April 3, 1952 — Benson, AZ
8:23 a.m. Three civilian Air Force pilot instructors, Chauncey P. “Chick” Logan, C. M. Jasper, and Paul Wilkerson, and several others observe a bright-silver oval object above the airport in Benson, Arizona. Hovering at 55,000 feet, the object is in view for nearly an hour, during which time it stays in the same position in the sky. Logan flies a T-6 trainer aircraft up to 13,500 feet to better observe the object, but there is no change in apparent size. [Eberhart]
