Unidentified

Summary

On the evening of May 9, 1961, at 7:45 p.m., military personnel and a civilian observer at Tyndall Air Force Base in Florida watched two bright objects moving across the night sky. The objects were described as slightly elliptical in shape, about the size of a grapefruit, and resembling a star in color. The main observer, Master Sergeant Henry J. Lacour, watched from Capehart Housing on the base. He was joined by Technical Sergeant Joseph T. Terlesky, Captain Allan E. Aaronson, and a civilian from Panama City, Florida.

The objects moved in different patterns. The first object traveled from southwest to northeast, heading initially at about 250 degrees (roughly west-southwest). The second object moved from southwest to southeast and later changed direction to 215 degrees (roughly southwest). Lacour watched for about twenty minutes while Terlesky observed for only five to ten minutes. Both objects eventually faded from sight. Notably, Lacour believed he was observing the satellite Echo, which was expected to pass over the area around that time that evening.

The Air Force investigation centered on a key detail: the speed and behavior of a high-flying aircraft closely matched the velocity of the satellite Echo. The investigators noted that past reports from this witness showed he became "very excited" when the subject was UFOs, which could have led to misidentification. The analysis sheet suggested that what was observed was probably a passing aircraft that was either mistaken for or confused with the Echo satellite. Weather conditions at the time were fair and clear. The Air Force concluded that the objects sighted were probably a high-flying aircraft, making them explainable rather than truly unidentified.
