- Title Reference: An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon. The term "UFO" was officially created in 1953 by the United States Air Force to serve as a catch-all for all such reports.
