Two federal agents on a hilltop in the western United States watched a small black triangle rise over a ridge at dusk and drop into a canyon. The Pentagon published two official write-ups of that sighting on 23 October 2026: an AARO memorandum for record, DOW-UAP-D176, and an FBI FD-302, FBI-UAP-D043. They describe the same evening, and they don't agree.
We've set the two files side by side on our 2026 Western US black triangle page, with the full comparison table. This post is the short version. It covers where the two files part company, and what got lost between the documents and the headlines.
What Is the 2026 Black Triangle UFO?
The 2026 black triangle UFO is a sighting by two federal law-enforcement agents of a small, silent, matte-black triangle at an unnamed site in the western US. It comes from two documents released together in PURSUE Release 7: AARO's record of a debrief, and a statement the agents wrote themselves.
AARO, the Pentagon's All-domain Anomaly Resolution Office, debriefed the two agents and added a third official at a second observation post, who spotted the object first and radioed them. That is why some reports say three agents saw it: two watched it, and the third called it in. Its three-page memo opens with a warning that covers every number in it:
"This report reflects the reporter's interpretation at the time of the event."
AARO memo DOW-UAP-D176, p.1
The FBI file is shorter. It's a standard FD-302 that reproduces, word for word, a written statement by one special agent, co-signed by the other. Like every FD-302, it "contains neither recommendations nor conclusions of the FBI".
Neither document names the agents, their agency, the site or the state, and both black out the date. "June", "sensitive national security site" and "over two days" come from the Pentagon's release notes, not from either file. Our round-up of the Pentagon's seventh UFO file release covers the other 26 documents in the batch.
AARO vs FBI: Where the Black Triangle Accounts Differ
The AARO and FBI accounts agree on what the triangle looked like and disagree on almost everything you could put a clock or a tape measure to.
Both describe a nonreflective black triangle 6 to 9 feet deep and 1 to 2 feet thick, rising over a ridge to roughly 200 feet above it, silent throughout, with an even heat signature and no exhaust. After that:
| Detail | AARO memo (D176) | FBI statement (D043) |
|---|---|---|
| Time | 2023L (local) | "approximately 1923 hours" |
| Wingspan | 13 to 15 feet | 9 to 15 feet |
| Hover | about 20 seconds, "stable hover" | not mentioned |
| Time in view | about 10 + 20 + 2 to 3 seconds | "approximately three seconds" |
| What they called it | "unidentified craft" | "most resembling a delta wing drone" |
| Next-morning search | nothing found | not mentioned |
| Pictures | none | nine composite images |
The clocks are exactly an hour apart, and neither file says why. We haven't guessed. AARO's third witness at the "secondary observation post" and the FBI statement's caller at "Observation Post 6" look like the same person, but that's our reading; neither file says so.
Three Seconds or 32? The Black Triangle's Missing Hover
The biggest gap between the two black triangle accounts is time. AARO's memo breaks the sighting into three phases totalling about 32 seconds. The FBI statement puts the whole thing at about three.
AARO's phases are a climb of about ten seconds, a "stable hover" of about twenty, and a banking dive into a canyon lasting two to three. The memo never adds them up. The FBI statement goes straight from the climb ("We both observed the object ascend vertically over a ridge line") to the dash, then ends:
"The total duration of the sighting was approximately three seconds."
FBI-UAP-D043, p.2
That three seconds can't just be the final dash, because the agents say they watched the climb too. So one account has twenty seconds of hovering that the other leaves out entirely, and neither document mentions the other.
There's an ordinary explanation for gaps like this. A written statement and a debrief taken later by someone else rarely match line for line. But that is general experience, not something either file says, and it's exactly why AARO put its caveat at the top.
Did the Black Triangle Fly at 1,800 mph?
No speed figure appears anywhere in either black triangle file. The 1,800 mph in several news reports is 1.5 miles divided by three seconds, and those two numbers don't describe a journey.
Both come from the FBI statement. The 1.5 miles is how far away the object was when the agents lost sight of it. The three seconds covers the whole sighting, climb included. Dividing one by the other gives a speed for a trip nobody describes, so it isn't the witnesses' estimate either. AARO's memo is clear on the point: the agents compared it to a military fighter jet, and "No instrumented speed measurement was obtained." The FBI version says only "a very significant velocity".
The other common error is that thermal cameras "couldn't detect" it. Both files say the reverse. AARO records a "spatially uniform thermal signature", and the FBI writer says it "appeared hotter than ambient temperature".
FBI Black Triangle Images: Composites, Not Photographs
The nine images in the FBI black triangle file are not photographs of the object. They're one landscape photograph with a black shape pasted in at a different spot on each page.
Pages 3 to 11 have no captions, and neither file says who made them or when the background was taken. In order, the shape climbs edge-on, turns into a flat triangle above the ridge, banks, and shrinks into the valley. That's AARO's three phases, drawn out. It is a reconstruction of what the agents described, and it's worth nothing as evidence of the object itself. The snow on the distant hills and the bright daylight suggest the base photo wasn't taken at late dusk in June, though that's our observation, not the file's.
Was There a Second Black Triangle Sighting the Next Evening?
The Pentagon's release notes say AARO's memo records "a secondary observation on the following evening". The released memo has no such passage. It covers one evening and the next morning's canyon search, and stops.
There is a candidate, and it was already public. An FBI statement from the Pentagon's fifth release in August, FBI-UAP-D033, carries the same "Unidentified Aerial Object Observation Report" heading and the same phrase, "thermally elevated aerial object". At about 2100 hours, a special agent wrote:
"I observed a thermally elevated aerial object in the same general western sector and along a similar heading as the object observed the previous night."
FBI-UAP-D033, PURSUE Release 5
That object was about two ridge lines further west, flying south, and the writer judged it about half the size of an Army Black Hawk filmed for scale. The June triangle rose over a western ridge and went off to the southeast, so D033 fits. That link is our inference. No document connects the two, and D033 gives no date beyond 2026.
Don't take it further than that, either. The Pentagon's notes also describe a "sensitive national security site in the western United States", the same phrase used for the 2023 orbs launching orbs Western US event. Nothing released says the two are the same site.
What Was the Black Triangle? What the Files Don't Say
Neither file identifies the black triangle. The agents' first words for it were "a delta wing drone", while AARO records their view that a drone that close would have been heard.
AARO calls it an "unidentified craft" throughout. Its collector's note says the agents have "extensive operational experience" around unmanned aircraft, and that on that hilltop even a small military drone "operating at a distance of 1.4 miles would have been clearly audible". Two things limit that. The hearing test applies to the near end of a 1.4 to 3.2 mile range. And the agents judged the size against "the trees along the ridge line behind it", which only works if the object was at the ridge.
It's also much smaller than the triangles in earlier files. Our black triangle UFO files page covers FBI interviews describing triangles of 200 to 500 feet, including the Bagram triangle. This one was 9 to 15 feet across and unlit.
An unlit shape above a ridge isn't a planet or a satellite, but plenty of dusk sightings are.

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. Binoculars are the first step for anyone trying to put a name to something low over a ridge at dusk.
A wide view makes it easy to find a small dark shape fast, and 50mm lenses hold it against a fading sunset sky.
Made to be grabbed in a hurry and carried over rough ground, which is how the agents used theirs.
More magnification for something a mile or more away. Brace it or use a tripod and it will show the outline of a distant aircraft or drone.

Binoculars were the first thing these agents reached for, and they're the right first tool for anyone. Our binocular astronomy guide shows how to hold them steady on something low and moving.
