80 Years of UAP Records

What this timeline shows

The PURSUE files span eight decades of U.S. government documentation of UAP encounters. The chronological view groups them by year and decade, with the agency that submitted each file shown as a color-coded label. Clicking any entry opens the file's dedicated page with the released summary, the rubric score, the source link to war.gov, and the SHA-256 hash for byte-level verification.

The earliest cluster - 1947 through 1968 - is dominated by the FBI's central case file 62-HQ-83894, which aggregates 18 PDFs of investigative records, eyewitness testimonies, and public reports the Bureau received during the period. The case file spans 21 years and is the longest-running single investigative record in the disclosure.

The 1965-1973 NASA cluster contains the Gemini 7 air-to-ground audio from December 1965 (the highest-scoring file in the archive, covered in our Borman Incident deep dive), the Apollo 12 lunar-surface photographs and transcript from November 1969, the Apollo 17 transcripts and triangular-formation image from December 1972, and Skylab crew debriefings from 1973-74.

The 2013-2026 modern cluster is the largest single block by file count: U.S. military mission reports and AARO unresolved UAP videos submitted by CENTCOM, Indo-Pacom, and other commands. The 27-file score-66 tier - the densest cluster in the archive - is concentrated in this period. See our AARO Unresolved UAP deep dive for the geographic and sensor breakdown. The most recent file in this cluster, the Department of the Army submission from 2026, is the most recent record in the entire PURSUE release as of this writing.
