Reading edition · 8 September 2026
The same source-linked index, available without JavaScript.
This index supplies individual record descriptions and dated release entries for the 2026 publication effort. It is useful for following a database item to its context and source material. Compare a recording’s observation year with the later date on which the government released it.
Individual release descriptions and supporting documents
A central index to annual assessments, historical reporting, congressional testimony, briefing slides, and press materials. It offers a practical route to the office’s published positions over time. Use each document’s reporting interval and release date to avoid combining incompatible totals or outdated assessments.
Annual reports, hearings, statements, and briefings
AARO publishes recordings with case descriptions and assessments, including resolved and unresolved reports. The index connects sensor imagery to its analytic context.
Official recordings and case assessments
The portal gathers supporting information papers and records, including materials analysis and historical program documents. It also connects readers to NASA and NARA resources. These papers serve different purposes, so a laboratory result, archival proposal, and agency explanation should be read as distinct forms of evidence.
Technical papers, materials analysis, and historical records
For 2 June 2024–30 May 2025, AARO received 319 reports and resolved 114 of those plus 256 older cases. Resolved cases had ordinary explanations.
Reporting interval ends May 2025
The introduced bill proposes ending AARO, transferring its functions, and amending related statutes. This is the introduced text of a proposal, not evidence that the office has been terminated. Its conditional instructions should not be presented as current operational facts or enacted requirements.
Introduced bill text; proposal, not enacted text
The department announced a second tranche of UAP materials following the May launch of its release database. The announcement points readers to the official portal for the records. Its date identifies publication of the tranche, not when every underlying observation occurred.
Second release tranche; use portal release filter R02
The third release announcement documents another installment in the government’s UAP publication effort and directs readers to the official database. Consult the individual files for their originating agency, event date, and context; the tranche’s release date is not a common date for its observations.
Third release tranche; use portal release filter R03
The fourth official release notice marks a further installment of public UAP records. It is an access and publication milestone rather than an analytic finding. The linked database provides the associated documents and media, whose observation dates and evidentiary quality vary by item.
Fourth release tranche; use portal release filter R04
The fifth release notice confirms a further set of UAP files was made public on 7 August 2026 and points to the government database. This is the latest tranche verified for this edition. Individual records require separate reading to understand their dates, provenance, and limitations.
Fifth release tranche; use portal release filter R05
PURSUE provides searchable government UAP releases with agency and tranche filters. Its files have different observation dates and evidentiary limits; publication does not establish an extraterrestrial explanation.
Government release database
A representative asks the Defence Ministry about a publicly reported cooperation arrangement involving CRIDOVNI and United States agencies, including equipment, costs, data access, and oversight. The record documents questions presented to government, not confirmation that the reported agreement was concluded.
Three-page official Spanish parliamentary request, No. 5073 / C2171/2026.
A dated entry in SEFAA’s resolved-case series supplies the July 2026 compilation. It provides a recent example of the authority’s continuing public reporting. The publication month and the dates of individual observations should be read separately.
Spanish monthly publication page; use its linked or embedded material for individual case details.
The collection index links agency transfers and digital records in the National Archives Catalog. Listed contributors include FAA, NRC, ODNI, OSD, NSA, State, FBI, and Air Force. Additions arrive over time, so this portal is a continuing access point rather than a completed government-wide inventory.
Rolling agency transfers under FY2024 NDAA
Enacted Public Law 119-60, sections 1671–1673, addresses briefings on NORAD and NORTHCOM UAP intercepts, removes a duplicative reporting requirement, clarifies agency data availability to AARO, and requires an accounting of classification guides. These are the adopted provisions, distinct from proposed disclosure amendments.
Enacted law; sections 1671–1673
The declassification task force heard from Jeffrey Nuccetelli, Alexandro Wiggins, George Knapp, Dylan Borland, and Joe Spielberger. Its page preserves witness documents and video on disclosure and reporting protections. Accounts and allegations remain distinguishable from independent confirmation of the events described.
Witness statements and hearing video
The federal review examines public UAP reporting and offers fourteen recommendations for coordination, transparency, data quality, and scientific participation. Recommendations are not automatically implemented policy.
Public reporting review and Canadian history
The sponsor announced submission of a UAP disclosure amendment to the FY2026 defense authorization bill. This entry records a legislative proposal and its stated disclosure aims. A sponsor’s announcement is not an enacted statute; compare any claimed requirement against the final public law.
