Project Blue Book records at the National Archives
The Air Force transferred its Blue Book files to the National Archives in 1976, where they're available on 94 rolls of microfilm (T-1206).
1976 CE · 38.99, -76.96 · status: official
The account
The collection covers Projects Sign, Grudge and Blue Book (1947–1969): 12,618 sightings, of which 701 stayed 'unidentified'. Witness names were removed before release. Separate rolls hold the photographs.
The sceptical view
The files record what the Air Force chose to log. By the Air Force's own regulations, cases with national-security implications could be handled outside Blue Book.
