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.
Nazi UFOs
Similar sentiments regarding German technology resurfaced in 1947 with the first wave of flying saucer reports after Kenneth Arnold's widely reported close encounter with nine crescent-shaped objects moving at a high velocity. Personnel of Project Sign, the first U.S. Air Force UFO investigation group, noted that the advanced flying wing aeronautical designs of the German Horten brothers were similar to some UFO reports. In 1959, Captain Edward J. Ruppelt, the first head of Project Blue Book (Project Sign's follow-up investigation) wrote:
While these early speculations and reports were limited primarily to military personnel, the earliest assertion of German flying saucers in the mass media appears to have been an article which appeared in the Italian newspaper "Il Giornale d'Italia" in early 1950. Written by Professor Giuseppe Belluzzo, an Italian scientist and a former Italian Minister of National Economy under the Mussolini regime, it claimed that "types of flying discs were designed and studied in Germany and Italy as early as 1942". Belluzzo also expressed the opinion that "some great power is launching discs to study them".