Proposed amendment announcement; not an enactment record
NARA explains the collection’s statutory scope, how agencies identify and transfer digital records, and how public access is provided. It distinguishes the new collection from older UFO records already held across other record groups. Public availability remains subject to review and applicable disclosure restrictions.
Collection scope, transfer procedures, and public access
AARO assesses historical investigations and concealed-program allegations. It reports no verified extraterrestrial technology in the reviewed material; its methods, evidence, and limits are available for examination.
Historical investigations and allegations
The 2024 annual report presents the Argentine identification centre’s case studies with images and explanatory comparisons. It allows readers to inspect how candidate causes are evaluated, instead of relying on a short description of an apparently unusual object.
98-page Spanish PDF; year denotes the report series, not a verified day of publication.
The assessment covers reports from 1 May 2023 through 1 June 2024, including older events newly submitted. It describes 757 incoming reports, resolved ordinary objects, and cases awaiting more data. Its collection patterns and reporting sources are essential context for interpreting the figures.
1 May 2023–1 June 2024, plus earlier reports
The hearing page provides statements from Tim Gallaudet, Luis Elizondo, Michael Gold, and Michael Shellenberger, plus video of the proceedings. Topics include government transparency, research, and program allegations. Publication in a congressional record documents what witnesses said rather than establishing every allegation.
Witness statements and hearing video
Memorandum AC 04.2025 directed agencies to transfer publicly releasable UAP records identified by 20 October 2024 no later than 30 September 2025. It specifies digital copies, metadata, and treatment of redacted records while encouraging transfers throughout the period.
Agency instructions implementing FY2024 NDAA
The committee’s official page links its public hearing with AARO director Jon Kosloski and supporting documents. The session addressed the office’s activities and assessments. The page identifies this as an open/closed hearing, so publicly accessible materials do not represent any classified session.
Public hearing and supporting documents
Published in January 2023, this annual assessment explains growth in reporting and initial characterization of additional incidents. It distinguishes reporting totals from resolved objects and notes collection bias. The title’s year is the reporting edition, not the public release year.
2022 reporting edition; released January 2023
The report covers 31 August 2022 through 30 April 2023 and earlier reports not previously included. It describes 291 additional reports, reporting biases, and developing analytic procedures. Totals reflect information received during a defined interval rather than a census of all unidentified objects.
31 August 2022–30 April 2023, plus earlier reports
Enacted Public Law 118-31, sections 1841–1843, established a UAP records collection and agency review, transfer, and disclosure requirements. The law also sets grounds for postponing disclosure. Read the enacted provisions themselves rather than treating earlier, broader disclosure proposals as the final law.
Enacted law; sections 1841–1843, 44 U.S.C. 2107 note
Official hearing materials include testimony from Ryan Graves, David Fravor, and David Grusch on encounters, reporting practices, and government-program allegations. The record makes their statements accessible in context; firsthand observation, secondhand information, and independently established findings require separate evaluation.
Witness statements and hearing video
NASA’s study recommends improved calibration, metadata, collection, and scientific analysis. It outlines future research rather than identifying every historical sighting.
Independent study recommendations
The Senate’s hearing page preserves the public session on AARO’s mission, activities, oversight, and budget. It provides access to the official hearing record and supporting materials. Public testimony should be read alongside the published analyses and annual assessments it discusses.
Public component of an open/closed hearing
The establishment announcement explains how AARO expanded the earlier AOIMSG remit to airborne, submerged, space, and transmedium observations. It links the organizing memoranda and identifies the office’s reporting, collection, analysis, and science responsibilities. The underlying direction was issued on 15 July.
Establishment memoranda and announcement
Enacted Public Law 117-263 includes authorized UAP reporting procedures in section 1673 and revisions to AARO in section 6802. The provisions address protected reporting, office duties, and oversight. Statutory references to alleged materials or programs are not findings that those allegations are true.
Enacted law; sections 1673, 6802–6803
The official transcript records questions to defense and naval-intelligence officials about UAP reporting, incidents, and analytic limitations. It preserves the public portion of the hearing, including discussion of sensor imagery. A transcript records statements and does not independently verify every claim.
Public hearing transcript; 53 pages
The museum revisits Kenneth Arnold’s report near Mount Rainier and its role in the rapid spread of flying saucer stories. It provides historical context for a foundational sighting without treating the reported objects as an identified type of extraterrestrial vehicle.
