The special effects are corny when compared to what we have now but the models for the show included a lot of concepts which were quite interesting for their time: a sub-launched interceptor, a moonbase, an orbital unmanned computer complex and lunar fighters. The story line of a secret organization using high-tech equipment to fight off an alien invasion (which is admittedly pretty small) is a great one to watch. The music and the "futuristic" costumes are added bonuses.I've enjoyed watching episodes of UFO just as much now as I did when I was a kid.
