Battle of Los Angeles
The February 1942 anti-aircraft barrage over Los Angeles, where over 1,400 shells were fired at unidentified objects just months after Pearl Harbor.
INVESTIGATION OVERVIEW
In the early morning of February 25, 1942, less than three months after the attack on Pearl Harbor, unidentified objects were detected over Los Angeles. Anti-aircraft batteries opened fire, and over 1,400 shells were expended over approximately 45 minutes. The objects, illuminated by searchlights, moved slowly across the sky despite heavy artillery fire. The Los Angeles Times published a famous photograph showing searchlights converging on an object. Secretary of War Henry Stimson called it a 'false alarm,' but no enemy aircraft were ever found and no bombs were dropped. The incident remains officially unexplained.
KEY CLAIMS
The objects withstood anti-aircraft fire without being hit or affected
Radar confirmed multiple targets over Los Angeles that night
The military response was triggered by genuine unidentified objects, not hysteria
The official 'false alarm' explanation was a cover story
The incident influenced later government UFO secrecy policies
SUPPORTING EVIDENCE
Los Angeles Times photograph shows searchlights converging on an illuminated object
Western Defense Command after-action reports document the scale of the response
Radar operators reported multiple targets, not a single object
Over 1,400 anti-aircraft shells were expended with no wreckage recovered
Congressional inquiry documented contradictory official statements
COUNTER ARGUMENTS
War nerves were extreme after Pearl Harbor, making false alarms likely
Weather balloons or a lost commercial aircraft could have triggered the response
The photograph is ambiguous and could show searchlights reflecting on clouds
Secretary Stimson's investigation concluded it was a false alarm
No physical evidence of the objects was ever found
