Storyline

In 1980, the Earth is threatened by an alien race who kidnap and kill humans and use them for body parts. A highly secret military organization is set up in the hope of defending the Earth from this alien threat. This organization is named SHADO (Supreme Headquarters Alien Defence Organization) and operates from a secret location beneath a film studio. They also operate a fleet of submarines and have a base on the moon as well as an early warning satellite that detects inbound UFOs. UFOs can be destroyed in space by Interceptors which are launched from Moonbase. If one gets through it can be attacked in the Earth's atmosphere by a high altitude aircraft launched from one of the submarines. If a UFO also avoids this and manages to land it can be tracked and destroyed by a number of Mobiles (armored vehicles) which are deployed throughout the world.

Trivia

In this series, the term "U.F.O." is usually not "spelled out". Most often, it is pronounced as a word: "you-foh." Only automated systems like the voice of the computer on the interlink satellite pronounce it "you-eff-oh". See more »

Goofs

When the alien is being taken down the corridor to the operating room, his eyes are open. Then, while on the operating table, the doctor removes the white plastic protective shells covering them. See more »

First introduction to sci-fi as a kid
13 February 2000 | by See all my reviews

I must have been 8 or 9 when I first saw it on TV in Los Angeles in the early 1970s. It was the show that seeded my love for science fiction a couple years before I was introduced to Star Trek. Granted, I didn't understand all of the plot lines, but I loved the miniatures, the special effects, and especially the purple hair of the moonbase crew. The theme is also rather catchy tune as a good theme should be. I'm happy to see that they're available on video and I will be ordering the set.
