Battle of Los Angeles
U.S. Army anti-aircraft batteries fired more than 1,400 shells at unidentified objects over Los Angeles in the early hours of February 25, 1942, two months after the Pearl Harbor attack. A widely-circulated Los Angeles Times photograph appeared to show a large object illuminated by searchlights.

Office of Air Force History 1983 report ↗Official description
The U.S. Army's official 1983 investigation by the Office of Air Force History concluded the event was triggered by a meteorological balloon, with subsequent gunfire compounded by 'war nerves' in the aftermath of Pearl Harbor. Six civilians died (three in shrapnel-related incidents, three from heart attacks).
Editor's context
Often cited in popular UAP discourse, but the historical record is well-documented. The newspaper photograph that appears to show a craft is now generally understood as searchlight beams converging on smoke and shrapnel clouds. The case remains historically significant as an early example of mass anti-aircraft response to an unidentified target.
Prevailing explanation
What scientists and analysts generally think
The Office of Air Force History's 1983 review concluded the precipitating event was a meteorological balloon, after which jittery anti-aircraft units fired at perceived targets including their own shell bursts. The famous photograph shows searchlight beams converging on smoke and debris, not a structured craft. This remains the standard historical interpretation.
