Provenance
An uncited entry cannot exist in this archive — by construction, every sighting and every case reference points into this registry. Where the same event surfaces in several sources, the references are linked on its case page rather than duplicated in the log.
A civilian reporting center operating a public hotline and web intake since 1974. The archive's largest source, in two tranches: 80,332 geocoded reports from the public log (1906–2014), and 52,484 further reports through 2023 carrying NUFORC's own per-report ids and its annotations — 'Starlink - Certain' and kin — recorded here as the dispositions the center itself gave.
The most influential civilian body of the Blue Book era, chaired by Maj. Donald Keyhoe, whose case files pressed Congress toward hearings. Its directory survives online.
The largest civilian investigation body, fielding trained investigators since 1969. Its case management system is member-gated; entries here cite its published findings.
Australia's national archive, holding the RAAF unusual aerial sightings files and the Department of Transport accident file on the Valentich disappearance, radio transcript included.
The Ministry of Defence's UFO desk, whose files (1950–2009) sit at the National Archives. This archive carries the desk's 2,729 published sighting listings, 1997–2009, extracted from the gov.uk annual reports (Crown copyright, Open Government Licence).
Canada's national archive, holding the RCMP, RCC and Department of National Defence files on Canadian incidents — including the Shag Harbour file, in which the military's own log eliminated every conventional candidate.
France's official UAP study group inside the national space agency — the longest-running government investigation still open. This archive carries its full published case base of 3,381 cases (1937 to the present) with GEIPAN's own A–D classifications recorded as given, its coordinates, a link to each case file, and — from its witness-testimony export — observation times and reported forms.
Air traffic control transcripts, radar data, and administrative records touching pilot and controller reports, released on request.
Documents freed from the Department of Defense and the service branches under the Freedom of Information Act — memoranda, videos, intelligence reports, and message traffic.
The Air Force's UFO investigation, 1952–1969, with predecessors Sign (1947) and Grudge (1949). 12,618 sightings investigated; 701 remained unidentified at closure. This archive carries the ~585 unknowns compiled from the uncensored files by Don Berliner (Fund for UFO Research), as mirrored by NICAP — each with the disposition the Air Force itself gave: unidentified.
Brazil's national archive, holding the Força Aérea Brasileira's released UFO records — including the Operação Prato files from the 1977 Colares wave.
The Pentagon's standing UAP office since 2022, publishing case resolution reports, historical record reviews, and annual assessments to Congress.
The Air Force–funded academic study whose 1968 report ended Blue Book. Its conclusion was negative; roughly a third of its own case studies remained unexplained.
Reporting contemporaneous with an event — the first draft, cited with date and outlet, and weighed as such.
Witness reports filed directly with this archive. Held as-reported, reviewed before publication, and never edited beyond formatting.
On file: NUFORC's public log through 2023 in two tranches — the second carrying the center's own per-report annotations as dispositions as given; Project Blue Book's own unexplained cases; the UK Ministry of Defence desk's published listings, 1997–2009; and GEIPAN's complete official case base, 1937 to the present, with its A–D classifications recorded as given — including the 106 cases France left grade D, unidentified after investigation. In preparation: the full 12,618-case Blue Book records via the National Archives, NUFORC 2024 onward, and AARO's case resolution reports as released. MUFON's case management system is member-gated; its published findings are cited on case pages while a data arrangement is explored. Government tranches arrive through Aletheca, the house FOIA instrument, so each document carries the request that produced it.
