PROJECT 10073 RECORD CARD — UFO Sighting, Walker AFB, New Mexico, 21 June 1958

On June 21, 1958, at 0940Z, A/2C Kenneth R. Polley of the 630th AC&W Squadron at Walker AFB, New Mexico, observed two unidentified objects in the sky. The witness described the objects as circular, pale gold, and approximately the size of a dime held at arm's length. The objects were traveling in a trail formation at a high altitude, estimated at 40,000 feet, and moved at a high rate of speed from the West to the East. The observation lasted for approximately 25 seconds, during which time the objects made no sound and left no tail or contrails. The objects eventually faded in the East and did not appear to fall. The weather conditions at the time were reported as clear with some clouds. The control tower at Walker AFB did not observe the objects, and no other sightings were reported in the area. An ATIC evaluation concluded that the objects were likely balloons caught in a high-altitude jet stream, citing wind directions and speeds as the primary evidence for this determination, although the initial report noted that there was insufficient data for a final evaluation.
