Incident Overview

On October 6, 1953, in Little Diomede, Alaska, the Department of War preserved a documentary record that was declassified and published on October 23, 2026 as part of the seventh tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).

What the government released

This document is an Air Intelligence Information Report (AIIR), a standardized U.S. Air Force reporting form used to record raw information of potential intelligence value for later analysis. The form served as a primary vehicle for U.S. Air Force field intelligence collection throughout the early Cold War, until defense-wide reporting standards were established in the early 1960s.

This AIIR records an October 6, 1953, incident on Little Diomede, Alaska, in which a resident of the island reported observing a light on the southern tip of Big Diomede, U.S.S.R. The report states that the light lasted for several seconds and appeared as though it came from a large flashlight or spotlight. It further describes the light as about the size of a nickel coin held at arm’s length and about the same color as a burning match or dim flashlight.

All descriptive and estimative language contained in this report reflects the reporter’s subjective interpretation at the time of the event. Such characterizations should not be interpreted as a conclusive indication of the presence or absence of any intrinsic object features or performance characteristics.

AARO Comment: The Diomede Islands are situated in the Bering Strait between Alaska and Siberia and constitute the nearest point of territorial proximity between the United States and the former Soviet Union.

Status of the case

This is an archival record, and it should be read as one. It records what a particular office believed, or was willing to commit to paper, on the day it was written — not a present-day finding. The mid-century investigations worked from witness testimony, sparse instrumentation, and the strategic anxieties of the early Cold War, and the great majority of the sightings they catalogued were eventually attributed to aircraft, balloons, astronomical objects, and misidentification. The All-domain Anomaly Resolution Office has made no modern determination about the incidents described here, and the record’s release is not an endorsement of the conclusions inside it. Its value is as evidence of how the United States government investigated the question, and of what it chose to keep.
