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.
UFO conspiracy theory
In 1976 a televised documentary report "UFOS: It Has Begun" written by Robert Emenegger was presented by Rod Serling, Burgess Meredith and José Ferrer. Some sequences were recreated based upon the statements of eyewitness observers, together with the findings and conclusions of governmental civil and military investigations. The documentary uses a hypothetical UFO landing at Holloman AFB as a backdrop.
