2021·Military range, western U.S. (exact location undisclosed)
United States.Western U.S. · an infrared sensor records three distant dots
In 2021, an infrared video sensor at a military range in the western United States recorded three unidentified objects. On May 31, 2023, Sean Kirkpatrick, director of the Pentagon office for these phenomena (AARO), presented the case to a NASA study team and declared it closed: by matching the video against commercial flight data, AARO assessed that they were three airliners far from the sensor, whose radar tracks lined up with the objects and which at that distance looked like dots. The radar data, the date and the location have not been published, so no one outside the government can repeat the check.

"Western U.S. Objects" — full video presented to the NASA panel, May 31, 2023 (8:29)
An 8-minute 29-second infrared video that AARO showed NASA's study team on May 31, 2023, published the same day by the Department of Defense on DVIDS as a public-domain work. It has no narration, overlaid text or sound: AARO's assessment (three distant commercial aircraft whose radar tracks matched the objects) appears only in the DVIDS description. The case is not part of the 2026 PURSUE releases.

What happened
At some point in 2021 (the exact date was not published), an infrared video sensor recording from a military range in the western United States, whose exact location was not disclosed either, captured three unidentified objects within its field of view. When the case was actually resolved is not known: it became public on May 31, 2023, when the director of the All-domain Anomaly Resolution Office (AARO), Dr. Sean Kirkpatrick, presented it at an open meeting of NASA's Independent Study Team on Unidentified Anomalous Phenomena.
Unlike most of the cases Kirkpatrick showed in his 2023 public appearances, this one arrived with a complete resolution in the same presentation. Per the official description published alongside the video, AARO analyzed the full-motion video and cross-referenced it against the region's commercial air traffic data. The conclusion is worded as an AARO assessment, not as a certainty demonstrated in public: the objects were three separate commercial aircraft flying at a great distance from the sensor, and the radar tracks of those flights "aligned" with the three objects in the infrared video. At that distance the aircraft were not recognizable as such: they appeared only as small dots, with no discernible shape, wings or fuselage, exactly the kind of ambiguous image that, without that cross-check, would simply have been cataloged as "unidentified UAP."
The video was released in two versions, one of 8 minutes 29 seconds and a shortened one of 3 minutes 51 seconds that appears to be a trimmed cut of the same footage; both are public-domain works. Neither has narration, overlaid text or sound, so Kirkpatrick's explanation is not in the video: it lives only in the accompanying description on DVIDS, the platform through which the Department of Defense published it. The long video mostly shows gray sky and, later, cumulus clouds, with the sensor reticle at the center.
The three objects are visible from the start as three faint points, and around the four-minute mark they appear for about forty seconds as three short, nearly parallel streaks with the same tilt, spread across the frame, with no shape or detail at all. That arrangement, three points with the same orientation, like aircraft following the same airway, is consistent with the official explanation, though it does not prove it on its own.
Why it matters
Three dots with no recognizable shape, seen at a great distance and with no further context, cannot be told apart from a "generic anomalous object" of the kind that populates much of the UAP literature. What resolved them was not an analysis of their flight or their shape, neither of which was discernible, but overlaying their paths on an independent record: the actual air traffic in the area at that time.
The transparency of that resolution is limited: AARO did not publish the date, the location, the identified flights or the radar tracks, so today no one outside the government can repeat the cross-check. The resolution is verifiable in principle, but has not been independently verified.
Kirkpatrick repeatedly noted in his appearances that much of UAP reporting does not describe genuinely anomalous objects, but ordinary objects observed under conditions (distance, sensor resolution, lack of flight data) that prevent identification with the means available at the time of observation. AARO's assessment of this video fits that pattern: an official resolution backed by a radar cross-check and consistent with what the video itself shows.

"Western U.S. Objects" — shortened version of the same infrared video (3:51)
A shortened 3-minute 51-second version of the same infrared video, published on DVIDS on May 31, 2023; it appears to be a trimmed cut of the long video. It too has no narration, overlaid text or sound: Kirkpatrick's explanation is in the DVIDS description, identical for both versions.

NASA · Unidentified Anomalous Phenomena — Independent Study Team Report (Sep 2023)
Final 33-page report of the independent study team on UAP that NASA convened in 2022: sixteen scientists and experts chaired by astrophysicist David Spergel, who worked only with unclassified data and held public meetings, the first in May 2023, where the more than 800 cases gathered by AARO were discussed.

Published on September 14, 2023, it finds no evidence of an extraterrestrial origin but offers no conclusive explanations for the best-documented cases either, and attributes the problem to sparse, scattered, uncalibrated data. It recommends using NASA's satellites, reducing the stigma of reporting and applying machine learning. It is a methodological document, and its conclusion is conditioned on the poor quality of the available data.
