Clip from the grooviest Sci-fi TV series ever, U.F.O. This particular episode was released in 1970, back in the Golden age of model based SFX.
The Interceptors are each armed with one nuclear tipped missile. So even if they miss, the blast could take out whatever is in its radius. The Interceptors were supposed to have a close ranged cannon armament but were never depicted in film.
The purple hair wigs were supposed to be antistatic protection. Strangely, it doesn't apply to men.
The concept air defense ground vehicles with SAMs were surprisingly realistic. They remind me of Strela-10s, which in real life were introduced a few years after this episode aired, and would have been in product development when this was shown.
The blonde next to Ed Straker and no. 2 in command is played by Wendy Ventham. In real life she is Benedict Cumberbatch's mum. Obviously Dr. Strange did not inherit her good looks.
After the Apollo 11 landings and the showing of 2001: A Space Odyssey, Science Fiction entered into an era of realism and feasible loving portrayals of technology. This era ended with the first Star Wars movie was shown in 1977.
The next clip is a British missile destroyer engaging a UFO. It's butt was saved by a SHADO submarine launched fighter. The HMS Hampshire D06 is a real life ship.
