UFO (TV series)
A single season of 26 episodes (including the pilot) was filmed over the course of more than a year; a five-month production break was caused by the closure of MGM-British Studios in Borehamwood, where the show was initially made. Production then moved to Pinewood Studios in Buckinghamshire. "UFO" was first broadcast in the UK and Canada in 1970, and in US syndication over the next two years.
The UFO Incident
The film aired two weeks before the Travis Walton UFO incident on November 5, 1975 which lead cognitive psychologist Susan Clancy to argue that this film influenced Travis Walton to present his own alleged abduction story.
