Section · What matters

The 20 items that actually matter.

Across the four PURSUE releases and the deeper historical record. Every entry pairs the claim the primary document actually supports with the claim it is often stretched to support. That second column is the whole point of this page.

The ranking is an editorial claim. Disagreement is fine. The “what it does not establish” column is not editorial. It is a discipline.

01Unresolved·R01
Nimitz Tic Tac, USS Princeton radar and F-18 encounter
The strongest publicly cited multi-sensor modern UAP incident. Included in R01 with formal DoW provenance.
What it says
Naval radar operators on USS Princeton tracked anomalous objects for days in November 2004; two F/A-18s vectored to intercept made visual and ATFLIR contact with a small oblong object exhibiting flight behavior the aircrews could not account for.
What it does not establish
Non-human origin. Advanced propulsion. Extraterrestrial technology. The record establishes that trained aircrews observed something they could not identify with multi-sensor corroboration. The next step in an evidence chain (raw radar tapes, complete ATFLIR telemetry, follow-on adjudication) has still not been released.
02Contested·R01
Gimbal, ATFLIR infrared video
The most analyzed sensor-derived UAP video in circulation. Central to the modern debate.
What it says
A US Navy F/A-18 ATFLIR pod recorded an infrared signature over the Atlantic in 2015 that appears to rotate against a background of clouds while the aircraft maneuvered.
What it does not establish
Genuinely anomalous flight behavior. The prevailing technical explanation (a gimbal-lock artifact from the ATFLIR mount as the aircraft banks) accounts for the apparent rotation. That explanation is contested by other analysts. The video alone is insufficient to settle the debate either way.
03Explained·R01
GoFast, ATFLIR infrared video
Alongside Gimbal the video most often shown to imply anomalous speed.
What it says
A US Navy F/A-18 ATFLIR pod recorded a small infrared object skimming above the Atlantic Ocean in January 2015. The pilots audibly react to what they perceive as high speed.
What it does not establish
That the object is moving fast. Range-parallax analysis using the ATFLIR's own displayed slant range indicates the object is close to the surface and drifting with the wind at roughly balloon speed. Prevailing explanation: mundane object (balloon or debris) misperceived as fast due to parallax against the ocean.
04Explained·R01
USS Omaha pyramid drone incidents
The most cited "pyramid UFO" imagery. Widely misinterpreted as anomalous.
What it says
Deck-shot night-vision video from USS Omaha in July 2019 shows several triangular light shapes off the ship's superstructure.
What it does not establish
That the objects are pyramid-shaped. The triangular appearance is a known imaging artifact of triangular lens apertures on night-vision equipment when recording out-of-focus point light sources. Prevailing explanation: bokeh from the camera aperture, actual sources most likely quadcopter drones. DoD Chief Public Affairs confirmed this artifact publicly.
05Administrative·R01
AARO FY2025 Annual Report to Congress
The single most important primary document for understanding what the US government thinks it can and cannot say about UAP.
What it says
AARO adjudicated hundreds of cases through FY2025. The overwhelming majority resolve to conventional aerial objects (balloons, drones, aircraft, birds, atmospheric optics). A small residual set remains formally unresolved due to insufficient data.
What it does not establish
That the unresolved cases are extraterrestrial or non-human. AARO's own framing: unresolved means the sensor data or witness accounts were insufficient to attribute, not that attribution to something exotic is warranted.
06Contested·Pre-PURSUE
Rendlesham Forest incident, USAF Bentwaters
The most cited Cold War military UAP encounter with named witnesses at senior rank. Not in PURSUE, but the historical anchor for the modern military-witness genre.
What it says
Multiple USAF personnel at RAF Bentwaters, including Lt Col Charles Halt, reported unexplained aerial phenomena over three nights in late December 1980. Halt's memo to the UK MoD is the primary document.
