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.
Donald Howard Menzel
He was among the first prominent scientists to offer an opinion on the matter. One of Menzel's earliest public involvements in UFO matters was his appearance on a radio documentary directed and narrated by Edward R. Murrow in mid-1950. (Swords, 98)
