One out of eight Americans claims to have seen a UFO, including Sammy Hagar and Muhammad Ali. And that is just one of the juicy tidbits of information that pop up during The Truth Behind UFOs. In the vein of VH1's Pop Up Video series, NGC offers pop-culture factoids while charting the rise of UFO sightings from the 1940s to the present day. Experts investigate a UFO sighting in Connecticut, meet a man who claims to have flown an actual flying saucer and analyze eye-witness video. Will their research finally uncover the truth behind aliens? Probably not, but viewers will learn that "Foo Fighters" is more than a band name; the term originally referred to small, round objects that followed Allied bombers in Germany.