What it does not establish
Craft origin. Independent physical evidence. Prevailing explanations range from a fireball plus the Orfordness lighthouse (Ian Ridpath) to a genuinely anomalous event. Consensus has never emerged; the case is genuinely contested rather than settled.
07Administrative·R03
FBI Flying Disc file series, 62-HQ-83894
The core FBI UFO records now under PURSUE provenance. Historically foundational.
What it says
A 16-part FBI investigative file, opened 1947, documenting the Bureau's interviewing of witnesses and coordination with the Army Air Forces during the initial flying disc wave.
What it does not establish
That the FBI concluded anything about origin. The file documents investigation, not adjudication. Most disc reports were later attributed by AAF to weather balloons, kites, or misidentification.
08Unresolved·Pre-PURSUE
Tehran F-4 intercept, September 1976
The DIA Information Report is the most cited pre-PURSUE government document acknowledging systems anomalies during a UAP encounter.
What it says
Two Imperial Iranian Air Force F-4 Phantoms scrambled on a bright object over Tehran. Both experienced instrument and radio issues during the encounter, per the pilots and the DIA report.
What it does not establish
The cause of the systems anomalies. Possible explanations range from genuine EMI from an unknown source to more mundane instrument issues in aging airframes. The DIA report itself is descriptive, not adjudicative.
09Unresolved·R01
Extended-duration Army IR video, DOW-UAP-PR49
Longest sensor-video record in R01 by duration. Analyst-friendly.
What it says
Roughly 109 seconds of continuous infrared footage submitted by the Department of the Army from an encounter in early 2026, location undisclosed by the release.
What it does not establish
Object identity, distance, or altitude. Without accompanying sensor telemetry (range, aircraft attitude, sensor-mount state), the video is a compelling data trace but not an evidence-establishing document.
10Explained·Pre-PURSUE
Kenneth Arnold sighting, Mount Rainier
The origin of the modern flying-disc conversation. Historically load-bearing.
What it says
Civilian pilot Kenneth Arnold reported nine crescent-shaped objects flying in formation near Mount Rainier on June 24, 1947, at estimated high speed.
What it does not establish
The objects were saucers. Arnold described their motion as "like a saucer if you skipped it across the water," a phrase press misconstrued as a shape claim. Prevailing explanations range from optical misidentification of aircraft or terrain-reflection to mirage. The term "flying saucer" is a linguistic artifact, not a shape observation.
11Administrative·Pre-PURSUE
CIA Robertson Panel report, January 1953
The formative government-side judgment on UAP as a national security issue. Continues to shape policy language.
What it says
A CIA-convened panel of scientists reviewed UFO material and concluded that no evidence pointed to a foreign or extraterrestrial threat; the panel recommended public debunking to reduce reporting-channel overload.
What it does not establish
That there is nothing to investigate. The panel's charter was national-security threat assessment, not phenomenology. It did not evaluate every report on its own merits and it is often over-cited by both skeptics and disclosure advocates for claims the report does not make.
12Contested·Pre-PURSUE
Trans-en-Provence physical trace case
The most cited government-analyzed physical-trace case. France's GEIPAN produced a formal report.
What it says
In January 1981, a farmer near Trans-en-Provence reported observing a metallic object briefly land and depart. GEIPAN gendarmerie investigation the following day documented soil disturbances and vegetation changes at the reported landing site.
What it does not establish
The identity of the object. GEIPAN's Class D (unexplained) classification means the case did not resolve to a known cause on the available evidence, not that the phenomenon is exotic.
13Administrative·R01
IC-side cover package accompanying R01
The framing document for the PURSUE unsealing process itself.
What it says
The Office of the Director of National Intelligence and the AARO transmitted a joint framing statement accompanying R01, laying out the adjudicative categories and the criteria for future tranches.
What it does not establish
That every subsequent tranche will follow the same rigor. The framing is a policy commitment, not a technical claim. Compliance across agencies has varied.
