de Havilland Comet
The de Havilland Comet was a source of pride because it was the first passenger airliner in the history of the planet. This year, 1952, was the beginning of a brand new age. There were a lot of interesting qualities about it, but there were also a lot of problems with it. The model could not be redesigned in time to prevent it from being involved in a deadly accident, despite the efforts of the engineers employed.
Devil’s Hovercraft
A United States Army engineer came up with the Devil’s Hoverbike in the middle of the 1950s. For the pilot to be able to move the plane, he needed to support his feet. There were difficulties to solve here. It seems likely that he was responsible for the crash of the airplane. People came up with the idea of hoverboards as a result.
