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.

Tremonton Film: Conflicting Technical Assessments
This Project Blue Book file preserves Delbert C. Newhouse’s account and film submission from the 2 July 1952 Tremonton incident. Newhouse said the sky supplied no fixed reference for estimating distance, size, altitude, or speed. Navy analysts favored an unidentified light-source interpretation under disputed assumptions, while later reviews considered balloons, birds, insects, and mirage; one 1956 study remained inconclusive before an Air Force memo adopted a seabird explanation.
AAWSAP’s 2008 research objectives and requirements
DIA’s July 2008 AAWSAP objectives call for studies of breakthrough aerospace technologies and their implications for foreign threats through 2050. The four-page statement specifies research fields, expert qualifications, security requirements and a sequence of reports; it describes commissioned work, without establishing that the proposed technologies had been achieved.
AAWSAP contract award, schedules and data rights
This 59-page AAWSAP contract identifies BAASS, the September 2008 award, scheduled reports and government data rights. The released copy also includes a $21.95 million total and performance dates extending into December 2010, so it should be read with the later modifications rather than as an untouched record of the original award. Most pages contain standard procurement terms.
Metallic Glasses for Aerospace
This reference evaluates metallic glasses as possible aerospace structural materials. It highlights high strength and thermoplastic processing alongside low ductility, fatigue concerns, and the lack of lightweight glass-forming alloys.
Metallic Spintronics
This reference reviews metallic spintronics, including giant magnetoresistance, magnetic multilayers, spin-transfer torque, and memory concepts. It describes experiments and device challenges in a developing condensed-matter field rather than an extraordinary sensing or propulsion capability.
Ruppelt’s 1952 briefing: unresolved reports and better measurements
This official transcript preserves a March 1952 presentation attributed to Captain Edward J. Ruppelt on the Air Force handling of unidentified-object reports. It records proposed data-collection methods, reported cases and alternatives, and repeated cautions that the available evidence did not establish the nature or origin of the reported phenomena.
DOW-UAP-PR159, Historical Film of Reported UFOs, Utah, 1952
This digitized 16 mm print shows low-detail bright marks against the sky from the 1952 Tremonton film. The official description says missing fixed reference points prevented a conclusive identification. At 00:55 the release changes to unrelated sewing-equipment footage; the record does not explain when or how the material was combined, and the reviewed imagery does not identify the airborne marks.
DOW-UAP-PR160, Presentation by Captain Edward J. Ruppelt, 1952
This 65-minute DVIDS recording preserves a March 1952 presentation associated with Captain Edward J. Ruppelt and the Air Force’s reorganized UFO investigation. Its official D154 companion transcript is indexed here in 19 sequential page-level spans with approximate audio locators. The presentation discusses unresolved reports and proposed data collection while stating that the Air Force had no conclusive evidence about the phenomena’s nature or origin.
LLE-UAP-PR001, Unresolved UAP Report, Colorado, 2023
A Colorado law-enforcement officer submitted this 79-second cellular-camera video from October 2023 and described a silent light flashing red, blue, and green. The official timeline says the camera pans and changes magnification while keeping an apparent light source near center; the lower frame was blurred for privacy. AARO warns that autofocus and image processing can distort distant subjects, and the reviewed footage does not identify the light.
LLE-UAP-PR002, Unresolved UAP Report, Colorado, October 2023
A Colorado law-enforcement officer submitted this 15-minute cellular-camera video from October 2023 and described a silent light flashing red, blue, and green. The official timeline says the camera keeps an apparent light source generally centered for the full clip, while the lower frame is blurred for privacy. AARO warns that phone autofocus and image processing can alter apparent shape and motion; the footage does not establish the light’s identity.
Tremonton Photo File: Limits and Alternatives
This short Project Blue Book photo file records the 2 July 1952 Tremonton observation associated with CPO Delbert C. Newhouse. It says the photographed objects were too small and lacked reference points for estimating size, distance, or speed, and it lists pillow balloons or birds as possible explanations rather than a settled identification.
Delbert Newhouse’s Navy career and photographic service
Delbert Newhouse’s Navy personnel file documents a career in photography through assignments, qualifications, evaluations and retirement orders. It includes both favorable and critical performance appraisals and material dated later than the catalogue’s 1957 label. These records establish professional background; they do not independently identify the objects in his Tremonton film.
Air Force UFO correspondence, film inquiries and physical evidence
This Air Force correspondence file follows film-analysis requests, witness statements, interservice coordination and physical-evidence inquiries during 1952. It includes Newhouse’s explicit limits on estimating the Tremonton objects, the effort to recover a misplaced Mariana film copy, and FBI examination of a reportedly burned cap. Questions and proposed explanations remain distinct from established identifications.
DOW-UAP-D106, Mission Report, Iraq, 2022
This May 2022 mission report records an FMV observation that the reporting unit described as UAP activity during an Operation Inherent Resolve mission. It reports estimated speed and size while stating altitude could not be determined, so the record does not identify an object or establish its performance.
DOW-UAP-D107, Mission Report, Middle East, 2025
This October 2025 mission report records a UAP incident during an Operation Inherent Resolve mission. It preserves the observer’s description and reported speed, but the form leaves velocity and trajectory fields blank or estimated and does not establish identity or a measured performance.
DOW-UAP-D108, Mission Report, Middle East, 2025
This July 2025 mission report records a UAP incident during an Operation Inherent Resolve mission. The form preserves descriptions and an estimated velocity while also recording unknown control and propulsion, no material recovery, and no asserted advanced capabilities.
