RANDOLPH AFB TEN, [ILLEGIBLE]Date unknown

On the afternoon of July 21, 1952, a woman in Converse, Texas spotted an unusual aircraft near Randolph Air Force Base. The object was elongated with a pointed nose, no wings, and a protruding box-like tail section. It appeared silver-colored and moved faster than the B-29 bombers (airspeed around 150 miles per hour) that were in the landing pattern at the base about 4 miles away. The sighting lasted between 3 and 5 seconds.

The object flew level from northwest to southeast on a heading of approximately 140 degrees, matching the direction of the B-29s approaching the runway. Then it made an abrupt turn upward and climbed vertically out of sight. The woman was standing in front of her home at 1630 (4:30 p.m.) when she observed the object at low altitude, slightly above the landing aircraft. She had spent years around military and civilian airfields and stated the object resembled nothing she had seen before.

The investigating officers noted that the woman's husband, an Air Force captain, had witnessed a similar sighting a week earlier on July 14 while flying in a B-29 at 1500 feet altitude. He described the same type of object making the same maneuver, climbing vertically out of sight at speeds exceeding 1100 miles per hour. Both sightings occurred near Randolph AFB, and the captain confirmed his wife's account. Weather conditions at the time were scattered clouds, 15-mile visibility, and winds aloft at 21 knots from 150 degrees. Meteorologists determined no atmospheric phenomena could explain either sighting. No photographs or physical evidence were recovered, and no interception or identification action was taken.
