On September 18, 2026, the Pentagon published its sixth batch of UAP files: 72 items, including 15 videos, 56 documents and one audio recording.

The audio is a March 26, 1952, presentation by Captain Edward Ruppelt, who later ran Project Blue Book, the Air Force’s UFO investigation. Of about 800 cases reviewed, he said, roughly 20 percent remained unexplained after analysis, and those were very good reports from very reliable people.

The release includes the Tremonton, Utah, film shot on July 2, 1952, showing a cluster of small white objects against blue sky. Blue Book’s conclusion was probably seagulls. Analysts have argued over it ever since.

There are also 37 Defense Intelligence Reference Documents from AAWSAP, a Pentagon program that ran from 2008 to 2012, on subjects such as warp drives, wormholes, antigravity and invisibility cloaks. Most were already public. The new versions restore some withheld details, such as which offices produced them. One 2010 paper discusses claimed injuries to people near anomalous aerospace systems. Those are the paper’s claims, not verified findings.

The newest item is a one-minute infrared video from CENTCOM in 2025 showing six small spheres flying in two triangles. The mission report calls them agile and estimates their speed at 480 mph.

EarthSky’s review summed up the series so far: a mix of old and new material, and still no smoking gun.
