Robert Sheaffer
The twentieth episode of the third season of the "X-Files" television series, entitled Jose Chung's From Outer Space, referenced Robert Sheaffer. The plot featured US Air Force test pilots, dressed as aliens, who flew a secret military aircraft designed to resemble a UFO. One pilot was named "Jacques Sheaffer" and the other "Robert Vallee". According to Sheaffer, Chris Carter, the creator of the X-Files series, decided to name the characters after ufologist Jacques Vallee, and debunker Sheaffer, as a joke. Sheaffer further states that "The M.P. [military policeman] who later arrested them (the test pilots) was Sergeant Hynek", a reference to prominent ufologist J. Allen Hynek.
