The Aerodrome
Samuel Pierpont, the scientist, and inventor created a plane in 1901 that was able to fly for nearly over a mile. After this, he created the first-ever manner power flight. It did very well with its 52 hp radial and a successful power-to-weight ratio, however, it was very unsuccessful and landed in the Potomac River twice.
The McDonnell XF-85 Goblin
The reason this plane was created was to be a parasite fighter. This means that this small plane is attached to a larger plane, that ejects while it’s in the air to attack any other enemy flights. Unfortunately, this plan did not work out so well and giant enemy planes ended up taking over.
