We actually had a production flying car in 1950. Molt Taylor was actually making them on a small scale.
Powered flight and practical automobiles emerged at about the same time, and inventors have been trying to merge them ever since. Few have done so with the verve of Moulton Taylor, who founded Aerocar International in the late 1940s, a time when civil aviation was booming thanks to a new generation of pilots trained in World War II. Inspired by Robert Fulton Jr's Airphibian, the first road-able plane to be certificated by the Civil Aeronautics Administration, Taylor was determined to invent his own practical flying car.
