  • Flying saucer is the name given to a type of unidentified flying object (UFO) with a disc- or saucer-shaped body, usually described as silver or metallic, occasionally reported as covered with running 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.

    Although disc-shaped flying objects have been interpreted as recorded occasionally since the Middle Ages, the first highly publicized sighting by Kenneth Arnold in June 1947 resulted in the creation of the term. Arnold's sighting was followed by thousands of similar sightings across the world. Such sightings were once very common, to such an extent that "flying saucer" was a synonym for UFO through the 1960s before it began to fall out of favor. However, the term is still often used generically for any UFO.
