“Firing, first heard at 3 a.m., ceased suddenly at 3:30 a.m., after the object disappeared south of Signal Hill, at the east edge of Long Beach. Anti-aircraft guns fired steadily for two minute periods, were silent for about 45 seconds, and continued that routine for nearly a half an hour.” This 30 minute barrage of anti-aircraft fire from the United States military could not take down the object.
