A term used for objects that people can't tell what it really is. They are believed to carry aliens and monsters of other worlds.

The term 'Unidentified Flying Object' is a contradiction because the moment you see the object, it is identified. Therefore the proper term *should* be 'Incorrectly Identified Flying Object'
