Project Blue Book Sighting Report — San Angelo, Texas, 23 September 1966

This document contains the official Project Blue Book records regarding an unidentified aerial phenomenon reported on September 23, 1966, near San Angelo, Texas. The primary witness, a 24-year-old civilian housewife, reported observing a single, round, red object for approximately 20 minutes. According to the witness, the object exhibited a pendulum-like motion, moving back and forth unevenly in a north-to-south direction. The witness described the object as having a 'buzzing' sound and noted that it faded out twice before returning. The witness estimated the object's size to be roughly ten times that of a house and positioned at an elevation of approximately two miles. The report includes a formal letter from Major Hector Quintanilla, Jr., Chief of Project Blue Book, dated September 30, 1966, informing the witness that the information provided was insufficient for a formal evaluation and requesting the completion of a more detailed questionnaire (FTD Form 164). The military's internal assessment, documented in a staff message from the 6940th Security Wing at Goodfellow AFB, confirms that there were no known aircraft in the area at the time and no weather balloons released by local activities. Despite the witness's reliability and the detailed nature of the questionnaire responses, the official conclusion remained that there was insufficient data to identify the object.
