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.
Kenneth Arnold UFO sighting
The most famous UFO event during this period was the Roswell UFO incident, the alleged military recovery of a crashed flying disk, the story of which broke on July 8, 1947. To calm rising public concern, this and other cases were debunked by the military in succeeding days as mistaken sightings of weather balloons. Just before the Roswell story came out, the Army Air Forces in Washington issued a press statement saying they had the matter under investigation and had decided the flying discs definitely were "not" "secret bacteriological weapons designed by some foreign power", "new-type army rockets", or "space ships".
