//Unidentified flying object (commonly abbreviated as UFO or U.F.O.) is the popular term for any apparent aerial phenomenon whose cause cannot be identified. The term Unidentified Flying Object has been in use by the United States Air Force from at least as early as February 1948  where it was defined in terms of descriptive characteristics such as shape, speed and manoeuvrability. //
