Newly declassified government files released Friday, Oct. 23, describe black triangle-shaped objects observed flying at speeds of up to 1,800 miles per hour over secret U.S. military bases on at least three separate occasions in the past year [1].
The files state that the objects traveled without vapor trails and that the exact dates and locations of the sightings were redacted for security reasons, said officials [4].
The release is part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE) [4]. The tranche marks the seventh batch of documents made available to the public under the program, and more releases are planned, government officials told a small group of reporters late in October.
The documents state that observers reported the triangles moved without making sound and showed no exhaust gases [4]. The sightings have raised concerns about the technology observed and about the objects' presence over top secret sites where the U.S. government tests new technology.
Sighting Reports and Technical Details
An FBI report included in the release said observers noted one object moving 1.5 miles in three seconds, a speed calculated at 1,800 miles per hour [4]. Sketches released by the government show a black, triangle-shaped object over a mountainous area; no photographs were provided [4].
Observers reported that the triangles made no sounds and showed no exhaust gases, according to the files [4].
A thermal scan reportedly produced a consistent heat signal, unlike an airplane or drone that would register higher heat around certain areas such as an engine [4].
Two primary witnesses reported no physiological effects such as disorientation, nausea, headaches, memory gaps, or other anomalous sensory phenomena, according to a Department of War memo [4].
The News Nation reported that the object flew at an elevation of 200 to 300 feet and measured about nine feet long, with a wingspan of approximately 13 feet [1].
Attribution and National Security Concerns
A War Department memo described another triangle sighting as having "a continuous (seamless), featureless surface lacking any discernible structural discontinuities, propulsive apertures, intake structures, aerodynamic control effectors, or cockpit features [4]."
Government officials ruled out the possibility that the objects were American technology [4]. Officials expressed skepticism about whether the objects were a foreign asset, citing no known countries with those advanced technical capabilities, according to the documents [4].
The sightings raised concerns about the technology observed and about the objects' presence over top secret sites where the U.S. government tests new technology [4].
As the Guardian reported, two senior military observers watched the object flying at an extraordinarily high speed over a sensitive site in the western U.S. earlier this year [2].
The documents state that it remains unclear whether the triangular objects were from other nations [4]. No files released to date have offered definitive proof of alien life, officials said.
Release Process and Prior Disclosures
The Oct. 23 release marked the seventh tranche of files made available to the public, and more releases are planned, government officials told a small group of reporters [4].
Previous releases have included other reported sightings of unidentified flying objects (UFOs), but none of the files have offered definitive proof of alien life [4].
The current batch includes documents from the Pentagon, the FBI, the CIA, the Department of State, and the Executive Office of the President, with records dating from 1950 to 2026 [3].
The release process has drawn comparisons to earlier disclosures.
Other Documents in the Tranche
The release contains documents about the History Channel reality show Skinwalker Ranch, a 512-acre property in Utah described in the files as a reported hotspot for UFO sightings and unexplained phenomena [4]. The files state that government officials collected hair samples from the ranch in 2010 after a rancher said a skinwalker was spotted and his dogs chased it through a barbed-wire fence; the hair underwent DNA analysis [4].
People on the property described seeing a "black shadowy figure" and reported "dog-like creatures running on two legs, unnatural animalistic howling/screaming, little people, prehistoric birds and a maggot which measured about 8 feet long," according to the files [4].
As of May 2010, officials had interviewed at least 25 people, including Native Americans in the region, local police, ranchers, members of the Mormon church, and the director of the local Fish and Wildlife service [4].
The release also examines unidentified sightings around California's Catalina Island and includes a NASA document from the 1960s offering guidance on what to do if a person comes in contact with space fragments [4].
Unresolved Questions
It remains unclear whether the triangle objects were from other nations, according to the redacted files [4]. The files state that officials expressed skepticism about whether the objects were a foreign asset, citing no known countries with those advanced technical capabilities.
No files released to date have offered definitive proof of alien life, officials said, and additional tranches are expected [4].
The release leaves unresolved the question of what the black triangles were and who, if anyone, operated them. Officials said the sightings raised concerns about the technology observed and about the objects' presence over top secret sites where the U.S. government tests new technology.
Government officials have not announced a timeline for the next tranche of files. The documents released Friday did not include photographs of the objects, only sketches showing a black, triangle-shaped object over a mountainous area [4].
