De Havilland Comet
It is a shame that the De Havilland Comet was such a failure in the end, as it did have some redeeming qualities, even if it did become the benchmark for aircraft failures. Its designers gave it their all, but it still could not avoid being an explosive waste.

The Devil’s Hoverbike
The 50s, as mentioned before, were a highly novel and quirky time for American army engineering. Hoverboards were invented then, as the single-manned chopper airplane which supposedly would allow soldiers to glide behind enemy lines. This may have been a cool design if any small misstep on the part of the pilot resulted in them being dismembered by the massive helicopter blades.
