 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.
