Reading paths: Curated step-by-step routes through the archive
Foundations
-
A practical guide to navigating declassified U.S. government UAP records: understanding metadata, agency conclusions, status terminology, and the difference between a raw report and an assessed finding.
-
A guide to Record Group 615 (RG 615), the Unidentified Anomalous Phenomena Records Collection at the U.S. National Archives — its legal authority under the 2024 NDAA, the agencies whose records it holds, how it differs from the historical Project Blue Book records, and how to browse it in the National Archives Catalog.
-
A chronological overview of official U.S. government efforts to investigate unidentified flying objects and unidentified anomalous phenomena, from Project Sign in 1948 through Project Blue Book, the Condon Report, the UAP Task Force, and AARO.
-
An introduction to the All-domain Anomaly Resolution Office (AARO), the U.S. Department of Defense office established in 2022 to investigate unidentified anomalous phenomena (UAP), including its mission and the official records and reports it publishes.
-
An introduction to PURSUE — the Presidential Unsealing and Reporting System for UAP Encounters — the U.S. Department of War's government-wide UAP records and imagery release portal at war.gov/ufo: what it is, what has been released, and how this archive preserves and links to the files.
Evaluating sources
-
An introduction to using the Freedom of Information Act to request U.S. government UAP records, with guidance on which agencies hold relevant materials, where public reading rooms already exist, and how separate declassification mechanisms work.
-
An information-literacy guide to distinguishing primary sources (agency records, sensor data) from secondary sources (news, documentaries, social media) when evaluating claims about UAP, with a worked example using a publicly released case resolution report.
Cases & reports
-
A neutral explainer of the three U.S. Navy videos — FLIR (the 2004 Nimitz 'Tic Tac'), Gimbal, and GoFast (2015) — that the Department of Defense officially released in 2020, including how they became public and where the official records are held.
-
A neutral summary of what official U.S. government reports — the 1994–1995 GAO audit and the U.S. Air Force's 1994 and 1997 Roswell Reports — concluded about the 1947 events near Roswell, New Mexico, attributing the debris to Project Mogul and later accounts of bodies to test dummies.
-
An explanation of what the All-domain Anomaly Resolution Office (AARO) means by “case resolution” — how it distinguishes reported from assessed behavior, accounts for motion parallax and wind, and states confidence levels — and why resolution does not always mean a definitive identification.
-
A neutral overview of the U.S. government's recent UAP reporting — the 2021 ODNI preliminary assessment and the consolidated annual reports from ODNI and the Department of Defense — and their consistent finding that most cases lack sufficient data to resolve and that none has been confirmed as extraterrestrial technology.
