June 21, 1950 — Hamilton AFB, CA  
1:35 a.m. Control tower operators Cpl. Roger G. Pryor and S/Sgt. Ellis R. Lorimer and airways communications staffer S/Sgt. Virgil Cappuro watch a flying disc speeding at 1,000–1,500 mph over Hamilton AFB [now closed] in Novato, California. The object shoots blue flame and makes a roar like thunder as it makes five passes over the base. They observe it through binoculars for 25 minutes. [Eberhart]
