Back in 1942, just months after Pearl Harbor, LA had one of the weirdest nights in history—the Great Air Raid. Sirens wailed, searchlights lit the sky, and anti-aircraft guns fired over 1,400 rounds at… something. Witnesses reported planes, flashing lights, even a giant UFO, but no wreckage or enemy was ever found. The government blamed it on nerves and maybe a weather balloon, but conspiracies about aliens, cover-ups, and secret missions have kept the mystery alive ever since.
