U.F.O. was a British series by Gerry Anderson. He was famous for creating 'Supermarionation'. It was a puppet, or rather marionette, animation. Stingray and Thunderbirds are two that I recall. U.F.O. was quite short-lived, but long enough for me to get a dinky-toy of one of the vehicles at Harrods during a trip to England. I do remember seeing the episode with Colonel Paul Foster (Billington) in the sauna. It was on CBC TV - up in Northern Ontario - in the early 1970s. Needless to say, my 7-year-old mind was transfixed by all that fur... I do recall an absolute thrill, but naught to do about it. I was just seven after all.
