UFOs

A UFO is an unidentified flying object. UFOs have been sighted throughout history and around the world (as well as in outer space by astronauts). While the vast majority of UFO sightings are explainable (identified flying objects, IFOs), a small number remain unidentified. UFOs are also a cultural phenomenon that has captured the imagination of many people, and visiting sites associated in history or the popular imagination with UFOs can make for a fun vacation.
