SAN ANTONIO, TEXASDecember 1952

On December 21, 1952, a driver in San Antonio, Texas saw an unusual object in the night sky while traveling on Freese-Tilden Highway. The witness was alone in his car when he noticed a pale green, round light appear in the sky at about 1 o'clock in the direction he was facing. The object reminded him of a small ball launched from a Roman Candle (a type of firework). It hung at an elevation of roughly 15 degrees above the horizon and moved quickly toward the two o'clock position in a slightly downward path.

The object's speed seemed noticeably faster than any jet aircraft the witness had observed, but notably slower than a meteor. After traveling for about one and a half seconds, the object made a sharper downward turn while seemingly losing both speed and brightness. The green light then faded and the object disappeared from view at approximately 10 degrees above the horizon. The entire sighting lasted only a few seconds. The witness noted that fair weather prevailed at the time, the sky was clear, and no sound was heard from the object.

The Air Force investigation concluded the sighting was probably a meteor. The case file notes that the observation was a visual surface observation without electronic or optical equipment. The observer's reliability was listed as unknown, though records indicate he was employed at a local Air Force base. No physical evidence of the sighting was recovered, no interception or identification action was taken, and the location of any aircraft in the area at the time remains unknown.

The file includes 31 pages on microfilm as held by the National Archives.
