The 10 Most Anomalous Files

How this ranking works

The Anomalousness Index is a six-axis open rubric applied to every file in the PURSUE disclosure. Each file is scored on sensor quality, witness credibility, corroboration, kinematic anomaly, mundane-explanation availability, and official disposition. Weights sum to 1.00. The full rubric and weights are published as open JSON so any reader can audit or recompute every score in this list. See /methodology for the per-axis derivation.

The top eight files are tied at 72 - the highest score in the archive. They are the December 1965 Gemini 7 air-to-ground audio in which astronaut Frank Borman reports an unidentified object to NASA mission control, the Gordon Cooper interview excerpt, the two Apollo 16 scientific debriefings, the two Apollo 14 crew debriefings, and the two Apollo 17 crew medical debriefings. What lifts them to 72 is the witness-credibility axis: an astronaut on the official federal record is the rubric's highest witness tier. See our Borman Incident deep dive for the Gemini 7 walkthrough.

Positions 5 through 10 are tied at 70 - the FBI's authenticated orb and triangle sightings and digital recreations. Below the top 10, the densest single band in the archive is the 92 files tied at 66 - U.S. military mission infrared captures (the 27-file Release-01 AARO cluster, the Release-02 DOW-UAP-PR video series, and Release-04 additions), mostly logged unresolved with no formal review at AARO. They share the same evidentiary profile, which is what produces the tie. See our AARO Unresolved UAP deep dive for the geographic and sensor breakdown.

What this ranking is NOT: it is not a probability of extraterrestrial origin. That number is not honestly computable from the released metadata, and this site refuses to publish it. The score is evidentiary weight that an encounter remains structurally unexplained after conventional analysis - nothing more.
