A UFO is an unidentified flying object. The first known reported sighting of a UFO was in the Roman Republic around 74 BC by a Roman army named Plutarch. Around 1951, Captain Edward J. Ruppelt was the director of Project Blue Book- the Air Force's official UFO investigation agency. Captain Edward J. Ruppelt was said to have created the name "UFO" to replace the words "flying saucers" sometime between 1951- 1953. UFO has now entered into common usage as well as the term Ufology, or the study of UFOs, and ufologists, or one who studies UFOs.

Descriptions of UFOs have differed around the world. Some have described it as "V-shaped," "saucer- shaped," "large, circular spinning white lights," "orange," "blue," etc. UFOs have been spotted in many different countries including: United States, United Kingdom, Australia, Russia, China, Canada, and Malaysia. 

In 1986, John Callahan, the Division Chief of the Accidents and Investigations Branch of the FAA, witnessed a UFO following a Japanese Airlines 747 flight for about 30 minutes. He was involved in a meeting that took place with people from the CIA, the FAA, and Reagan's scientific study team, who all alledgedly know about this sighting but refuse to talk about it. All the people involved in this meeting were sworn to not speak about it or acknowledge that it even happened. The government is said to be "covering up" the sighting as to not cause panic or fear among citizens.
