Project 1007 Record Card and Associated Correspondence — Lake Ocoee, Tennessee, April 1960

This document collection details a UFO sighting reported on April 8, 1960, near Lake Ocoee, Tennessee. The primary witness, an employee of the Chattanooga Times, observed a round, reddish-white object with a long trail, described as being the size of a full moon or a basketball held at arm's length. The object moved from the southeast to the northwest, eventually disappearing behind a cloud formation. The witness, who was with another individual, initially speculated that the object might be the Sputnik satellite, but later provided a detailed account to the Air Force. The sighting lasted approximately 15 minutes. The Air Force investigation, conducted by the 2589th Air Base Group and evaluated by the Air Technical Intelligence Center (ATIC), concluded that the witnesses had observed the vapor trail of a high-flying aircraft. The analysis suggests that the object's appearance—specifically its brightness and color change—was an optical effect caused by the aircraft being in direct sunlight at an altitude of approximately 30,000 feet, while the observers on the ground were already in twilight. The report includes official correspondence, a Project 1007 record card, and a personal letter from the witness to the operations officer at Flintstone Air Force Station. The Air Force requested additional details regarding the object's angular size and elevation to confirm their assessment. The final conclusion remained that the phenomenon was an explained event, specifically a high-altitude contrail.
