Project 10073 Record Card — 1 September 1958, Dallas, Texas

On 1 September 1958, at 1820 hours, an observer in South Dallas, Texas, reported sighting two round, grey objects flying approximately two minutes apart. The objects were observed moving in a south-southeasterly direction before disappearing behind clouds. The duration of the observation was estimated at 45 to 60 seconds. The weather conditions were reported as clear with few scattered clouds, bright sunshine, and no haze. The observer, described as a reliable individual with an interest in astronomical observation and 'Moonwatch' activities, noted that the objects followed a course similar to that of Sputniks and their rocket carriers. A jet aircraft vapor trail was visible at the time, though the aircraft itself was not seen. The reporting officer, 1st Lt. Frederick F. Swartz of the 745th ACWRON, suggested that the objects were likely F8U-1 Crusader jet fighters from the nearby Chance-Vought aircraft plant. It was noted that these aircraft are painted dark and would be noticeable in a clear sky if close enough. The report was processed through military channels, including the 745th ACWRON, ADC, and ATIC.
