PENTAGON UFO FILE · DOCUMENT · DOW-UAP-D156Air Intelligence Information Report, Guam, 1956
This four-page Air Intelligence Information Report (IR-7-57) was prepared by Capt. Alan G. Pound of the Far East Air Forces’ Air Technical Intelligence Liaison Office and dated 8 February 1957, with an evaluation of B-4. It relays a message from the Seventh Air Force (Advanced) on Guam about a sighting at 1610Z on 31 December 1956, and was approved for the Director of Collections.
The pilot’s account
The witness was an alert pilot of the 41st Fighter-Interceptor Squadron, flying an F-86D in the Guam radio range holding pattern at night; the squadron’s intelligence officer rated him very reliable. He described one round, white light about the size of a dime that stayed on for some four seconds, blinked, and repeated. Taking it at first for a B-47, he turned toward it, but he could not close on it and it kept turning with him. By his account it passed between him and Agana, ran south about ten miles, climbed to roughly 30,000 feet and circled over him, came back again after he lit his afterburner, and was still with him when low fuel sent him back to Andersen Air Force Base. The contact lasted about ten minutes. No silhouette was seen, there was no other known traffic, and the squadron added no comment.
The balloon check
Because the sighting resembled earlier balloon reports, the office asked about lighted balloons and learned the Weather Bureau had launched one from the Navy communications station at 1432Z; it was last tracked at 20,000 feet at 1500Z, rising more slowly than normal. The pilot, questioned again, rejected a balloon because the light maneuvered and accelerated past him. Pound’s comment is cautious: a normal balloon would have been far higher, and only a malfunction that kept it low could possibly explain the report. A small location sketch is included. The file does not record a final verdict. Compare the radar-only bomber report DOW-UAP-D155.
The official description
From war.gov/UFO, released October 23, 2026, quoted in full
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 a December 31, 1956, incident in the vicinity of Guam in which the pilot of a U.S. Air Force F-86D aircraft reported observing an unidentified aerial blinking light. The report notes that a lighted weather balloon had been launched before the sighting and states that, if the balloon had malfunctioned and remained at a relatively low altitude, it could possibly explain the reported object. It also indicates that the preparing officer did not regard the balloon explanation as sufficient unless that condition applied.
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.
