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

Regardless of whether known as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a productive, versatile fighter during the initial half of Globe War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s &quotFlying Tigers&quot flew in China against the Japanese remain among the most common airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the very first American ace of Planet War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright constructed 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.

Specifics, 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 total 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 in the course of the Cold War.

This Blackbird accrued about two,800 hours of flight time throughout 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, four minutes, and 20 seconds, averaging three,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.

Transferred from the United States Air Force.

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

By V-J Day, September two, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design and style allowed ground clearance for the huge, 3-bladed Hamilton Regular Hydromatic propeller, which spanned much more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the biggest and a single of the most strong 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-help fighter assigned to the USS Essex in July 1944.

Blue Angels Tigers have been the longest serving Tigers. Its a pretty tiny airplane but technologies was moving so speedily that supersonic in level flight, four X 20mm cannon, and in-flight refueling capability weren’t enough to make a Visual Flight Guidelines (VFR – ie not evening/all weather, no radar in the nose…) fighter extremely interesting to the Navy. For a complete redesign that was initially pitched as a derivative of the F9F Cougar/Panther, the TIger is a fairly neat piece of function.
But with Vought’s F8U-1 Crusader and McDonnell F3H-1 Demon carrying some radar and promising much more, along with much more internal volume for fuel, the Tiger was good, but not very great sufficient.
The massive fin and rudder had been direct final results of the F-100C crash that killed test pilot George Welch- North American doubled the size of the F-100D’s fin and rudder. Grumman revised their prototype really swiftly when word got back from Edwards AFB, where both the F9F-11 and F-one hundred had been getting tested. Soon the F9F-11 was the F-11F-1 and a really modern-sized fin and rudder graced every Tiger that flew. The Tiger was also region ruled from the onset – taking a lesson from the tough luck of the Lockheed YP-90 and Convair YF-102, which looked great but could not get past the drag boost of the &quotsound barrier&quot.
It all seems so incredible, Vought, Lockheed, Grumman, North American, McDonnell, Convair, not to overlook Douglas, Republic, (and dark-horses Northrup, Boeing and Martin) all creating single-seat jet fighters in the USA, although AVRO Canada was conceiving the CF-105 to follow the CF-100s. AVRO, de Havilland, Bristol, Hawker, Supermarine (and other individuals?) have been designing single-seat fighters in the UK NORD and Dassault were lighting up French skies, and Bill Lear Jr was leading the design and style of an indigenous *Swiss* single seat jet. MiG, Yak, Sukoi and Tupolev had been all at it in the Soviet Union also.
Jet engine power and economy were nothing like today- they were heavy, weak, and blew fuel out the tail-pipe as if it expense

An Odd Sense of Tidiness?

Image by Alan Stanton
Beer can on the railings of Chestnuts Park. 30 January 2013.

Our buddy Lix Ixer and I have attempted to envision what may well be in people’s minds when they litter. Especially when an individual seems to take slightly more care than just dropping or tossing away a drink can.

On Harringay Online internet site Liz recommended a list of nine &quottypes&quot of litterers. Study the full version here. The drink-can spiker may belong to Liz’s very first variety.

Liz Ixer’s List of &quottypes&quot of litterers.

1 &quotThere is often an odd sense of ‘tidiness’ about some litterers: these are the ones who meticulously pop their cans and paper down the backs of utility cabinets, balance them on walls or tuck them down the side of planters. A small bit of them knows what they are performing is wrong and they hope by getting ‘tidy’, they offend less (perhaps there is a distant memory of a mum or dad telling them to put it in the bin).&quot

two &quotFervent believers in the Haringey litter gods who should be propitiated with frequent offerings&quot.
3 &quotThose for whom littering is a civil liberties situation. You don’t have the right to inform them what to do with their lives, which includes what they do with their litter.&quot
four &quotSweet old ladies who cautiously sweep their front step and garden every single morning and then open the front gate and whoosh it all into the street. &quot
5 &quotThe group who believe they are keeping men and women in employment by spreading the litter far and wide.&quot
six &quotThe bone idle litterer . . . who can see a litter bin within a stride but can not be arsed to go 1 step out of their way to deposit their waste.&quot
7 &quotCar diners . . . who park up, acquire a fast meals delicacy from the several fine establishments in the area, return to their automobile, fill up on grease and carbs then pile the packaging into the gutter prior to driving off.&quot
eight &quotThe litter deniers …. have two excuses for themselves: ‘my one particular bottle/can/wrapper will not hurt as there is a bag awaiting collection anyway’ or ‘I would use a bin but they are as well manky/complete/hard to use’,&quot
9 &quotThe inebriated. After six lagers for £5, I doubt you could see the bin, let alone navigate your way to it.&quot

The aim is that by by understanding people’s behaviour it may possibly be changed. &quotWe require&quot, says Liz Ixer, &quotto be far more inventive and inventive in how we get people to be far more accountable.&quot

Liz mentions past public education campaigns. Also some current initiatives. Examples incorporate: a lot more incentives for people to recycle decreasing the use of plastic bags higher engagement with little quick meals outlets to assist clean up and with businesses to decrease packaging.

.ten a gallon, which it most likely did. But they went faster the propeller engines. Compare the subterfuge and trickery all of these airframe firms of the 1950s were applying to the jet fighters of right now – tail surfaces are are nonetheless sharply swept, but wings got a lot straighter, since yet another ton or two of thrust is easier to make than a thin, tapering, swept structure that is stiff enough to do the job and cheap adequate to construct.
But the F11F or MiG-19, F-one hundred, F-8 Crusader, even the F-4 Phantom look like they’re going twice the speed of an F/A-18 or even the supercruise-capable F-22. (Supersonic without having afterburner).
