On the night of 23 July 1952, at approximately 2105 hours, three prison guards observed a round, flat, greenish object at an altitude of 50 to 100 feet. The object was described as moving slowly toward the south before suddenly accelerating and ascending vertically.

The report confirms that the observers were interviewed by a special agent and that no physical evidence was obtained. The weather was described as a clear night with good visibility and a light wind from the south. The document includes a completed observer questionnaire, which provides additional details about the witnesses' experiences, including their professional backgrounds as prison guards and their certainty regarding the sighting. The report concludes that there was no known activity or condition, meteorological or otherwise, that could account for the sighting. No interception or identification action was taken by military authorities, and the case was forwarded to the Air Technical Intelligence Center at Wright-Patterson Air Force Base for further review.
