The Pentagon released its sixth batch of UAP files, containing 71 documents, videos, and audio recordings dating from 1952 to 2025.

The release includes records from a former military program that studied advanced concepts such as warp drives, wormholes, antigravity, and invisibility, although the Pentagon said the studies were reference materials rather than proof that the technologies exist.

One technical report examined injuries that researchers associated with unexplained aerospace events, including symptoms such as skin irritation, hair loss, and possible radiation exposure.

The files also contain military footage of unexplained objects recorded in the Middle East and reports from Colorado law enforcement involving unidentified objects with flashing lights, CBS News has reported.

Historical documents include a 1952 presentation by Air Force officer Edward Ruppelt, who said about 20 percent of hundreds of UFO reports under investigation remained unexplained at the time.
