Project 10073 Record — Sighting in Tulsa, Oklahoma, 1 September 1966

This document contains a Project 10073 record regarding a UFO sighting reported by three witnesses in Tulsa, Oklahoma, on the night of 1 September 1966. The primary witness, a cadet in the Civil Air Patrol, wrote to Major H. Quintanilla, Jr. at Wright-Patterson AFB to report an unusually bright, round object with a pulsating light that shifted from red to white. The witness described the object traveling in an ESE direction, noting that it appeared to dim, brighten, and at one point seemed to enter a large black object before disappearing. The total duration of the observation was estimated at five minutes. The Air Force conducted a detailed study of the report and concluded that the witnesses had observed the ECHO I satellite. Official correspondence from the Office of Information, signed by Lt. Colonel George P. Freeman, Jr., informed the witness that the observed light fluctuations and the illusion of zig-zag motion were consistent with satellite observations and were likely caused by the twinkling of stars and meteorological conditions. The file includes the original sighting record, internal Air Force routing and coordination memos, the formal response to the witness, and a hand-drawn sketch provided by the witness depicting the object entering a larger black shape.
