Majestic 12, also known as MJ-12 for short, is a purported organization that appears in UFO conspiracy theories. The organization is claimed to be the code name of an alleged secret committee of scientists, military leaders, and government officials, formed in 1947 by an executive order by U.S. President Harry S. Truman to facilitate the recovery and investigation of alien spacecraft. The concept originated in a series of supposedly leaked secret government documents first circulated by ufologists in 1984. The FBI claims the documents are bogus and others claim the FBI claim is a cover-up.
The following individuals were described in the Majestic 12 documents as “designated members” of Majestic 12
- Lloyd Berkner Detlev Bronk Vannevar Bush James Forrestal (Chairman)
- Gordon Gray Roscoe H. Hillenkoetter Jerome Clarke Hunsaker Donald H. Menzel
- Robert M. Montague Sidney Souers Nathan F. Twining Hoyt Vandenberg
Related to the alleged actions taken by MJ12 is a document titled SMO1-01 (a UFO Protocol Manual). The complete version of this manual can be seen at: https://www.specialoperationsmanual.com/the-manual/
