July 27, 1952 — Manhattan Beach, CA  
6:35 p.m. A group of eight pilots and engineers see a large, silvery object moving rapidly at a high altitude over Manhattan Beach, California. After it makes a turn, the UFO separates into 7 discs that form into groups, circle, and speed out of sight. Former Navy pilot and aircraft engineer J. E. Kempf says the formation looks like a “stack of coins.” [Eberhart]
