Smokey Stover who it is agreed by most 415th members gave the "foo fighters" their name. The phrase foo fighter, also taken from Holman's strip, was used by Allied aircraft pilots in World War II to describe various unidentified flying objects or mysterious aerial phenomena seen in the skies over both the European and Pacific Theaters of Operations. Though foo fighter initially described a type of UFO reported and named by the 415th Squadron, the term was also commonly used to mean any UFO sighting from that period. Foo Fighters is also the name of a rock band, first heard in 1995.
Unidentified flying object Dr Edgar Mitchell claimed that he knew of senior government employees who had been involved in "close encounters" and because of this he has no doubt that aliens have visited Earth. While technically a "UFO" refers to any unidentified flying object, in modern popular culture the term UFO has generally become synonymous with alien spacecraft; however, the term ETV (ExtraTerrestrial Vehicle) is sometimes used to separate this explanation of UFOs from totally earthbound explanations. Besides anecdotal visual sightings, reports sometimes include claims of other kinds of evidence, including cases studied by the military and various government agencies of different countries
