The 2026 Western US Black Triangle: What the AARO and FBI Files Say

What Is the 2026 Pentagon Black Triangle Sighting?

The 2026 Pentagon black triangle is a sighting by federal law-enforcement agents at an unnamed site in the western United States, recorded in two documents the Department of War published on 23 October 2026 in PURSUE Release 7: an AARO memorandum for record, DOW-UAP-D176, and an FBI FD-302, FBI-UAP-D043. The Pentagon pairs them as accounts of the same event.

AARO, the Pentagon's All-domain Anomaly Resolution Office, debriefed two agents at a "primary observation post". It added an account from a third official at a second post, who spotted the object and radioed them. The FBI form reproduces a written statement by one special agent, co-signed by the other. Neither file names the agents, their agency, the site or the state. Both black out the date; "June, 2026" comes from the Pentagon's release notes.

The two accounts agree on the shape and disagree on almost everything you could time. Our round-up of the Pentagon's seventh UFO file release covers the rest of the batch, and our guide to the US PURSUE releases explains how the releases work.

What Did the Federal Agents See? AARO's Black Triangle Memo

In AARO's version, the agents watched a small, matte-black triangle climb straight up over a ridge for about ten seconds, hover for about twenty, then bank and dive into a canyon in two to three seconds, in silence. The memo opens with a caveat that covers every figure in it:

It was 2023L (local time), in "late-dusk illumination", with the sunset glow behind the western ridges. The agents' main sensors faced east. The official at the second post, "scanning westward with long-range thermal equipment", called out the contact, and the pair crossed the peak with binoculars and a handheld thermal monocular. AARO describes "a matte black triangular shape of extremely low aspect ratio", with an estimated 13–15 ft wingspan, 6–9 ft long and 1–2 ft thick. It rose to 200–300 ft above the ridge, 1.4 to 3.2 miles west, and hovered without drifting. Then:

Through the monocular it showed a "spatially uniform thermal signature" with no hot spots or exhaust, and there was "absolute acoustic silence". A ground survey of the canyon the next morning "located no wreckage, ground scarring, or vegetation damage". The memo draws no conclusion.

What Does the FBI Black Triangle File Say?

The FBI file is the agents' own written account, and it describes a shorter event: a dark triangle that rose over a ridge, climbed about 200 ft and shot off towards them, all in about three seconds.

At "approximately 1923 hours" a colleague at "Observation Post 6" called out "a thermally elevated aerial object" to the west. The two agents ran to the west side of their post and "almost immediately observed a substantial, nonreflective, dark black triangular object most resembling a delta wing drone", with a wingspan of nine to 15 ft. Through a handheld thermal device it "appeared hotter than ambient temperature", with an even signature and no exhaust.

It rose over a ridge about 3.2 miles west, climbed about 200 ft, "then transitioned from vertical to horizontal flight at a very significant velocity, approaching our position, then descending southeast". They lost it at about 1.5 miles. "The total duration of the sighting was approximately three seconds." Neither heard a sound. Like every FD-302, the form "contains neither recommendations nor conclusions of the FBI".

Where Do the AARO and FBI Triangle Accounts Agree and Differ?

The AARO and FBI accounts agree on the triangle's shape, depth, thickness, silence and even heat, and differ on the time, the wingspan, the hover and how long it was in view. Neither document refers to the other or explains the gaps.

The biggest gap is time in view. The FBI's three seconds includes the climb ("We both observed the object ascend vertically"), and only AARO has the hover. The clocks are exactly an hour apart, and neither file says why. AARO's "SOURCE 3" and the FBI's caller at Observation Post 6 look like the same person, though that is our inference.

Did the Black Triangle Really Fly at 1,800 mph?

No. The 1,800 mph quoted in news reports of the black triangle appears in neither file, and neither file gives a speed figure at all. It is what you get by dividing 1.5 miles by three seconds.

Both numbers are in the FBI statement, but they don't describe a journey. The 1.5 miles is how far away the object was when the agents lost it, and the three seconds covers the whole sighting, climb included. On speed, AARO records only that the observers described it "as fast as a fighter jet" and that "No instrumented speed measurement was obtained". The FBI says "a very significant velocity". Reports that thermal cameras couldn't detect the object get both files backwards: both record an even heat signature.

Are the FBI Black Triangle Images Real Photographs?

No. The nine images on pages 3 to 11 of the FBI triangle file are composites: the same landscape photograph each time, with a black shape added at a different position. They are not photographs of the object.

