Project 10073 Record Card — South Pass, Louisiana, 25 December 1957

On December 25, 1957, at 2030Z, a sighting of an unidentified aerial phenomenon was reported at the CG Light Station in South Pass, Louisiana. The witness, BM2 Robertson of the United States Coast Guard, observed a single, round, bright white light for approximately 30 minutes. The object was described as moving in a westerly direction at a speed faster than a star or planet, but without any audible sound or visible exhaust. The witness noted slight variations in the light's intensity before it abruptly flashed out. The observation occurred under clear and calm weather conditions, with the object positioned approximately 25 degrees above the horizon. The report explicitly states that there was no physical evidence, no radar contact, and no interception or identification of the object. Furthermore, there was no known air traffic in the area at the time. The official assessment of the sighting, documented on a Project 10073 record card, concludes that there is insufficient data for a definitive evaluation, primarily due to the absence of azimuth and wind data. However, the report suggests that the object could potentially have been a weather balloon equipped with lights.
