The Wright Flyer
The Smithsonian says this about the Wright Flyer: “the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard.” In addition, it was unable to last even one minute in the air and was extremely difficult to navigate. On the 17th of December in 1903, this plane attempted to fly four times, but that was it.
The Harrier Jump Jet
Taking inspiration from the British Navy, the Soviet Union made a plane which they called Yakovlev Yak-38. Unfortunately, the Soviet version of the British plane didn’t live up to its standards. When it was hot outside, the plane could only stay airborne for 15 minutes. In better weather, the aircraft could still only fly about 800 miles when it did not even have any weapons on board.
