft and launched it at speeds higher enough to ignite the drone’s ramjet motor. Lockheed also constructed 3 YF-12As but this variety in no way went into production. Two of the YF-12As crashed during testing. Only one survives and is on display at the USAF Museum in Dayton, Ohio. The aft section of 1 of the &quotwritten off&quot YF-12As which was later employed along with an SR-71A static test airframe to manufacture the sole SR-71C trainer. 1 SR-71 was lent to NASA and designated YF-12C. Which includes the SR-71C and two SR-71B pilot trainers, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Simply because of extreme operational fees, military strategists decided that the more capable USAF SR-71s should replace the CIA’s A-12s. These were retired in 1968 right after only one year of operational missions, mainly over southeast Asia. The Air Force’s 1st Strategic Reconnaissance Squadron (part of the 9th Strategic Reconnaissance Wing) took over the missions, flying the SR-71 beginning in the spring of 1968.

After the Air Force started to operate the SR-71, it acquired the official name Blackbird– for the particular black paint that covered the airplane. This paint was formulated to absorb radar signals, to radiate some of the tremendous airframe heat generated by air friction, and to camouflage the aircraft against the dark sky at high altitudes.

Experience gained from the A-12 system convinced the Air Force that flying the SR-71 safely necessary two crew members, a pilot and a Reconnaissance Systems Officer (RSO). The RSO operated with the wide array of monitoring and defensive systems installed on the airplane. This equipment integrated a sophisticated Electronic Counter Measures (ECM) method that could jam most acquisition and targeting radar. In addition to an array of advanced, high-resolution cameras, the aircraft could also carry gear developed to record the strength, frequency, and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was created to fly deep into hostile territory, avoiding interception with its tremendous speed and high altitude. It could operate safely at a maximum speed of Mach three.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth. The crew had to put on pressure suits equivalent to these worn by astronauts. These suits have been necessary to shield the crew in the event of sudden cabin stress loss whilst at operating altitudes.

To climb and cruise at supersonic speeds, the Blackbird’s Pratt &amp Whitney J-58 engines had been designed to operate continuously in afterburner. Whilst this would seem to dictate high fuel flows, the Blackbird in fact accomplished its greatest &quotgas mileage,&quot in terms of air nautical miles per pound of fuel burned, during the Mach 3+ cruise. A standard Blackbird reconnaissance flight may require many aerial refueling operations from an airborne tanker. Each time the SR-71 refueled, the crew had to descend to the tanker’s altitude, normally about six,000 m to 9,000 m (20,000 to 30,000 ft), and slow the airplane to subsonic speeds. As velocity decreased, so did frictional heat. This cooling impact caused the aircraft’s skin panels to shrink significantly, and those covering the fuel tanks contracted so much that fuel leaked, forming a distinctive vapor trail as the tanker topped off the Blackbird. As soon as the tanks had been filled, the jet’s crew disconnected from the tanker, relit the afterburners, and once again climbed to higher altitude.

Air Force pilots flew the SR-71 from Kadena AB, Japan, all through its operational career but other bases hosted Blackbird operations, as well. The 9th SRW sometimes deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were flown directly from Beale. The SR-71 did not start to operate in Europe till 1974, and then only temporarily. In 1982, when the U.S. Air Force based two aircraft at Royal Air Force Base Mildenhall to fly monitoring mission in Eastern Europe.

When the SR-71 became operational, orbiting reconnaissance satellites had currently replaced manned aircraft to collect intelligence from sites deep within Soviet territory. Satellites could not cover each geopolitical hotspot so the Blackbird remained a important tool for worldwide intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 supplied information that proved vital in formulating profitable U. S. foreign policy. Blackbird crews offered critical intelligence about the 1973 Yom Kippur War, the Israeli invasion of Lebanon and its aftermath, and pre- and post-strike imagery of the 1986 raid conducted by American air forces on Libya. In 1987, Kadena-based SR-71 crews flew a number of missions more than the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened industrial shipping and American escort vessels.

As the performance of space-based surveillance systems grew, along with the effectiveness of ground-primarily based air defense networks, the Air Force started to drop enthusiasm for the high-priced plan and the 9th SRW ceased SR-71 operations in January 1990. In spite of protests by military leaders, Congress revived the system in 1995. Continued wrangling more than operating budgets, even so, soon led to final termination. The National Aeronautics and Space Administration retained two SR-71As and the one SR-71B for higher-speed study projects and flew these airplanes until 1999.

On March six, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This unique airplane bore Air Force serial number 64-17972. Lt. Col. Ed Yeilding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington D.C. in 1 hour, four minutes, and 20 seconds, averaging a speed of 3,418 kph (two,124 mph). At the conclusion of the flight, ‘972 landed at Dulles International Airport and taxied into the custody of the Smithsonian’s National Air and Space Museum. At that time, Lt. Col. Vida had logged 1,392.7 hours of flight time in Blackbirds, far more than that of any other crewman.

This specific SR-71 was also flown by Tom Alison, a former National Air and Space Museum’s Chief of Collections Management. Flying with Detachment 1 at Kadena Air Force Base, Okinawa, Alison logged far more than a dozen ‘972 operational sorties. The aircraft spent twenty-four years in active Air Force service and accrued a total of two,801.1 hours of flight time.
