Background

A UFO/UAP incident extracted from page 93 of 65_HS1-834228961_62-HQ-83894_Section_10, a declassified FBI vault file released by the Department of War on May 8, 2026 as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).

What the file records

A Soviet writer discussed research into extraterrestrial visitations, referencing a Chinese archaeologist’s theory of spacecraft visiting Earth 12,000 years ago. The writer noted that expanding knowledge of the universe often reveals more mysteries than answers. The research involved stone discs found in caves inhabited by the Ham and Dropa tribes.

Witnesses on file: Vyacheslav Zaitsev.

Verbatim from the file

“Expanding knowledge about the Universe usually means more puzzles than discoveries.”. “A report by a Chinese archaeologist startled the world when it was published in 1965, for he had out of old bits of knowledge pieced together an amazing theory of space-ships on a visit to the earth 12,000 years ago.”. “The caves high up in the Bayan-Kara-Ula Mountains are inhabited by the Ham and Dropa tribes — frail, stunted men averaging four feet two inches in height.”

Status of the case

The page-level assessment recorded in the file is: no agency assessment. All records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office unless otherwise stated, meaning the federal government has not concluded the events were anomalous, has not concluded they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of this period include experimental aircraft, weather balloons (especially the Project Mogul series), atmospheric optical phenomena, and astronomical objects.
