1954-11-15 — 21 miles SSE of Baboquivari Park, Arizona

On 15 November 1954, a civilian on a biological field expedition 21 miles SSE of Baboquivari Park, Arizona observed a brilliant silver round object with an orange glow, beachball-sized at arm's length. The object appeared to rise from a sandy dune at a 100-degree angle, performed almost a perfect right-angle turn at approximately 600 feet, and disappeared NNE at approximately 1,000 mph. Estimated speed 600-700 mph initially. Two exhausts came from the bottom and additional exhausts from two cannon-like objects on top. Sound resembled a large vacuum cleaner. The observer had a Polaroid Land Camera and obtained one photograph. Total observation was 3-3.5 minutes. 2nd Lt. Dewey L. Nigle, 169 AC&W Squadron Phoenix AZ, prepared the report 19 November 1954.
