The Starship
While everyone expected the Starship to be one of the best planes created, it certainly was not. While many thought it would be flawless, it was slow and challenging to fly. Back in 1989, 53 were made but not many were sold.
The Hiller VZ-1
In action, this plane was terrible, so we hope that the plan was a bit better. The plane has no gears, and the pilot is supposed to steer using his body weight. The plane could only reach 16 miles per hour and it was hated by most people.
