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.
Conflict (UFO)
"Conflict" is the fourth episode aired of the first series of "UFO" - a 1970 British television science fiction series about an alien invasion of Earth. Ruric Powell wrote the screenplay and it was directed by Ken Turner. The episode, initially titled "Ambush", was filmed between 2 July to 14 July, 1969 and aired on the ATV Midlands network on 7 October, 1970. Though shown as the fourth episode, it was actually the sixth to have been filmed.
