UFO Sighting Report — Mansfield Dam, Texas, 24 June 1967

On 24 June 1967, at approximately 0312 hours CDST, a civilian witness observed an unidentified aerial object near the Mansfield Dam, approximately 20 miles northwest of Austin, Texas. The witness, a student at the University of Texas with a background in rocketry, was in a parking lot with his St. Bernard dog when he noticed a blue, cigar-shaped object traveling in an arc from the northwest to the northeast. The object appeared solid and displayed high velocity. The witness attempted to signal the object using a 6-volt spotlight, flashing it ten times. In response, the object reportedly stopped and increased its brightness threefold for approximately 75 seconds before continuing its flight path. Later, the object slowed and dimmed its lights when the witness signaled again. The witness observed the object through 6x binoculars, confirming its elliptical shape and noting that its longitudinal axis was tilted relative to its path of travel. The witness also reported a feeling of being watched, which he compared to mental telepathy, though he noted he received no direct communication. The incident was reported to Bergstrom Air Force Base approximately nine hours later. The witness expressed frustration with the Air Force's initial assessment that the information provided was insufficient for scientific evaluation, arguing that his detailed report and diagrams were significant. The case was subsequently forwarded to the University of Colorado for further study.
