 The term "flying saucer" quickly became deeply ingrained in the English vernacular.A Gallup poll from August 1947 found that 90% had heard about the mysterious flying saucers or flying discs, and a 1950 Gallup poll found that 94% of those polled had heard the term, easily beating out all other mentioned commonly used terms in the news such as "Cold War", "universal military training", and "bookie".In addition to the extraterrestrial hypothesis, a variety of possible explanations for flying saucers have been put forward.
