Unidentified Flying Object

You may be looking for the comic story.

UFO was, during the 20th and 21st centuries, a human designation standing for Unidentified Flying Object. Many UFOs were believed by some of the general public, such as Eugene Jones and Maxwell Edison, to be alien spacecraft. Particularly in the 1950s and into the 1970s, the public often reported UFOs as flying saucers, crewed by "Martians".

Alien defence organisations such as UNIT and the Torchwood Institute and insiders like Henry van Statten knew that many UFOs did, as suspected, come from planets other than Earth.
