Unidentified Flying Objects (UFO) phenomenon has for a long time remained a folklore to many people. A UFO is an unusual sighting in the sky that is not readily identifiable to the observer with certainty as any known object.

The following are the top ten most common UFO sightings that have been reported since World War II.
