The file contains a letter dated November 15, 1991, from Harry B. Brandon, III, Acting Assistant Director, Intelligence Division, to Commander, Office of Special Investigations, Dept. of the Air Force, Bolling Air Force Base, in Washington, D.C.
The subject is "Possible Unauthorized Disclosure of Classified Information Relating to "Operation MAJESTIC 12" and notes:
"Our Bureau recently recovered what may possibly be a classified document, dated November 18, 1952, relating to 'OPERATION MAJESTIC 12.'... It is noted that although this document may represent some type of hoax, it is our responsibility to insure that all incidents involving mishandling of classified data receive adequate investigative attention. Therefore, we request that your agency attempt to ascertain the originator and/or the current classification of the enclosed document. Your cooperation in this matter is appreciated."
We note here that the USAF Office of Special Investigations (AFOSI) was once again handed the responsibility for determining whether or not the MJ-12 documents were faked. AFOSI had previously advised the FBI that the MJ-12 document was fabricated, on November 30, 1988.