The pages have no captions or labels, and neither document says who made them or when the base photograph was taken. In order, they show an edge-on sliver against the far hillside, a flat triangle above the ridge, a steeper triangle as it banks, then a shrinking shape dropping into the valley: the memo's climb, bank and "terrain-hugging descent into a canyon drainage".

The base photograph is a well-lit landscape with snow on the distant ranges, which doesn't look like late dusk in June, so it may be a reference shot taken at another time. That is our reading of the picture, not something the file says. We haven't tried to identify the place.

Was There a Second Black Triangle Sighting the Next Evening?

The Pentagon's release notes say the AARO memo records a second sighting the following evening, but the released memo doesn't contain one. An FBI statement released in August, FBI-UAP-D033, fits the description, though no document links the two.

The notes promise "a secondary observation on the following evening" and "associated analytic support material". The three released pages cover one evening and the next morning's search, and nothing else. D033, from the Pentagon's fifth release, carries the same "Unidentified Aerial Object Observation Report" heading as the triangle file and the same phrase, "thermally elevated aerial object". At about 2100 hours, from "the same general observation area referenced in my prior statement", a special agent wrote:

That object was "approximately two ridge lines farther west", flying south, and about half the size of an Army Black Hawk the agent filmed for scale. The June triangle rose over a western ridge and went off to the southeast, so D033 is consistent with being the "following evening". That is our inference: nothing on paper connects them, and D033 gives no date beyond 2026. Our report on the FBI's 2026 red lights over the western US covers D033 and the other Release 5 statements.

How Does the 2026 Triangle Compare With Other Black Triangle UFO Sightings?

The 2026 object is a small, fast, silent, unlit delta, not another giant black triangle. Its estimated 9–15 ft span is drone-sized, against the 200 to 500 feet estimated for the largest triangles in the files released in August.

Those FBI interviews are on our black triangle UFO files page: the Bagram triangle of 2002 at 500 feet, a 200-foot triangle with white corner lights in 2011, and a Colorado Springs triangle in October 2023 with red corner lights, also covered on our Colorado orbs page. They share the silhouette and mostly the silence. The 2026 object had no lights and was 1–2 ft thick, and AARO notes no "cloaking, optical shifting or distortion", unlike the haze both Colorado Springs witnesses described.

The closer match is the October 2023 "orbs launching orbs" Western US event. Those witnesses were also federal law-enforcement agents, watching at dusk among ridges, and AARO's own 2023 memo places them near "a sensitive national security site in the western United States". For 2026, that phrase appears only in the release notes. One 2023 agent described a dark object that "seemed to be using the terrain to stay hidden". But 2023 was mostly lights, over two nights, seen by six agents in roving teams, and the phrase "observation post" never appears in its files. Nothing released puts the two at the same site.

Why Does AARO Say the Triangle Warrants Further Investigation?

AARO's call for further investigation comes from the Pentagon's release notes, not the memo. The notes say the triangle's reported shape and movement closely match other incidents in the western US, without saying which.

The memo itself contains no assessment, comparison or recommendation. Its nearest thing to a judgement is the italic caveat quoted above, at the top of page 1, which the release notes repeat in their own words. So the caution is AARO's own, written into the memo; the call for more work is the Pentagon's summary of AARO's view.

What Could the 2026 Black Triangle Have Been?

Neither file says what the 2026 black triangle was. The agents' first description was "a delta wing drone", while AARO records their view that a small drone that close would have been heard.

The FBI statement's "delta wing drone" and "unmanned aerial system" describe what the agents saw, not an FBI finding. AARO calls it an "unidentified craft" throughout. Its collector's note says the agents have "extensive operational experience" with unmanned aerial systems, and that on that hilltop "even a conventional Group 1 drone, high-torque quadcopter motor, or rotary-wing aircraft operating at a distance of 1.4 miles would have been clearly audible". Group 1 is the smallest class of military drone.

Two details limit the numbers. The hearing test applies to the near end of a 1.4 to 3.2 mile range. And the agents judged size against "the trees along the ridge line behind it", which is only accurate if the object was at the ridge: anything nearer would be smaller than it looked.

An unlit shape above a ridge isn't a planet, star or satellite, but plenty of dusk sightings are.

Binoculars come first, as they did for these agents, and our binocular astronomy guide shows how to hold them steady.

What the agents reached for first

Kit we've reviewed in full

When the call came, one agent ran across the hilltop with binoculars and a handheld thermal monocular, and the binoculars were passed to the other. We don't sell thermal kit, but binoculars are the same first step for anyone trying to put a name to something low over a ridge at dusk.
