Project 10073 Record Card — Calhoun, Louisiana, 14 October 1958

On 14 October 1958, at approximately 0640Z, a civilian witness—a 35-year-old geophysicist employed by the Atlantic Refining Company—observed an unidentified aerial phenomenon while driving east toward Monroe, Louisiana, two miles west of Calhoun. The witness reported seeing a single, brilliant, bluish-white cylindrical object. The object appeared to be the size of a match head held at arm's length and followed a steady flight path from north to south with a downward trajectory. The observation lasted between two and three seconds. The witness noted that the object emitted small sparks or filaments of light and left a trace of green light when it extinguished. No sound was audible during the event. The witness was driving at the time of the observation. Official follow-up by Major Henry B. Tyra, Jr., an intelligence officer with the United States Air Force, confirmed that the Memphis Control Center and Monroe Radio reported no military or civilian air traffic in the area at the time of the sighting. Weather conditions were reported as clear with 15 miles of visibility. In his assessment, Major Tyra noted that the specific visual characteristics of the object—namely the absence of an orange light or a tapered tail—tended to discount the probability that the object was a meteorite. The report was processed under Project 10073 and documented via teletype and a standard record card.