1947 sighting and public terminology
NASA’s study archive links its statement of task, team appointments, public meeting, briefings, and final recommendations. Its focus is the scientific quality and availability of UAP data, with methods for improving future observation and analysis rather than reconstructing alleged spacecraft.
2022–2023 study materials and public meeting
The department directed establishment of the Airborne Object Identification and Management Synchronization Group as successor to the Navy task force. Its remit focused on objects in special-use airspace, reporting coordination, flight safety, and national security, with an executive oversight council.
Organizational transition in November 2021
Enacted Public Law 117-81, section 1683, required a UAP office, coordinated reporting and analysis, and reports to Congress. The historical statutory text helps explain the transition from temporary task forces toward a formal office. Later laws amended these duties.
Enacted law; section 1683, 50 U.S.C. 3373
ODNI reviews 144 government reports, chiefly from 2004–2021, describing data gaps, possible explanations, and flight-safety concerns.
Historical reporting sample
The information-access authority considered an unanswered request for Air Force UFO records. Its ruling called for disclosure except for information properly classified under the applicable rules and rejected blanket classification without the required justification. It illustrates a concrete obstacle to public access.
Three-page Spanish ruling; not the requested CRIDOVNI case files or proof that all files were released.
The Pentagon authorized publication of three Navy recordings previously circulating online. Its statement authenticates their Navy provenance and explains the release review. The recordings concern November 2004 and January 2015 observations; publication in 2020 is a separate event.
Three Navy recordings; statement dated 2020
Official announcement of the Navy-led UAP Task Force, approved on 4 August 2020. It describes a national-security mission to detect, analyze, and catalog reports. This documents an organizational decision, without identifying the causes of the phenomena being reported.
Task Force approval and mission
The Air Force’s identification centre describes its remit and provides annual case-resolution reports. It investigates documented observations to identify their causes, and explains why original visual evidence and accurate witness descriptions matter. Earlier reports from the predecessor commission are also linked.
Official Spanish portal with annual reports for 2015–2025; also documents CEFAE’s 2011 creation.
An archival overview traces the successive Air Force projects and explains the continuing public interest in their records. It places the investigation in its historical setting and points readers toward surviving reports. The article is retrospective context rather than a new assessment of sightings.
U.S. Air Force investigation programs, 1947–1969
The National Archives outlines how UFO reports entered Australian government files, including the 1954 Sea Fury account and Frederick Valentich’s disappearance. It describes the RAAF’s eventual withdrawal from investigating sightings and provides historical context for the surviving archival record.
Official archive essay; original files require separate catalogue research.
Chile’s civil aviation authority provides case publications, educational material, and a reporting route. The resolved-case archive is organized by year, with monthly compilations in recent years. The archive records assessed observations rather than a catalogue of authenticated anomalous aircraft.
Spanish site with annual case categories from 2018 through 2026 and links to supporting publications.
CIA history examines questionnaires, photography, expert consultation, and evidence testing, using Socorro, Tremonton, and the Robertson Panel as examples.
Historical investigation methods
Historian David Clarke’s archive-hosted briefing identifies government file series, policy changes, and release history, with references for tracing the overview into original documents.
British government research guide
The final tranche’s guide points to policy correspondence, sighting records, and the closure of the MOD UFO desk. Its selected highlights help readers navigate the much larger files without confusing a memorable witness account with an official conclusion.
12-page PDF describing selected files from the 2013 transfer; not a complete case index.
The National Library catalogue identifies the Defence Force publication containing UFO files prepared for public release. Its bibliographic record preserves the official publisher and file-volume references, helping researchers distinguish the government release from later compilations circulated by other websites.
Catalogue record for the 2010 release; this link is not a complete online full-text archive.
This Air Force administrative order defines the recording, cataloguing, and transfer of UFO reports to the national archive. It assigns responsibilities to COMDABRA and CENDOC. The document concerns handling information; it does not endorse a particular explanation for the sightings.
Government-hosted reproduction of the official gazette; the order is on PDF page 1. Published 10 August 2010.
A contemporary program briefing describes funding, the research task, contract administration, and technical deliverables. It records the 2008 appropriation context behind AAWSAP. This is evidence of a funded research effort; the briefing does not establish recovered nonhuman vehicles or operational exotic propulsion.
