New Pentagon UAP Files Release Details 'Evidence of Unintended Injury to Human Observers'

The US Department of War has released the sixth tranche of declassified unidentified anomalous phenomena files, including a 2010 report that cites 'evidence of unintended injury to human observers by anomalous advanced aerospace systems.'

The release was published in the United States on Friday, 18 September 2026, through the department's Presidential Unsealing and Reporting System for UAP Encounters, known as PURSUE.

The archive says the files concern unresolved cases for which the government has been unable to make a definitive determination about the nature of the observed phenomena.

The latest batch contains 72 files, 56 documents, 15 videos and one audio recording. The Department of War said further material would be published on a rolling basis.

The released material does not provide a definitive determination that any UAP were extraterrestrial craft.

Pentagon UAP Files Include Human Injury Report

The 2010 document was one of 37 Defense Intelligence Reference Documents, or DIRDs, included in the latest release. The reports were produced under the Advanced Aerospace Weapon System Applications Program, or AAWSAP, alongside programme records dating from 2008 onward.

They examined subjects including warp drives, wormholes, antigravity, negative-mass propulsion and invisibility cloaking.

Many of the AAWSAP documents had already been released through earlier Freedom of Information Act disclosures, including 37 of the 38 DIRDs commissioned under the programme. The new release brings those documents together in the PURSUE archive alongside AAWSAP's contracting and administrative records.

The 38-page report on anomalous acute and subacute field effects on human biological tissues examined what it called 'evidence of unintended injury to human observers by anomalous advanced aerospace systems.' That wording is striking, but the document is a historical intelligence study rather than an independently verified finding that UAP caused human injuries.

One case discussed in the report concerned three people described as previously fit and active who were said to have been exposed to an anomalous aerospace-related event. The report attributed symptoms including skin reddening, hair loss and other medical effects to the incident.

It said one of the three had shown 'signs of radiation illness' and, over subsequent years, 'signs of malignant transformations.' It presented these claims as part of its historical case analysis, the released material does not independently verify the medical assertions.

The account appears in a historical intelligence study and is not an independently verified medical finding. The document's conclusions should therefore not be treated as proof of what caused the alleged injuries or whether the account meets modern evidentiary standards.

That distinction matters. UAP files can quickly move from cautious government language to sweeping online claims. The gap between 'unidentified' and 'extraterrestrial' remains enormous.

A 1952 Air Force Voice Returns

The batch also includes an audio recording of a presentation delivered by United States Air Force Captain Edward J. Ruppelt on 26 March 1952. Ruppelt later headed Project Blue Book, the U.S. Air Force programme that investigated UFO reports from 1952 to 1969.

In the recording, Ruppelt discusses technical methods including diffraction-grating photography and the synchronisation of radar scopes with visual observations. He said the Air Force had about 800 cases on record and that roughly 20 per cent were reports from what he described as reliable observers for which no conclusion could be drawn.

'We've gone through these reports and come up with the fact that about 20% are very good reports offered by very reliable people and are just absolutely no conclusions can be drawn,' Ruppelt said.

The statement has drawn renewed attention because of its language about credible observers and unresolved cases. The recording predates the well-known Washington, D.C., sightings of July 1952 by several months.

That chronology has not stopped the recording from being folded into social media discussions about the capital's reported radar and visual sightings. History, online, is often edited for dramatic effect.

Another file concerns the Tremonton, Utah, film recorded on 2 July 1952. The footage shows a group of small white objects in a blue sky. Project Blue Book studied the film and considered both pillow balloons and seagulls as possible explanations, later Air Force assessments settled on seagulls.

New Files Add Policy Context

The latest release follows earlier batches issued on May 8, May 22, June 12, July 10 and Aug. 7, 2026. Across the series, the files have combined historical records, previously available material and more recent military footage.

One video, recorded by an infrared sensor aboard a U.S. military platform in 2025, shows what the accompanying report describes as six small spherical objects. A U.S. Central Command mission report characterised the objects as seemingly agile and frequently changing direction. The reporting operator estimated their speed at 480 miles per hour, but the released material does not establish that figure as a confirmed measurement.

The wider policy picture also shifted in September, when the Department of War announced a legal waiver establishing an authorised mechanism for covered personnel and contractors to provide UAP-related national defence information to designated PURSUE representatives.

The department said the waiver applied to current and former service members, civilian personnel and contractors who held or had previously been granted access to UAP-related national defence information. It described the authorisation as limited to communications directed to official PURSUE representatives.

For now, the Pentagon UAP files offer more historical material, more unresolved observations and a clearer view of the government's attempt to organise its archive.

They do not provide conclusive evidence that alien craft are visiting Earth. They do, however, show that some historical reports remain unresolved and that a 2010 intelligence study examined alleged human effects associated with anomalous aerospace events.
