Project Blue Book Record Card and Teletype Report — Louisville, Kentucky, 21 July 1952

This document consists of a Project Blue Book record card and a subsequent teletype report detailing an unidentified aerial phenomenon sighting that occurred on July 21, 1952, over Louisville, Kentucky. At 2120 EST, two Air Force pilots, Captain James Harvey McGrath and Captain Max Leonidas Moore, observed a single, unidentified object while flying their aircraft at an altitude of 20,000 feet. The object was described as round in shape with a red-tinged color. It remained in view for approximately one minute, maintaining a constant heading of 300 degrees before disappearing. The pilots reported that the object produced no sound, left no trail or exhaust, and was traveling at a speed estimated to be well over 100 miles per hour. At the time of the sighting, the pilots were flying at 410 knots. The report notes that there was a slight haze in the immediate vicinity and a squall line located 60 to 70 miles north of their position. The document explicitly states that there was no physical evidence of the object, no interception occurred, and there was no other air traffic in the area. Both pilots were characterized as reliable and experienced, and the report concludes that no known condition, meteorological or otherwise, could account for the sighting. The teletype was transmitted from the 91st Strategic Reconnaissance Wing at Lockbourne AFB to the Director of Intelligence at HQ USAF, with copies sent to the Air Technical Intelligence Center and SAC at Offutt AFB.
