The physical record of UAP flight characteristics: instantaneous acceleration, hypersonic velocity without sonic boom, trans-medium transition between atmosphere and water, the absence of typical aerodynamic wake. Drawn from named-witness testimony, sensor data, and the peer-reviewed physics literature.
The 2021 ODNI Preliminary Assessment described the observed UAP flight characteristics in five categories: 'remaining stationary in winds aloft, moving against the wind, manoeuvring abruptly, moving at considerable speed, and not showing identifiable means of propulsion.' Subsequent AARO Historical Record reporting and congressional testimony have repeated and extended that taxonomy.
The peer-reviewed treatment begins with Knuth et al. (2019, 'Estimating Flight Characteristics of Anomalous Unidentified Aerial Vehicles', published in Entropy), which derives quantitative bounds on the implied accelerations and propulsion power for a small set of well-documented cases. The 2024 AIAA review (Powell et al., 'Reported Shape, Size, Kinematics ... of UAP from Select Reports, 1947–2016') extends the dataset to thousands of cases and provides the statistical baseline.
The Loeb & Kirkpatrick paper. The 2023 Harvard CfA preprint co-authored by Galileo Project founder Avi Loeb and then-AARO director Sean Kirkpatrick ('Physical Constraints on Unidentified Aerial Phenomena') is the single most-cited treatment of the question: what envelope can UAP behaviour occupy before requiring physics outside the current standard model? The paper is on the Research library page.
Why this matters. The flight-characteristics record is the part of UAP that is least dependent on cultural interpretation. Either the sensor and witness reports are consistent with conventional aerospace technology, or they aren't. The peer-reviewed literature now treats that question as empirically tractable, not metaphysical.

The Trump administration launches PURSUE — the Presidential Unsealing and Reporting System for UAP Encounters — and the Department of War publishes 160 declassified UAP-related files in the first tranche: 117 PDFs, 29 sensor videos, and 14 photographs spanning 1944 to 2026. Secretary of War Pete Hegseth says the goal is 'maximum transparency.'
The most recently dated video in PURSUE Release 01 — DOW-UAP-PR49, captured in 2026 by a U.S. Department of the Army sensor — runs 1 minute 49 seconds and shows infrared tracking of an unresolved aerial object.
A 2-minute-57-second AARO video from a U.S. military sensor records an unidentified object over Greece performing multiple sharp 90-degree turns at speed — flight characteristics that exceed publicly disclosed performance of known aircraft. Released as DOW-UAP-PR34 in PURSUE Release 01.
The House Intelligence Subcommittee on Counterterrorism, Counterintelligence, and Counterproliferation holds the first open congressional hearing on UAP in fifty-three years. Under Secretary of Defense for Intelligence Ronald Moultrie and Deputy Director of Naval Intelligence Scott Bray testify.
A U.S. Navy Range Fouler debrief from May 14, 2020 documents a 'solid white object' performing erratic movements above the water of the Persian Gulf — a close-proximity encounter with active U.S. military training. Released as DOW-UAP-D38 with companion video DOW-UAP-PR36.
The Pentagon publicly releases three U.S. Navy gun-camera videos — 'FLIR1' (2004), 'GIMBAL' (2015), and 'GO FAST' (2015) — and confirms that the objects depicted remain unidentified. The release marks the first formal U.S. government acknowledgment of authentic military UAP imagery.
Helene Cooper, Ralph Blumenthal, and Leslie Kean publish a front-page New York Times investigation revealing the existence of the Department of Defense's Advanced Aerospace Threat Identification Program. The story includes a release of the 'FLIR1' video and on-the-record statements from former AATIP director Luis Elizondo.
F/A-18F crews assigned to Strike Fighter Squadron 11, operating from Naval Air Station Oceana, report routine encounters with UAP off the U.S. East Coast. Two of the three Pentagon-released videos — 'GIMBAL' and 'GO FAST' — are recorded during this period.
The oldest sensor video in PURSUE Release 01 — a 1-minute-46-second AARO clip from 2013 — shows what military observers described as an 'eight-pointed star formation' of objects over a Middle Eastern theater of operations.
Aircrews from the USS Nimitz Carrier Strike Group report repeated radar contacts and a daylight visual encounter with a small, white, smooth, Tic Tac–shaped object during a training exercise in the Pacific. One of three Pentagon videos later released by the Department of Defense (FLIR1) documents a portion of the event.

U.S. material is the single largest body in the public UAP record, but it isn't the only one. France's GEIPAN has run a transparent case database since 1977; the UK MoD released ~60,000 pages between 2008 and 2017; Japan's evolving track is the program currently moving fastest in 2026. Every state-run UAP-investigation body with a public archive — fifteen countries to date — is catalogued in one place.
