Info: Bill Horton's "wingless airplane". Bill entered into a partnership with Howard Hughes, and legal wrangling from that (still ongoing!) stopped all development of this plane.
"Sky Baby" the world's smallest homebuilt biplane, 1952. Made it in the "Guinness Book of World Records", but not practical for the homebuilt market and designer Ray Stits
donated it to the National Air and Space Museum.
-- the Fulton Airphibian, the first roadable aircraft (designed to be used as a car or an airplane) to be certificated by the Civil Aviation Administration.
-- XH-17 "Flying Crane", by Hughes aircraft. It still holds the record for the largest flying rotor system that ever flew. But was not practical for production.
