An early effort at disc-shaped design, the 'umbrella plane' of inventor Chance Vought. Aviation has advanced not only on its successes, but by learning from its failures.

Whatever this design's merits may be, they lie more in the quantity of fabric and the quality of the joinery than in any sound application of aerodynamic principles.

The aircraft, as far as we know, went nowhere; but Vought himself went on to produce a famous line of aircraft in the U.S.A.
