Project 10073 Record Card and UFO Report — San Antonio, Texas, 5 August 1963

On August 5, 1963, at 1655Z, a civilian observer in San Antonio, Texas, reported sighting an unidentified object. The observer, a farmer, described the object as round and pin-head sized at arm's length, exhibiting a color change from white to blue to red. The object was first observed at a 90-degree elevation above the northern horizon and was seen for approximately 15 minutes before disappearing at a 60-degree elevation above the western horizon. The observer used binoculars but could not distinguish any specific details or characteristics of the object. The 741 AC&W Squadron was contacted but reported no radar contact of the object. Meteorological data for the time indicated clear weather with visibility of 10 miles. The official conclusion reached by the Air Force, as documented by Major James A. Quillin, was that the object was likely a balloon. This assessment was based on the object's movement, which was described as drifting with the wind, and the fact that balloons were known to be launched from locations to the southeast of San Antonio, such as Corpus Christi, or potentially from local sites.
