Flying saucer

Purported disk-shaped aircraft

A flying saucer, or flying disc, is a purported disc-shaped UFO. In science fiction, reported UFO sightings, and UFO conspiracy theories, they are typically piloted by nonhuman beings. The terms flying saucer and flying disc can be used generically for a mysterious flying object. The term was coined in 1947 but has gradually been supplanted since 1952 by the United States Air Force term unidentified flying object (UFO), the downside of which being that, according to the term, absolutely anything can be a UFO. Early reported sightings of flying saucers usually described them as silver or metallic, sometimes reported as covered with navigation lights or surrounded with a glowing light, hovering or moving rapidly, either alone or in tight formations with other similar craft, and exhibiting high maneuverability.
