The Sperry UFO case was a sighting of an Unidentified Flying Object by the captain, Willis Sperry, and other crew of an American Airlines DC-6 airborne near Mount Vernon, Maryland on 29 May 1950.
Media exposure of the case helped to establish a popular perception of UFOs being reported by "credible" witnesses such as airline pilots; Sperry was interviewed for several newspapers and was later featured in Clarence Greene's 1956 semi-documentary film Unidentified Flying Objects: The true story of flying saucers.[1]
^Willis Sperry was an experienced and respected pilot with a very wide flying experience, including the first (and only) attempt to deliver mail by towed glider, which took place in 1935 (see Glines, C. The Saga of the Air Mail, Ayer, 1980, ISBN 0405122136, pp.143-44)
