A tragic coincidence connected with this episode: at one point Sheckly deliberately walks toward a moving propeller blade. The episode's director, Boris Sagal, would be killed in 1981 when he accidentally walked into a helicopter's moving blades.
The characters all concluded that there is no way possible that an airplane could simply land itself. However, several years earlier in Missouri in 1957, a US Air Force DC-3 - the same type as used in the show - ran out of fuel while carrying people, who all bailed out to safety. The plane glided itself, landing on an empty cornfield, intact.
The exterior shots and hangar scenes were filmed at Santa Monica Airport in California. All other scenes were filmed on an MGM sound stage.
The FAA is referred to on at least two occasions as the Federal Aviation Agency, its correct name in 1961. The designation was changed in 1966 to the modern day Federal Aviation Administration.
One of the aircraft tail numbers mentioned N67588 was an actual C47, that first flew in 1944, and crash landed in 1988.
