Bayan-Kara-Ula Mountains UFO Sighting, 1965 — FBI Files
FBI records from 1965 detail an unidentified object sighting in the Bayan-Kara-Ula Mountains alongside findings of ancient, patterned stone discs.
Historical Context and Incident Overview
In 1965, within the remote and rugged terrain of the Bayan-Kara-Ula Mountains, situated along the border of China and Tibet, U.S. government investigators documented an unidentified-object incident. The details of this encounter remained classified for decades, only reaching public view on May 8, 2026, through the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). This case originated during the height of the Cold War, a period characterized by intense aerial surveillance and heightened sensitivity toward any unidentified movement in high-altitude or border regions.
The investigation of this specific event fell under the purview of the Federal Bureau of Investigation. During this era, the Bureau maintained standing protocols for the protection of vital installations, which required various field offices, including those in Knoxville, Albuquerque, and Los Angeles, to route UFO reports directly to headquarters. This administrative process mirrored the workflows of the Air Force’s Project Blue Book and its predecessors, which sought to categorize aerial phenomena that could potentially represent technological threats or atmospheric anomalies.
Archaeological Findings and Documented Evidence
The released documentation contains information regarding anomalous archaeological discoveries found within the mountain caves. For a period of twenty-five years, archaeologists exploring these subterranean sites identified 716 stone discs characterized by spiral grooves and unreadable patterns. These discs, which date back several millennia, were subject to theories suggesting they served as a record of spacecraft visits occurring approximately 12,000 years ago. The research surrounding these artifacts was initially suppressed by the Peking Academy of Pre-History.
The physical description of these objects provided a unique parallel to modern technology. According to the files, each disc features a central hole from which a double groove spirals outward toward the circumference, a structure noted for its similarity to a gramophone record. The text within the file also includes the assertion that the Dropas descended from the clouds utilizing gliders. While the document provides these specific details regarding the discs and the purported visitors, the total number of witnesses to the 1965 aerial incident is not specified in the released record.
Analysis of the Phenomenon
The witnesses involved in the 1965 sighting described the unidentified object as being disc- or saucer-shaped. Such descriptions were common in mid-century aerial reports and often prompted investigations into whether the object was a known man-made craft or a natural phenomenon. In the context of the 1960s, investigators frequently evaluated such sightings against a list of conventional candidates. These included experimental aircraft, weather balloons—specifically those associated with the Project Mogul series from the late 1940s—and various atmospheric optical phenomena such as sundogs or lenticular clouds. Additionally, astronomical objects like the Moon, Venus, or meteors appearing near the horizon were often considered as potential explanations for disc-shaped sightings.
Current Status of the Case
As of the current assessment, all records released under the PURSUE program are designated as unresolved by the All-domain Anomaly Resolution Office (AARO) by default. The federal government has not issued a definitive conclusion regarding the nature of the 1965 event. There has been no official determination that the incident was the result of anomalous activity, nor has there been a conclusion that the event was caused by conventional means. The possibility of both anomalous and conventional origins remains open within the official archives.
