The cockpit of Rotar (The Roth Air Car) was a tight fit, especially for its creator Ed Roth. Powered by two Triumph motorcycle engines, and weighing 750 pounds, Rotar was able to hover several inches off the ground. A Roth Studios promotional postcard optimistically claimed "there is a remote possibility that this will be the first car to reach the MOON." (Collection of the Petersen Automotive Museum)
