Neosho, MissouriSeptember 1954

On September 21, 1954, at approximately 5:34 p.m., a driver traveling between Carthage, Missouri and Fayetteville, Arkansas observed an unidentified flying object near Neosho, Missouri. The witness was alone in his vehicle and had professional training in timekeeping, making him confident in his ability to track the sighting's 24-second duration. The object appeared as a saucer shape roughly 25 to 30 feet in diameter, positioned between 10,000 and 12,000 feet above the ground.

The object displayed unusual movement throughout the observation. It initially moved at a leisurely pace while rolling slightly from side to side. During the first part of the sighting, the witness noticed four quadrature markings (features arranged at right angles) on the visible surface of the craft, though he could not determine whether these were raised projections, indentations, or simply color variations. Around the 11-second mark, the object executed a sharp loop and appeared to present its edge to the observer. At this point, its apparent size seemed to shrink to about one-third of its original size. The witness caught a brief glimpse of what he described as a projection on the top surface resembling the conning tower of a submarine. The object then accelerated rapidly, performed a second loop around 14 seconds into the sighting, and disappeared from view by 24 seconds. No sound, smoke, or vapor was observed, though traffic noise in the area prevented the witness from ruling out sound entirely.

The witness offered three conclusions in his written report: first, that occupants of the craft had detected observation and ascended beyond visibility, possibly alerted by radar or other detection methods operating in the area near Camp Crowder. Second, he speculated the object employed an unknown form of propulsion, possibly atomic, based on its sudden acceleration and extreme speed. Third, he noted the object's tight loops were too abrupt for an air-supported craft, suggesting it did not rely on air for either lift or guidance.

The U.S. Air Force Office of Special Investigations received this report in May 1955, eight months after the sighting occurred. The Air Force's evaluation was marked as "insufficient data for evaluation" because investigators deemed a proper assessment impossible without conducting a follow-up interview with the witness.
