As the federal government releases another tranche of UAP records, a new report says potentially significant Air Force footage from Colorado remains classified.

Two classified videos allegedly depicting a large, black triangular unidentified anomalous phenomenon over a Colorado military installation remain unavailable to the public despite a widening federal effort to release government UAP records.

The New York Post reported Aug. 8, 2026, that the videos were recorded on consecutive nights in 2023 by a service member using a personal cellphone. Citing unnamed sources familiar with the footage, the Post described the object as approximately 100 feet across and said it appeared to maneuver over nearby mountains and become obscured by clouds. The newspaper reported that the videos are held by the Air Force Office of Special Investigations in Colorado.

Those details cannot currently be independently verified. The videos have not been publicly released, and Unknown Country cannot confirm the reported size, appearance, behavior or origin of the object from the available evidence.

The report comes as the federal government expands its UAP disclosure effort. The U.S. Defense Department’s Presidential Unsealing and Reporting System for UAP Encounters, or PURSUE, released its fifth tranche of records Aug. 7, 2026. The program was established following a February 2026 federal directive to identify, review, declassify and release government records concerning UAP, UFOs and possible extraterrestrial life. According to the department, the effort involves dozens of agencies and potentially tens of millions of records.

Importantly, the department explicitly states that materials placed in the PURSUE archive are unresolved cases — incidents for which the government cannot definitively determine the nature of the observed phenomenon, sometimes because sufficient data are unavailable.

The fifth release includes 130 megabytes of documents and 513 megabytes of video, following four previous releases dating to May 8, 2026

Whether the reported Colorado videos will eventually enter that public archive remains unknown. Their reported existence, however, illustrates a central question surrounding the new disclosure effort: how much significant UAP evidence remains classified even as the government promises greater transparency?
