Incident Overview
On August 27, 1952, in Sassari, Italy, 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 August 27, 1952, incident near Sassari, Italy, that was reported in the local Italian press the following day. The U.S. Air Attaché in Rome relayed the translated newspaper account to the Air Force in November 1953 and later interviewed the individual who made the initial report, Professor Giovanni Battista Sias. Sias described observing a brilliantly luminous sphere, slightly larger in apparent size than the full moon, with a green-blue color, silvery brightness, and metallic streaking on its right side. He reported that it moved from east to west at very high speed, intermittently disappearing and reappearing while leaving behind a narrow luminous trail or ribbon. The preparing officer characterized Professor Sias as intelligent, pleasant, and eager to share his account.

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.
