The Black Triangle Two Army Veterans Couldn't Explain (FBI UAP Report, 2011)
2026-08-09 · Declassified UAP records
On a summer evening in 2011, two men leaving a driveway watched a massive black triangle glide low over their neighborhood — a car-sized light glowing at each corner, humming as it passed, and gone in ten to fifteen seconds.
The encounter is preserved in an FBI interview report, an FD-302, declassified through the government's UAP disclosure. A large section of the report is blacked out — the witnesses' identities and backgrounds redacted — but two details survived: both men were U.S. Army veterans. One had served six and a half years; the other, twenty-four.
According to the report, they had reached an intersection when one looked up and saw three lights, then the shape behind them: a massive black isosceles triangle flying north, low to the ground, with a car-sized light recessed into each corner. It made a low humming, pulsing sound and left no contrails. One reached for his phone, but by the time he had it out, the object had cleared the treeline and vanished. He estimated it was roughly eight hundred feet above the ground.
Below is the declassified document, redactions intact, followed by the full narration transcript.

FBI FD-302 — Massive Black Triangle (June/July 2011)
On April ██████, 2025 ██████ and ██████ were interviewed by Supervisory Special Agent (SSA) ██████, Special Agent (SA) ██████, and Task Force Officer (TFO) ██████. Also attending the meeting was ██████. After being advised of the identity of the interviewing agents and the nature of the interview, ██████ and ██████ provided the following information:
██████ served six and a half years in the U.S. Army ██████. ██████ served 24 years in the U.S. Army ██████.
On an evening in June or July 2011, it was dark outside when ██████ was leaving his driveway located at ██████ at about 8 or 9 PM. ██████ was with ██████, who was driving the vehicle, and ██████, who was in the front passenger seat. The vehicle was about fifty feet from the driveway and preparing to make a left turn onto ██████. When they reached the intersection, ██████ was looking out window and saw three lights in the sky. ██████ got out of the vehicle, and when he looked up, he saw a massive black isosceles triangle shaped object flying North.
The object had a car-sized white light in each of its three corners that emitted a diffuse glow and were recessed back a bit from the corners. The object was low to the ground, and creating a low humming noise that made a pulsing sound. ██████ told him to take a video, but by the time ██████ got his phone out, the object had flown over the tree line behind the houses to the north, and out of sight. He had seen the object for approximately 10-15 seconds. There were no contrails left behind the object. ██████ felt dumbfounded and awestruck during the experience.
When ██████ observed the object, he was overwhelmed by the size of it and how low it was to the ground. ██████ thought the object may have been 800 feet above the ground, and based on the dimensions of their environment, he estimated the object was 200 feet long and 100 feet wide. ██████ believed the object had more of an equilateral triangle shape, but based on the calculated dimensions, it could have been more of an isosceles triangle. The object was moving slowly and steadily, and he also heard the pulsing sound. ██████ saw the three lights in the corners, but also remembered seeing something in the middle of the triangle that was grayish or graphite colored.
Neither ██████ nor ██████ had a clear memory of the thickness or any other description of the vertical profile of the triangle. They opined that they were initially underneath the triangle and didn't really have a view of its side or vertical profile. They were then temporarily distracted by their unsuccessful attempt to get a phone out to video record the UAP, at the moment when they likely would have had a better view of the back profile.
██████ believed a couple of people in the neighborhood also saw the object. ██████ and ██████ stated they would also try to see if ██████ as well as their neighbors who witnessed the UAP, would be willing to write a statement about their observation, or speak to the FBI about it.

FBI FD-302 (3 pages); interview April 2025 of two U.S. Army veterans regarding a 2011 sighting. Released under the PURSUE UAP disclosure — redactions preserved. · Federal Bureau of Investigation (FBI-UAP-D028)
Full Transcript
It was dark, and they were just pulling out of the driveway when three lights appeared. Then they saw the shape behind them: a massive black triangle, low and slow, flying straight north, a car-sized light glowing at each corner.
A summer evening in 2011. Two men in a car reached the intersection, looked up, and watched it drift over the treeline for ten, maybe fifteen seconds. Low to the ground, and humming, a low pulsing sound. No contrails. One reached for his phone, but by the time he had it out, it was gone.
Here is the FBI's report, and a whole section is blacked out. But look what slipped through the redactions. Both witnesses were U.S. Army. One had served six and a half years. The other, twenty-four. Two soldiers, and neither one could explain what flew over their heads that night.
The FBI kept their names, and most of their story. But not what they saw. A low-humming black triangle, maybe eight hundred feet up, gone in seconds. What do you think it was? Tell me in the comments. Search Case D-28 at ufodata.org to read the file yourself, and subscribe to UFO Data.
