Unconventional Aircraft Sighting - Biloxi, Mississippi, 18 November 1949

This report details an investigation conducted by the 9th OSI District into an unconventional aircraft sighting that occurred on 18 November 1949 in Biloxi, Mississippi. The sighting was reported by personnel at the Biloxi Veterans Hospital, including the Chief Guard and other staff members. According to the report, the object was first sighted at approximately 1000 hours, positioned south of the hospital near Ship Island. The witnesses described the object as a single, white, cigar-shaped craft, estimated to be 200 feet in length. It maintained a steady, horizontal flight path from west to east at an altitude estimated between 2500 and 3000 feet, with a speed of approximately 50 miles per hour. The observers noted that the object reflected sunlight but lacked any visible wings, control surfaces, exhaust, or engine noise. The object remained in view for approximately 25 minutes before disappearing behind a tree line. The Executive Officer of the Veterans Hospital, Mr. Elsworth J. Sacks, was interviewed regarding the reliability of the witnesses and confirmed that they were trained to observe and report unusual incidents and were considered entirely reliable. The investigation included a review of local weather conditions at the Keesler AFB Weather Station, which confirmed clear visibility at the time of the sighting. The report concludes that the method of propulsion and control could not be determined, and the 9th OSI District stated that no further investigation of the case was contemplated. The document includes the completed 'Essential Elements of Information' form for Project SIGN, which provides a structured breakdown of the sighting characteristics, including the lack of radar contact and the absence of any known aircraft in the vicinity at the time.
