New Pentagon UFO files released today (September 18) revive the eerie 1952 Tremonton “flying saucer” mystery, with newly digitised footage showing 10 to 14 bright objects circling in a clear sky
Freshly declassified Pentagon UFO files have reignited one of America’s most famous “flying saucer” mysteries – with newly digitised footage showing clusters of bright objects sweeping through a crystal-clear sky.
The U.S. The Pentagon released its sixth batch of declassified UFO/UAP files today (September 18) as part of a sweeping transparency push.
The drop includes internal documents and video linked to the Tremonton, Utah incident – a chilling sighting from July 2, 1952 captured by a Navy photographer while on holiday with his family. The newly released footage shows 10 to 14 bright objects in a clear blue sky, appearing to drift and wheel in a loose circular pattern.
The sighting was reported by Delbert C. Newhouse, a U.S. Navy Warrant Officer with a photography specialism, who said he spotted 12 to 14 reflective objects and filmed them on colour motion-picture stock using a handheld Bell & Howell Auto Master camera.
In the file, Newhouse is described as honest and dependable – and a highly experienced operator, with more than 1,000 hours’ experience in aerial photography.
Newhouse also gave a striking description of what he believed he was seeing, saying the objects looked like “two discs stacked on top of each other” – the classic “flying saucer” shape that has haunted UFO lore for decades.
The newly released files contain dozens of documents, images, and video and audio recordings from multiple government agencies, alongside eyewitness testimony and first-hand accounts describing unexplained sightings, Fox 5 DC reported.
The Tremonton video was investigated under the U.S. Air Force’s now-infamous Project Blue Book, set up to assess the nature and origin of unidentified flying objects.
Pentagon documents show analysts weighed up multiple explanations for what appeared in the film, including sunlight glinting off birds or balloons, or even a mirage effect – but the case remained murky.
Later reviews, the file says, “became more confident that the objects were seabirds reflecting sunlight, citing identifiable seabirds and similar films showing seabirds as bright points of light under comparable conditions”. But the new release also includes details of a key meeting held months after the sighting – including the involvement of balloon specialists and a major American firm.
The Pentagon file includes imagery of pillow balloons supplied by General Mills Research Laboratories, which was shared after experts examined the footage.
And the newly declassified assessment includes this full statement: “In late December 1952, Project Blue Book personnel, balloon specialists, and representatives from General Mills reviewed the Tremonton footage,” the Department of War states.
“The group’s consensus was that the objects closely resembled pillow balloons in flight and behaved consistently with that explanation. One General Mills representative was less convinced, noting that the objects appeared somewhat too bright and seemed to maneuver too rapidly.”
That lingering doubt helped keep the case in the “unresolved” pile – partly because investigators said the film lacked fixed reference points and enough detail to make a definitive identification. The broader release contains 71 files in total – 55 PDFs, 15 videos and one audio file – spanning alleged incidents from 1952 to 2025.
Among the highlights are documents tied to the Advanced Aerospace Weapon System Applications Program (AAWSAP) – a secretive, nearly $22 million (£16.48 million) government effort contracted to Bigelow Aerospace, exploring far-out concepts including warp drives, wormholes, invisibility cloaking and spintronics.
The batch also includes more recent military and civilian material, including a 2025 video submitted by CENTCOM said to show six small spherical objects changing direction rapidly over the Middle East, and mobile phone footage from Colorado in October 2023 showing a silent object flashing red, blue and green lights.
The Pentagon’s All-domain Anomaly Resolution Office (AARO) reiterated that the cases remain labelled “unresolved” due to a lack of complete data – and stressed there is still no verifiable evidence linking the sightings to extraterrestrial technology.
