Summary
On the night of February 26, 1961, a U.S. Air Force master sergeant stationed at Tyndall Air Force Base in Florida reported seeing a bright, moving object in the sky. Master Sergeant Henry J. Lacour first spotted the object at 1935 (7:35 p.m.) from Capehart Housing on the base. He described it as elliptical in shape, roughly the size of a grapefruit, and very bright, similar in appearance to a star. The object seemed to travel steadily from west to east, though Lacour noted it appeared to bounce or stop every five seconds. He initially observed it at an angle of 45 degrees above the horizon and in a direction about 295 degrees (roughly northwest). After about ten minutes of observation, the object seemed to stop and then disappeared entirely in a direction roughly 60 degrees (northeast). The sky was clear and lit by moonlight at the time.
Lacour called over Captain Allan E. Aaronson and Captain Norman R. Smedes, who also observed the object during part of his sighting. The weather was fair and clear with good visibility.
In its analysis, the Air Force noted that the planet Venus was visible that evening at a magnitude of negative 4.3, making it as bright as Venus ever gets. Venus was positioned low on the horizon in a direction matching the one Lacour reported. The file states that objects distorted by atmospheric refraction (the bending of light as it passes through the atmosphere) can appear to move in unusual ways. The Air Force evaluated the case as unidentified, though the comments section suggests the object was probably the planet Venus. However, the official conclusion checkbox on the case card was not marked with a specific determination. The full case file, comprising 8 pages as held by the National Archives, is reproduced below.