14Explained·Pre-PURSUE
STS-48 space shuttle downlink footage, 1991
The most cited NASA-affiliated "UFO on video" case. Widely reposted.
What it says
Downlink video from the Space Shuttle Discovery during STS-48 shows small illuminated objects moving relative to the Earth's limb, with one changing direction after a light flash.
What it does not establish
That the objects are craft. Prevailing explanation: ice particles vented from the shuttle, moved by an RCS thruster firing. NASA and independent analysts have converged on this account. The case remains widely presented as anomalous in popular UFO media, which is misleading.
15Unresolved·Pre-PURSUE
Coyne Army helicopter encounter, Mansfield Ohio
Multi-witness military encounter with reported physical effects (altitude gain without pilot input). Well-documented.
What it says
Captain Lawrence Coyne and crew reported a near-collision with an unknown object during a night flight in October 1973, followed by an unexplained 500-foot altitude gain.
What it does not establish
The nature of the object. Prevailing skeptical accounting (misidentified meteor or aircraft plus altimeter misread) is contested by the crew's own testimony. Genuinely unresolved on the evidence available.
16Explained·Pre-PURSUE
Guy Hottel memo, FBI, 1950
The most viewed document in the FBI Vault. Historically over-cited as a crash-retrieval confirmation.
What it says
A 1950 memo from FBI special agent Guy Hottel relaying a tip from an unnamed informant about "three flying saucers" recovered in New Mexico with occupants.
What it does not establish
That the FBI confirmed anything. The memo is a routine transmission of a raw tip. The FBI made no investigation, no confirmation, and the informant was never identified. The Bureau's own site describes the document as a tip that was never verified.
17Unresolved·R03
FBI Photo B7, western US 2025
One of the newest images in the corpus with a clear FBI provenance.
What it says
A single photograph from an FBI file on a 2025 sighting in the western US, entered into the FBI Vault and folded into PURSUE R03.
What it does not establish
That the image documents an anomalous object. Single-frame photographs without accompanying metadata, chain-of-custody detail, or sensor context are among the lowest-evidentiary media in the corpus.
18Contested·Pre-PURSUE
Lonnie Zamora, Socorro NM, 1964
The most cited single-officer landing-site case. Formally listed as unknown in Project Blue Book's final classification.
What it says
Sgt. Lonnie Zamora of the Socorro Police Department reported observing an egg-shaped object on the ground with two small figures nearby, then departing at speed, with physical trace evidence at the site.
What it does not establish
Craft origin. Recent revisionist accounts (student-prank hypothesis by NM Tech students) exist but are also contested. The case is genuinely unresolved rather than clearly explained or clearly anomalous.
19Administrative·Pre-PURSUE
Rep. Burlison UAP NDAA amendment, 2026
The most cited legislative vehicle in the 2026 disclosure conversation.
What it says
An amendment to the FY2027 NDAA, adopted by the House on July 23, 2026, that would establish a UAP Records Collection at the National Archives, an independent UAP Records Review Board, and disclosure duties on Department of War contractors. Modeled on the JFK Assassination Records Collection Act of 1992.
What it does not establish
That the amendment will survive Senate consideration and conference in its adopted form. The amendment is a policy vehicle, not a factual claim about UAP.
20Explained·Pre-PURSUE
Roswell 1947, AAF release and revisions
The most cited UFO case of all time. Load-bearing in popular UFO culture.
What it says
The Army Air Forces announced recovery of a "flying disc" near Roswell NM in July 1947, then retracted the statement within 24 hours describing the debris as a weather balloon. The 1994 Air Force report attributed the debris to Project Mogul, a classified acoustic-detection balloon program.
What it does not establish
A cover-up of non-human material. The prevailing historical account (Mogul balloon) is well-documented and accepted by most historians of the case. Later crash-retrieval claims are downstream of Stanton Friedman's 1978 interview of Jesse Marcel Sr., not of contemporaneous evidence.
