Euromast is an observation tower in Rotterdam, constructed among 1958 and 1960. It was constructed for the 1960 Floriade, and is a listed monument because 2010. The tower is a concrete structure with an internal diameter of 9 m (30 ft) and a wall thickness of 30 cm (12 in). For stability it is built on a concrete block of 1,900,000 kg (four,200,000 lb) so that the center of gravity is under ground. It has a observation platform 96 m (315 ft) above-ground and a restaurant. Initially 101 m (331 ft) in height it was the tallest creating in Rotterdam. It lost this position for a whilst, but regained it when the Space Tower was added to the top of the creating in 1970, providing an additional 85 m (279 ft).

Quoting Smithsonian National Air and Space Museum | Hawker Hurricane Mk. IIC:

Hawker Chief Designer Sydney Camm’s Hurricane ranks with the most important aircraft designs in military aviation history. Created in the late 1930s, when monoplanes have been regarded as unstable and too radical to be profitable, the Hurricane was the initial British monoplane fighter and the 1st British fighter to exceed 483 kilometers (300 miles) per hour in level flight. Hurricane pilots fought the Luftwaffe and helped win the Battle of Britain in the summer season of 1940.

This Mark IIC was built at the Langley factory, near what is now Heathrow Airport, early in 1944. It served as a training aircraft during the World War II in the Royal Air Force’s 41 OTU.

Quoting Smithsonian National Air and Space Museum | Northrop P-61C Black Widow:

The P-61 Black Widow was the 1st U.S. aircraft developed to find and destroy enemy aircraft at evening and in poor climate, a feat produced attainable by the use of on-board radar. The prototype 1st flew in 1942. P-61 combat operations started just soon after D-Day, June six, 1944, when Black Widows flew deep into German airspace, bombing and strafing trains and road visitors. Operations in the Pacific started at about the exact same time. By the finish of World War II, Black Widows had observed combat in every single theater and had destroyed 127 enemy aircraft and 18 German V-1 buzz bombs.

The Museum’s Black Widow, a P-61C-1-NO, was delivered to the Army Air Forces in July 1945. It participated in cold-climate tests, higher-altitude drop tests, and in the National Thunderstorm Project, for which the prime turret was removed to make room for thunderstorm monitoring gear.
