Flying saucer

A flying saucer (also referred to as a flying disc) is a descriptive term for a supposed type of flying craft having a disc or saucer-shaped body, commonly used generically to refer to an anomalous flying object. The term was coined in 1930 but has generally been supplanted since 1952 by the United States Air Force term unidentified flying objects or UFO's. Early reported sightings of unknown "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.

While disc-shaped flying objects have been interpreted as being sporadically recorded since the Middle Ages, the first recorded use of the term "flying saucer" for an unidentified flying object was to describe a probable meteor that fell over Texas and Oklahoma on June 17, 1930. "Some who saw the weird light described it as a huge comet, a flaming flying saucer, a great red glow, a ball of fire." The highly publicized sighting by Kenneth Arnold on June 24, 1947, resulted in the popularity of the term "flying saucer" by U.S. newspapers. Although Arnold never specifically used the term "flying saucer", he was quoted at the time saying the shape of the objects he saw was like a "saucer", "disc", or "pie-plate", and several years later added he had also said "the objects moved like saucers skipping across the water." Both the terms flying saucer and flying disc were used commonly and interchangeably in the media until the early 1950s.

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. A lot of sightings of the cigar-shaped UFO were reported following it. More recently, the flying saucer has been largely supplanted by other alleged UFO-related vehicles, such as the black triangle. The term UFO was, in fact, invented in 1952, to try to reflect the wider diversity of shapes being seen. However, unknown saucer-like objects are still reported, such as in the widely publicized 2006 sighting over Chicago-O'Hare airport.
