This document is an Air Intelligence Information Report (AF Form 112) dated 16 July 1953, concerning a sighting of an unidentified flying object in Opportunity, Montana, on 14 July 1953. The report details an observation made by three individuals: Stanley Cutler and Mr. and Mrs. Alfred [illegible]. The witnesses reported seeing a single, round, whitish-yellow object that appeared to be shiny, like a large mirror, and measured approximately four to six feet in diameter. The object was observed moving up and down before disappearing below the horizon. The witnesses were considered reliable by the reporting officer, Captain Paul H. Milliken. The report notes that the weather was clear with no wind at the time of the sighting. Although the Air Defense Command was notified, no interception or identification action was taken. The official conclusion provided by the approving officer is that the object was likely a weather balloon, despite the report itself being marked with an evaluation of 'insufficient data for evaluation.' The document includes a cover memo from the Headquarters Air Defense Command at Ent Air Force Base, Colorado, forwarding the report to the Air Technical Intelligence Center at Wright-Patterson Air Force Base, Ohio, in accordance with Air Force Letter 200-5.
