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.
Flight Path (UFO)
"Flight Path" is the fifteenth episode aired of the first series of "UFO" - a 1970 British television science fiction series about an alien invasion of Earth. The screenplay, originally entitled "The Sun Always Rises", was written by Ian Scott Stewart and the director was Ken Turner. The episode was filmed between 26 May to 5 June, 1969 and aired on the ATV Midlands on 20 January, 1971. Though shown as the fifteenth episode, it was actually the third to have been filmed.
