Majestic-12 (MJ-12) is said to be a secret group of 12 (some say 19) scientists, intelligence officers and high level government officials who were involved with researching UFOs and information pertaining to extraterrestrials. The group is said to have been created by President Harry Truman by executive order in 1947, possibly in response to the Roswell, New Mexico UFO incident.

A top secret meeting location was said to have been created in Maryland for the purpose of MJ-12 that was only accessible via air. Much of the funding for Majestic-12 came through illegal CIA activities such as the drug trade to keep the funding and project out of the eyes of the representatives in Congress.
