Incident Overview
In 1954–1974, in an undisclosed location, CIA preserved a documentary record that was declassified and published on June 12, 2026 as part of the third tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).
What the government released
This CIA History Staff document chronicles the complete history of the U-2 and OXCART (A-12) high-altitude reconnaissance aircraft programs from 1954 to 1974, detailing their development, operations over the Soviet Union and other targets worldwide, the famous downing of Francis Gary Powers in 1960, organizational reforms following that incident, and the eventual transfer of operations from CIA to Air Force control. A more redacted version of this document has been available on CIA’s public website.

Status of the case
Records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office, which means the federal government has not concluded the events were anomalous, has not concluded they were conventional, and has not ruled out either possibility. Where AARO has offered a likely source for an item — an infrared sensor aboard a military aircraft, a commercial camera, or a known optical effect — that attribution is the agency’s working assessment rather than a final determination. Conventional candidates such as drones, balloons, flares, satellites, parallax and forced-perspective artifacts, and ordinary aircraft remain on the table for any unresolved case absent better data than a single sensor pass or a witness recollection.
