This flying automobile is probably the only real transformer in existence: The Aerocar, a machine that actually flies and can be legally driven on a highway. Built by Moulton B. Taylor in 1956 and powered by a Lycoming 160HP engine, you only have to attach the folded wings, tail, and propeller to explore the skies at 165mph. Don't believe it? The FAA does, and you only need $3.5 to buy and enjoy one.
