Newly declassified US government files have detailed reports of mysterious black triangular objects over US military bases, with witnesses estimating that one travelled at speeds of up to 1,800 miles per hour. The reported sightings have raised questions about national security and the origin of the unidentified aerial phenomena, although the released documents do not establish what the objects were.
The accounts appeared in a new batch of government records released under US President Donald Trump’s initiative to disclose information about unidentified anomalous phenomena, or UAPs. According to reports, the sightings occurred at least three times during the previous year, but specific dates and locations remain redacted for security reasons.
Sketches accompanying the records depict triangular objects, but no photographs of the reported encounters were made public.
Witnesses Describe Unusual Speed and Structure
An FBI report cited in the released records describes witnesses observing an object travelling approximately 1.5 miles in three seconds, equivalent to around 1,800 mph.
The witnesses estimated its wingspan at nine to 15 feet, its depth at six to nine feet and its thickness at one to two feet. They reportedly described the object as silent, with no visible exhaust.
Thermal scans allegedly showed a consistent heat signature without clearly identifiable hot spots associated with conventional engines or propulsion systems.
A separate Department of War memo described another triangular object as having a seamless, featureless exterior. According to the document, it had no visible propulsion openings, air intakes, aerodynamic control surfaces or cockpit.
The two primary witnesses reportedly denied experiencing physical effects such as headaches, nausea, disorientation or memory gaps.
Sightings Raise National Security Questions
The reported encounters have attracted attention because the objects were allegedly observed above sensitive military locations where advanced technologies are tested.
According to published accounts of the files, officials ruled out the possibility that the objects represented American technology. However, the available documents do not establish their origin or confirm whether they belonged to a foreign government.
The redaction of locations and dates also limits independent assessment of the incidents. Their reported speed and unusual characteristics remain witness descriptions rather than independently verified evidence of extraordinary technology.
US Releases Another Batch of UFO Records
The disclosure reportedly marks the seventh batch of government records released under the administration’s initiative to increase transparency surrounding UAP encounters.
Officials have indicated that further disclosures are expected. Earlier records have included reports from military personnel and other witnesses, but the documents released so far have not established definitive evidence of extraterrestrial life.
The black triangle sightings remain unexplained. The available accounts do not determine whether the objects were experimental aircraft, foreign technology, misidentified phenomena or something else.
