Pentagon Documents Detail Silent, Rapidly Accelerating Black Triangular Object Near Western U.S. Site

By Ravi Hari

Pentagon documents released under a Trump‑signed executive order describe a June encounter involving federal agents and a large, black triangular object near an unidentified national security site in the western United States. The object reportedly climbed vertically 200 to 300 feet, hovered silently for about 20 seconds, then accelerated away at a speed comparable to a military fighter jet, disappearing within seconds. Agents noted no visible exhaust, a consistent thermal signature under infrared observation, and a matte‑black, featureless exterior. The All‑Domain Anomaly Resolution Office memorandum and an FBI statement are included in the 28 PDFs, but the documents do not identify the object or explain its operation. Witness accounts describe the craft as a non‑reflective, delta‑wing‑style drone with an estimated wingspan of 9 to 15 feet, depth of 6 to 9 feet, and thickness of 1 to 2 feet. The report highlights the object's vertical ascent, silent hovering, rapid acceleration, lack of exhaust, and steady thermal signature, though it does not confirm any extraordinary technology or provide independently measured velocity data.
