De Havilland Comet
De Havilland Comet was the very first commercial jet airliner to be made. It was designed and manufactured by de Havilland. Thousands of people were fascinated by the airliner. Well, their fascinations turned into disappointments when the airliner performed underwhelmingly.

It seemed like all of their efforts were just not enough – despite all the enhancements made with the airliner, it still performed in a very underwhelming way.
The Devil’s Hoverbike
The Devil’s Hoverbike was an aircraft that was designed for the use of the U.S. Army. It was launched in the middle of the 1950s. You might be thinking if this aircraft has something to do with hoverboards – yes, the Devil’s Hoverbike was the thing that inspired people to create hoverboards. Back in the 50s, the pilots, who would fly the aircraft, had something to balance their feet on to make the aircraft move. Well, if you would think of it, that was a challenging task – maybe that was one of the factors that made this aircraft end up being a colossal failure.