Program scope, funding, and deliverables
The released package includes Senator Harry Reid’s request to place the aerospace effort under special access protection and the department’s review. The review found no justification for that protection. Its attachments document the request, research deliverables, and response rather than an approved recovery program.
AAWSAP/AATIP correspondence and classification review
DIA organizes released material on advanced aerospace research, program briefs, technical papers, and associated correspondence. Its guide explicitly identifies an AAWSAP/AATIP section. Read contract objectives separately from speculative research topics; commissioning a paper does not demonstrate that its proposed technology was built.
AAWSAP, AATIP, and related released records
Fravor’s congressional statement recounts his visual encounter and footage obtained later by another crew. This firsthand account does not provide a complete public sensor dataset.
Nimitz testimony about November 2004
Gerald Haines reviews the CIA’s involvement in UFO investigations, intelligence concerns, the Robertson Panel, reconnaissance aircraft, and later disclosure disputes. The article provides citations to internal memoranda and other records. It is an agency historian’s interpretation of a complex archival record.
Intelligence history, 1947–1990
Annual PDF tables list reported sightings with dates, times, locations, and brief descriptions. They provide a compact way to explore the MOD’s reporting record. An entry documents a report received; it is not a finding that an unusual vehicle existed.
Thirteen annual PDFs covering 1997–2009, linked directly from the government publication page.
GAO documents its search across government holdings for records concerning the 1947 Roswell event. It identifies surviving contemporary records and discusses missing or destroyed administrative material. The report concerns record preservation and search results; missing files do not independently establish an extraterrestrial recovery.
NSIAD-95-187; government record search
The Air Force attributes the 1947 debris to MOGUL balloon research and discusses later occupant allegations separately. These are distinct historical findings.
Debris and later body allegations
The National Archives catalogs the FAA’s information releases concerning Japan Airlines Flight 1628. This series is a route to the agency’s surviving record of the Alaska report. Consult the catalog description and available files to distinguish crew observations, radar information, and subsequent interpretations.
FAA series; National Archives Identifier 733667
A government retrospective describes multiple luminous-object reports, radar detections, and fighter launches during the 1986 episode commonly called the Official UFO Night. It establishes an official account of the response; the retrospective is not a complete public reconstruction of sensor performance.
English government article published 20 May 2022, referring to events on 19 May 1986.
Transport Canada explains the aviation occurrence system used to receive, review, and publish safety information. The linked CADORS service is broader than UFO research. Records are preliminary and can change when additional information or corrections arrive.

France’s space agency publishes anonymized observation reports and investigation results. The archive distinguishes explained cases, probable explanations, reports lacking enough information, and cases still unexplained after investigation. Its categories describe an assessment, not the origin of a craft.
Public case search, maps, classifications, and attached documents; French is the principal language.
GEIPAN traces its institutional predecessors, public-information mission, and online case publication, while explaining anonymity and the distinction between missing information and unexplained observations.
GEPAN, SEPRA, and GEIPAN
NASA’s annual historical chronology records contemporary debate over whether the agency should resume UFO investigations. The volume combines agency actions with attributed press coverage. Its dated entries are useful context, but a summarized newspaper opinion should not be mistaken for a new scientific finding.
Carter-era debate within a broader annual chronology
NSA publishes a Joint Chiefs of Staff record concerning the reported encounter over Iran on 19 September 1976. It is a U.S. government record of an overseas event. Read the reporting chain and statements carefully before treating described performance or equipment problems as measured findings.
U.S. reporting about an Iranian encounter
The aviation authority traces its reporting effort from a meteorological-office commission to CEFAA and then SEFAA. The history identifies dated administrative changes and explains the office’s connection to aviation operations and its reliance on audiovisual evidence for investigations.
Spanish institutional history; linked case publications provide the investigative material.
The House Committee on Science and Astronautics convened a public symposium on UFOs. Its official transcript preserves scientific arguments and testimony for direct reading. The participants’ views should be evaluated individually; inclusion in a congressional volume does not make every claim a congressional finding.
Scientific testimony and debate
The university describes the Air Force-sponsored Condon study and its surviving research collection, including documents, notes, journals, and film. The institutional overview explains why the study was commissioned and summarizes its conclusions. Access to original archival items may require contacting the university.
Scientific Study of Unidentified Flying Objects and research files
This file preserves Ford’s public requests for congressional consideration of UFO reports and correspondence about the Air Force’s response. It also includes material on the University of Colorado study. These contemporary statements help explain the political setting of the 1966 hearings.
