Archivist note

This page, published by the National Archives and Records Administration (NARA) under Military Records Research > Air Force Records, is the finding-aid and reference entry point for Project BLUE BOOK, the U.S. Air Force program that investigated reports of unidentified flying objects. According to the archived page, the Air Force retired its Project BLUE BOOK records to NARA custody; the project closed in 1969, and the records have been declassified and made available for examination. The page states that the textual records (with names of sighting witnesses excluded) comprise approximately 2 cubic feet of project or administrative files, 37 cubic feet of case files arranged chronologically by individual sighting, and 3 cubic feet of records relating to the Office of Special Investigations (OSI). It notes that a cubic foot of records comprises about 2,000 pages, and that the finding aids include a file list for the project files and an index to individual sightings entered by date and location.

The page further records that access to the BLUE BOOK textual records is provided through 94 rolls of 35mm microfilm (publication T-1206), with the first roll listing the contents of all rolls and the finding aids, and photographs scattered among the textual records filmed separately on the last two rolls; related motion picture film, sound recordings, and some still pictures are held by separate NARA branches. The page also reproduces a U.S. Air Force Fact Sheet stating that from 1947 to 1969 a total of 12,618 sightings were reported to Project BLUE BOOK, of which 701 remain categorized as “unidentified,” and that the Air Force concluded no investigated sighting indicated a threat to national security, evidence of technology beyond present-day scientific knowledge, or an extraterrestrial origin. This index records only what the cited NARA page and its Wayback snapshot state; it is link-only, is not an agency publication, and endorses no conclusion beyond the official source.
