A release chronology built for research
The official PURSUE portal publishes files in numbered tranches. Probed preserves the release identity and publication date, then separates those values from the date of the underlying incident or document. That distinction prevents a newly published historical record from being mistaken for a newly reported event.
Use the tracker to move from a tranche to its individual files, then follow the official source link. Stable release pages are the canonical research entry points; temporary query filters remain useful product state but are not separate search destinations.
Compare agencies without flattening provenance
Agency labels describe the organization attached to a released record. They do not always identify every office that collected, reviewed, transferred, or published it. Probed retains the supplied agency value and release context, while the National Archives collection supplies a separate archival view organized by transferring agency and record group.
Cross-agency comparisons should use file identifiers, dates, locations, and source text—not titles alone. The same incident may produce records in more than one system, and a historical file can be republished in a later transparency release.
Dataset methodology and fields
The downloadable Probed CSV contains only canonical UFO Files assets that pass the public quality gate. Each row records the Probed URL, official title, file type, agency, release identifier, release date, incident date or date label when available, and official source URL. It is a navigation dataset, not a claim that every field in a government record has been independently verified.
The export is regenerated from the same normalized tracker data used by this page. Blank values mean the source data did not provide a stable value. Probed does not infer a precise incident date from an imprecise label in the CSV. Field names are documented in the header and the export includes a generated-at timestamp for reproducibility.

DOW-UAP-D098, Film Analysis of Unidentified Objects, 1953
A 1953 Naval Photographic Interpretation Center progress report analyzes motion-picture footage recorded in Utah and Montana in 1952. It documents photogrammetric and densitometric methods, describes blue-white disk-like images, and reports calculated motion while retaining assumptions and limits in the analysis.
FBI-UAP-D025, Rendering, “Airborne Triangle,” 2002
The rendering depicts a large, unlit black triangular silhouette occluding a star field. This is an FBI artistic reconstruction rather than a photograph of the reported event; this image is based upon a first-hand description provided by a former military service member, as described in FBI-UAP-D024.
FBI-UAP-D027, Rendering, “Dark Translucent Triangle,” 2023
A five-frame digital reconstruction depicts a dark, low-contrast triangular aerial object crossing a residential night sky. The sequence shows the object at changing positions and orientations but does not establish scale, distance, speed, or physical composition.
FBI-UAP-D029, Rendering, “Dark Triangle with Lights,” 2011
The rendering depicts a dark triangular form with three diffuse white corner lights above a residential night scene. This is an FBI artistic reconstruction rather than a photograph of the reported event; this image is based upon a first-hand description provided by two former U.S. military service members, as described in FBI-UAP-D028.
FBI-UAP-D031, Rendering, “Large Triangle with Red Lights,” 2023
The rendering depicts a dark triangular form with three red corner lights above a lit parking area. This is an FBI artistic reconstruction rather than a photograph of the reported event; this image is based upon a first-hand description provided by a U.S. Person, as described in FBI-UAP-D030.
FBI-UAP-D038, Rendering 1, “Multiple Red Lights,” 2026
A single digital rendering depicts two small red lights above a desert mountain ridge at dusk, viewed from beside a parked vehicle. The image is an illustrative reconstruction and does not independently establish the lights’ distance, altitude, size, or source.
FBI-UAP-D039, Rendering 2, “Multiple Red Lights,” 2026
Three digital renderings present a bright circular light through a binocular or night-optics field, with concentric halo rings and a mountainous horizon. The repeated frames illustrate an optical appearance rather than independently measuring the light’s range, size, or motion.
FBI-UAP-D041, Rendering 1, “Multiple Red Lights,” 2026
A six-frame digital sequence depicts red lights appearing in increasing numbers above a desert mountain ridge while an observer stands beside a vehicle. The rendering illustrates the reported arrangement and progression but cannot establish physical distance, altitude, or object identity.
FBI-UAP-D042, Rendering 2, “Multiple Red Lights,” 2026
A single digital rendering shows a narrow luminous streak rising above a mountainous horizon within a binocular or night-optics field. It is an illustrative reconstruction and does not independently determine the streak’s source, trajectory, distance, or duration.
CIA-UAP-D022, Unidentified Flying Object Reported near Puerto Rico, 1965
A 1965 intelligence memorandum reviews radar photography and pilot observations connected to unidentified-aircraft reports near Puerto Rico in November 1964. It rejects a high-altitude ultra-high-speed interpretation for one track while assessing the November 19 object as probably a high-performance delta-wing fighter.
CIA-UAP-D023, Briefing Notes for Mr. Walter Elder
Briefing notes summarize radar and pilot observations near Puerto Rico during November 1964. They describe a radar contact involving USS Gyatt, a Crusader pilot’s view of a delta-shaped object, and reported performance estimates while noting that naval intelligence had no further information.
DOS-UAP-D001, Diplomatic Cable, Brazil, November 14, 1963
A November 14, 1963 State Department cable relays an unverified telephone report from Bahia concerning a large metal object, an alleged dead crewman, and an impact crater. The cable requests cooperation from air and science attaches and records onward passage to Defense and NASA.
DOS-UAP-D002, Diplomatic Cable, Brazil, November 20, 1963
A November 20, 1963 diplomatic dispatch reports that local inquiries found no support for the alleged object near Conde, Bahia. It cites a consul’s telegram and two newspaper accounts, including a categorical denial by the Ministry of Aeronautics, and characterizes the original story as fabricated.
DOW-UAP-D099, Intelligence Review of “Ghost Rocket” Incidents, 1947
A January 1947 War Department intelligence review assesses the 1946 Scandinavian “ghost rocket” reports. It contrasts highly variable witness accounts with official investigations, notes the absence of recovered direct evidence, and concludes that only a small number may have involved low-flying V-1-type missiles while many high-altitude reports were likely meteors or fireworks.
DOW-UAP-D100, Air Materiel Command Report on Unidentified Flying Objects
This 245-page historical file assembles 1947-1948 Air Force correspondence, sighting reports, investigative requests, policy memoranda, and analytical papers associated with flying-disc inquiries and Project SIGN. It documents how Air Materiel Command gathered reports, coordinated intelligence collection, evaluated possible explanations, and considered the problem unresolved despite identifying some reports as balloons or astronomical objects.
DOW-UAP-D101, Unresolved UAP, Gulf of Oman, 2021
A declassified intelligence information report describes approximately 25 infrared observations during an AC-130 live-fire training mission over the Gulf of Oman on September 8, 2021. It records cold-orb appearances, formation and maneuver observations, crew speed estimates, missing propulsion indicators, and the failure of the aircraft recorder to preserve all footage.
