Ford LevaCar, the 1960 concept exhibit was destroyed in a fire, floated a few inches off the ground on three air jets, but only while tethered over a glass floor within the Ford Rotunda

Ford spent millions developing the Levacar Mach I . Though the tiny, single-passenger bubble was restricted to gliding around an indoor glass track, the Jetsons-styled coupe actually did levitate.

In the car above is Andrew Kucher, the VP of Ford Engineering and Research
