Operation Majestic-12 was established by special classified presidential order on September 24, 1947 at the recommendation of Secretary of Defense James Forrestal and Dr. Vannevar Bush, Chairman of the Joint Research and Development Board. The goal of the group was to exploit everything they could from recovered alien technology.
Buried in a super-secret "MAJIC EYES ONLY" classification that was above TOP SECRET long before the modern top secret codeword special access programs of today Major General Leslie R. Groves (who commanded the Manhattan Project to deliver the atomic bomb) kept just one copy of the details of crashed alien technology in his safe in Washington, D.C.
Ambitious, elite scientists such as Vannevar Bush, Albert Einstein, and Robert Oppenheimer, and career military people such as Hoyt Vandenberg, Roscoe Hillenkoetter, Leslie Groves, and George Marshall, along with a select cast of other experts, feverishly and secretively labored to understand the alien agenda, technology, and their implications.
Einstein and Oppenheimer were called in to give their opinion, drafting a six-page paper titled "Relationships With Inhabitants Of Celestial Bodies." They provided prophetic insight into our modern nuclear strategies and satellites, and expressed agitated urgency that an agreement be reached with the President so that scientists could proceed to study the alien technology.
The extraordinary recovery of fallen airborne objects in the state of New Mexico, between July 4 July 6, 1947, caused the Chief of Staff of the Army Air Forces Interplanetary Phenomena Unit, Scientific and Technical Branch, Counterintelligence Directorate to initiate a thorough investigation. The special unit was formed in 1942 in response to two crashes in the Los Angeles area in late February 1942. The draft summary report begins "At 2332 MST, 3 July 47, radar stations in east Texas and White Sands Proving Ground, N.M. tracked two unidentified aircraft until they both dropped off radar. Two crash sites have been located close to the WSPG. Site LZ-1 was located at a ranch near Corona, Approx. 75 miles northwest of the town of Roswell. Site LZ-2 was located approx. 20 miles southeast of the town of Socorro, at latitude 33-40-31 and longitude 106-28-29".
The first-ever-known UFO crash retrieval case occurred in 1941 in Cape Girardeau, Missouri. This crash kicked off early reverse-engineering work, but it did not create a unified intelligence effort to exploit possible technological gains apart from the Manhattan Project uses.
The debris from the primary field of the 1947 crash 20 miles southeast of Socorro, New Mexico was called ULAT-1 (Unidentified Lenticular Aerodyne Technology), and it excited metallurgists with its unheard-of tensile and shear strengths. The fusion nuclear (called neutronic at that time) engine used heavy water and deuterium with an oddly arranged series of coils, magnets, and electrodes descriptions that resemble the "cold fusion" studies of today.
Harry Truman kept the technical briefing documents of September 24, 1947 for further study, pondering the challenges of creating and funding a secret organization before the CIA existed (although the Central Intelligence Group or CIG did exist) and before there was a legal procedure of funding non-war operations.
In April 1954, a group of senior officers of the U.S. intelligence community and the Armed Forces gathered for one of the most secret and sensational briefings in history. The subject was Unidentified Flying Objects not just a discussion of sightings, but how to recover crashed UFOs, where to ship the parts, and how to deal with the occupants. For example, in the "Special Operations Manual (SOM1-01) Extraterrestrial Entities Technology Recovery and Disposal," MAJESTIC12 "red teams" mapped out UFO crash retrieval scenarios with special attention given to press blackouts, body packaging, and live alien transport, isolation, and custody.
