"Nightmare at 20,000 Feet" is the third episode of the fifth season American television anthology series The Twilight Zone, based on the short story of the same name by Richard Matheson, first published in the short story anthology Alone by Night (1961). It originally aired on October 11, 1963 and is one of the most well-known and frequently referenced episodes of the series. The story follows a passenger on an airline flight who notices a hideous creature trying to sabotage the aircraft during flight.