Congressional pressure and the Colorado study
The official hearing record preserves the House’s examination of UFO investigations in April 1966. Read the transcript for the questions asked, the officials’ responses, and the limits of their evidence. Testimony describes positions and statements made at the hearing, not universal agreement.
House oversight of Air Force investigations
The Defence Virtual Library provides eighty declassified files concerning reports involving Air Force personnel or equipment. The collection includes summaries, conclusions, witness interviews, and supporting material. It spans incidents across Spanish airspace and retains redactions protecting witnesses and reporting officers.
About 1,900 scanned pages; incidents from 1962–1995. Declassification began in 1991; physical consultation copies followed in 1992.
The Air Force museum documents the Canadian-built Avrocar and its U.S. military development history. Photographs and technical notes show a real disc-shaped experimental aircraft with serious stability limits. Its existence establishes this particular human aircraft, not an explanation for every saucer report.
U.S.–Canadian experimental vertical-flight aircraft
A security officer’s report records an investigation of a light observed near a nuclear test site. It compares witness accounts and candidate explanations, while acknowledging uncertainty about distance and source. The archive presents both the original pages and a readable transcription.
Two-page report dated 24 July about the 15 July sighting; images and transcript available.
NARA presents historical Blue Book material and catalog links for the Washington sighting wave, including a contemporary illustration and witness questionnaires.
Washington reports and Blue Book administration
The national archive describes its Air Force-origin UFO collection, including reports, forms, correspondence, photographs, drawings, audio, video, and press clippings. Its introduction explains that OVNI means an object not immediately identified and does not itself imply an extraterrestrial origin.
Official introduction links to SIAN, the archive catalogue. Its collection totals and date range describe the guide’s historical snapshot.
The FBI presents the 1950 memo and explicitly describes it as an indirect claim that the Bureau did not investigate. This context is essential when reading assertions about recovered saucers and occupants. The document’s existence does not establish the events it repeats.
A frequently misrepresented 1950 memorandum
A starting point for locating Ministry of Defence UFO reports and correspondence in the British government archive. Follow the catalogue references to individual files rather than treating the guide as a complete, searchable transcript of every historical report.
Guide to digital records and catalogue searches; individual catalogue entries specify download and reading-room access.
The CIA reading room provides document search and historical collections, including UFO-related material. Use names, dates, and document identifiers to locate individual records. Some files preserve foreign reporting or outside claims, so distinguish who wrote a document from the agency that retained it.
CIA public historical and FOIA records
The federal archive brings together UFO correspondence, reports, memoranda, and procedures from National Defence, Transport, the National Research Council, and the RCMP. The guide describes approximately 9,500 digitized documents accumulated from 1947 through the early 1980s.
Date and location searches can miss undated or imprecisely indexed records. Search multiple terms and originating agencies.
NARA provides catalog metadata and bulk files for digitized UFO collections, including Blue Book case files, artifacts, and related material. These downloads are substantially larger than individual documents. Availability follows digitization; the index is not a claim that every government record is public.
Digitized historical collections and newer UAP transfers
The FBI Vault provides released files concerning UFO reports and the Bureau’s correspondence about them. These records are useful for following how information reached investigators and other agencies. A report in an FBI file is not, by itself, a verified FBI conclusion.
Released UFO correspondence and reports
A guide connecting Air Force, FAA, NASA, CIA, defense, and other holdings to their catalog records. It includes textual files, photographs, sound, and moving images. Catalog descriptions explain provenance, while individual entries indicate whether digital copies are available to read.
Cross-agency archival discovery
The NSA’s UFO collection connects readers to released historical documents, including reporting, correspondence, and other retained material. Many items are scans with limited legibility. Authorship and context vary: a publication or report held by NSA is not automatically an NSA finding.
Declassified UFO-related holdings
NARA organizes UFO-related presidential holdings by library and connects readers to catalog entries. The material includes correspondence and policy-related records, with digitized copies where available. A letter received by an administration documents communication; it does not automatically represent an administration’s finding.
Presidential correspondence and administrative records
NARA explains access to historical Air Force UFO files, preserves the closure statement, and discusses alleged MJ-12 documents. Custody does not authenticate their claims.
Air Force files and reference reports
Selected public records and official collection access points. Some holdings are undigitized, redacted, classified, or available only by request. A released document can contain unverified claims. Follow collection links for broader available holdings.
