1970-UFO

This British series set in the futuristic year of 1980 sports the same funky fashions and look as Space:1999. The reason is they were both created and produced by Gerry and Sylvia Anderson; the husband/wife creative TV team behind Supercar, Thunderbirds, Captain Scarlet, and Terrahawks.
In 1970 UFO interest was still high and there were a number of TV series and documentaries based on them. Believed to be a threat to Earth, world governments unite and form SHADO (Supreme Headquarters, Alien Defense Organization)! Establishing bases and the Earth and the Moon, SHADO wages a secret battle against alien invaders as it attempts to discover who they are, where they come from, and what they want.
