General Information
The United States Air Force retired to the custody of the National Archives its records on Project BLUE BOOK relating to the investigations of unidentified flying objects. Project BLUE BOOK has been declassified and the records are available for examination in our research room. The project closed in 1969 and we have no information on sightings after that date.
The National Archives has received numerous inquiries concerning documents identified as “MJ12” and “Briefing Document: Operation Majestic 12.” We have made extensive searches among the records in our custody of the U.S. Air Force and the Joint Chiefs of Staff to identify these documents. The Truman and Eisenhower Libraries have also searched their holdings for any references to, or copies of, the documents. In addition, the records of the National Security Council (NSC) for the Truman and Eisenhower Administrations are in the custody of the National Archives. Searches were made of the indexes to the NSC’s Policy Paper and Meeting Minute files under the subjects MJ-12, majestic, unidentified flying objects, UFO, flying saucers, extraterrestrial biological entities, and Aquarius. These searches were all negative except for a Memorandum for General Twining, from Robert Cutler, Special Assistant to the President, Subject: “NCS/MJ-12 Special Studies Project” dated July 14, 1954. The memorandum, one page, refers to a briefing to take place on July 16. The memorandum does not identify MJ-12 or the purpose of the briefing.
Project BLUE BOOK Reference Report
Textual records of Project BLUE BOOK (the documentation relating to investigations of unidentified flying objects), excluding names of people involved in the sightings, are now available for research in the National Archives Building. The records include approximately 2 cubic feet of unarranged project or administrative files, 37 cubic feet of case files in which individual sightings are arranged chronologically, and 3 cubic feet of records relating to the Office of Special Investigations (OSI), portions of which are arranged chronologically, by OSI district, and by overseas command. A cubic foot of records comprises about 2,000 pages. Finding aids for these records include a file list for the project files and an index to individual sightings, entered by date and location.
Access to BLUE BOOK textual records is using 94 rolls of 35mm microfilm (T-1206) in the National Archives Microfilm Reading Room. The first microfilm roll includes a list of contents for all of the rolls and the finding aids. Photographs scattered among the textual records have also been filmed separately on the last two rolls.
Motion picture film, sound recordings, and some still pictures are maintained by the Motion Picture & Sound & Video Branch (NNSM) and the Still Picture Branch (NNSP).

UFOs & PROJECT BLUE BOOK
On December 17, 1969, the Secretary of the Air Force announced the termination of Project BLUE BOOK, the Air Force program for the investigation of UFOS.
From 1947 to 1969, a total of 12, 618 sightings were reported to Project BLUE BOOK. Of these 701 remain “Unidentified.” The project was headquartered at Wright-Patterson Air Force Base, whose personnel no longer receive, document, or investigate UFO reports.
The decision to discontinue UFO investigations was based on an evaluation of a report prepared by the University of Colorado entitled, “Scientific Study of Unidentified Flying Objects;” a review of the University of Colorado’s report by the National Academy of Sciences; past UFO studies and Air Force experience investigating UFO reports during the 40s, ’50s, and ’60s.
As a result of these investigations and studies and experience gained from investigating UFO reports since 1948, the conclusions of Project BLUE BOOK are:(1) no UFO reported, investigated, and evaluated by the Air Force has ever given any indication of threat to our national security;(2) there has been no evidence submitted to or discovered by the Air Force that sightings categorized as “unidentified” represent technological developments or principles beyond the range of present-day scientific knowledge, and (3) there has been no evidence indicating that sightings categorized as “unidentified” are extraterrestrial vehicles.
With the termination of Project BLUE BOOK, the Air Force regulations establishing and controlling the program for investigating and analyzing UFOs were rescinded. Documentation regarding the former BLUE BOOK investigation has been permanently transferred to the Military Reference Branch, National Archives and Records Administration, Washington, DC 20408, and is available for public review and analysis.
Since Project BLUE BOOK was closed, nothing has happened to indicate that the Air Force ought to resume investigating UFOS. Because of the considerable cost to the Air Force in the past, and the tight funding of Air Force needs today, there is no likelihood the Air Force will become involved with the UFO investigation again.
There are a number of universities and professional scientific organizations, such as the American Association for the Advancement of Science, which have considered UFO phenomena during periodic meetings and seminars. In addition, a list of private organizations interested in aerial phenomena may be found in Gayle’s Encyclopedia of Associations (edition 8, vol-. 1, pp. 432-433). Such timely review of the situation by private groups ensures that sound evidence will not be overlooked by the scientific community.
A person calling the base to report a UFO is advised to contact a private or professional organization (as mentioned above) or to contact a local law enforcement agency if the caller feels his or her public safety is endangered.
Periodically, it is erroneously stated that the remains of extraterrestrial visitors are or have been stored at Wright-Patterson AFB. There are not now nor ever have been, any extraterrestrial visitors or equipment on Wright-Patterson Air Force Base.
