341_110677 Numerical File, 5-2500

The Department of War's May 8, 2026 UAP release identifies this file as an Air Intelligence Information Report dated October 14, 1955, concerning an eyewitness account of the ascent and flight of unconventional aircraft in the Trans-Caucasus region of the USSR.¹ The PDF is a scan of a previously classified Air Force intelligence report, not a later narrative summary, and the release metadata places the record in Azerbaijan.¹

  What the Report Contains

The scanned report form is marked as an Air Intelligence Information Report and carries crossed-out Secret and No Foreign Dissemination markings, with a declassification stamp on the surviving copy.² Its subject line describes an "unconventional aircraft" sighting in the USSR, and the summary says the aircraft's unusual feature was its ability to rise vertically and then transition into horizontal flight.²

The report attributes the central observation to Senator Richard Russell, who was traveling by electric train in Soviet Azerbaijan at about 2145 hours on October 12, 1955.² According to the report, Russell saw an object rise near the rail line, moving almost vertically and leaving an exhaust or vapor trail below it. The scan states that the train was moving at the time and that the object was seen through the train window before it disappeared into the night.²

  Witness Chain and Corroboration

The body of the report is careful about who saw what. It names Russell as the first observer and then records corroborating accounts from Lt. Col. Hathaway and interpreter Ruben Efron, both traveling with the delegation.² Hathaway reportedly saw the first object only after Russell called attention to it, but he also observed a second object rise and then take a horizontal course. Efron is described as seeing the first object cross above the train before it disappeared.²

That witness chain matters because the document is not merely a single-person anecdote. It preserves a contemporaneous U.S. Air Attache reporting path, identifies multiple delegation members, and separates the first sighting from later observations. The report also notes limits: the observers were on a moving train at night, the sighting lasted briefly, and the file does not identify the objects.²

  Why This File Matters

This record is useful because it captures a Cold War-era aerial anomaly in the format of an intelligence cable/reporting form rather than in folklore or retrospective press coverage. The report does not conclude that the aircraft were extraterrestrial, and the Department of War release metadata does not add an explanation. What it does establish is narrower and more valuable: a named U.S. senator and members of his party reported seeing unconventional flight behavior in Soviet territory, and that account was formalized within Air Force intelligence channels two days later.¹²

The May 2026 release context should therefore be treated as provenance, not as the substance of the case. PURSUE explains why the file became publicly accessible in this release set; the evidentiary core remains the October 1955 Air Intelligence Information Report and the specific observations recorded inside it.¹²
