Glenn Curtiss gets credit for the first flying car with his 1917 Autoplane that married a flivver (resembling a Model T) to a biplane–make that triplane. Aerofiles.com found the photos and drawings. The car, patented in 1919, was capable of short hops–bunny hops, to be exact. It tried but never achieved sustained flight. By the way, if you think the old Curtiss company is long gone, meet today’s Curtiss-Wright Corporation, the same company formed in 1929 with the merger of 12 Wright and Curtiss affiliated companies. It’s still there, and still in aviation.
