The United States has been officially investigating unidentified flying objects, on and off, since 1948 — and the paper trail of those investigations is the most solid thing in the entire subject. This collection gathers every AnomalyDesk file on an official program, panel, or report, from the first Air Force studies to today's All-Domain Anomaly Resolution Office. Read in sequence, they tell a single long story: not of a cover-up of alien craft, but of a government that has never been able to decide whether the phenomenon is a threat, a nuisance, or nothing — and has kept re-opening the file to find out.
The programs below fall into a rhythm that repeats. A wave of sightings creates political pressure; the Air Force or the Pentagon stands up a study; the study explains most cases as aircraft, balloons, and misperception, flags a residual few it can't, and is then wound down or debunked — until the next wave. Project Sign gave way to Grudge, Grudge to Blue Book, Blue Book was closed by the Condon Committee's verdict in 1969, and the subject went officially dormant for four decades. Then AATIP surfaced in 2017, the UAP Task Force formalized it in 2020, and AARO institutionalized it in 2022.
What changed in the modern era is not proof of anything exotic; it's the evidence base. Early programs ran on eyewitness reports. Today's run on military sensor data — radar, infrared, pilot instrumentation — which is harder to wave away and harder to interpret. AnomalyDesk tracks both the continuity and the break.
The Air Force's public UFO study (1952–1969): 12,618 cases, the 701 that stayed "unidentified," and the Condon verdict that shut it down.
The Advanced Aerospace Threat Identification Program — the Pentagon effort revealed by the 2017 New York Times report that reopened the subject and released the Navy sensor videos.
The Pentagon office's own 2024 review of every U.S. UAP program since 1945 — and its conclusion that it found no evidence of recovered off-world technology.
Every published file, in rough chronological order. Each links to the full case.
These are the best-documented files in the whole UFO subject, which makes discipline easy and important. A program's stated findings are reported as what the program concluded — not as ground truth and not as a presumed lie. Where a study genuinely left cases unexplained (Blue Book's 701, AARO's residual percentage), that's stated as unexplained, meaning insufficient data — not confirmation of anything. Where later advocacy has read a cover-up into a memo the document doesn't support (the Wilson-Davis notes), the gap between the paper and the claim is the file. The throughline of this collection is process, not proof.
