Rectangular UFO sighted in San Antonio in 1959

Summary

In April 1959, a witness in San Antonio, Texas, described a rectangular object with a slightly pointed front and a long, slender tail. The object, the size of an orange, glowed with a color similar to a bright yellow flame. It was observed for 15 minutes from a car, moving from north to south, descending, and then disappearing behind trees. Despite its unusual appearance, investigators considered it could be an aircraft with fluorescent markings or a commercial spotlight illuminating clouds. The area was known for heavy air traffic and the use of advertising lights.

The object's description didn't match any known aircraft, which generated some curiosity. However, weather reports and the location of the sighting led officers to dismiss an extraterrestrial explanation. The lack of sound and the object's unusual trajectory added mystery to the case, although it was eventually filed as likely a terrestrial phenomenon. This document is an example of how UFO reports were rigorously analyzed during the Cold War.
