"GIMBAL" Pentagon UFO video, January 2015
An unidentified flying object (UFO) is an object or phenomenon seen in the sky but not yet identified or explained. The term was coined when United States Air Force (USAF) investigations into flying saucers found too broad a range of shapes reported to consider them all saucers or discs. UFOs are also known as unidentified aerial phenomena or unidentified anomalous phenomena (UAPs). Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.
