Found this on Wiki today never knew however this happened..does anyone else have any data on this.? West Coast Air Raid In the "West Coast Air Raid" of early 1943, a UFO was spotted over Los Angeles. Over 1400 rounds of AAA (Anti Aircraft Artillery) were expended and several people died from heart attacks due to the excitement. It was written off by the government as "wartime nerves" as a Japanese Sub was sighted off the coast days earlier., but later documents indicated the U.S. military was seriously worried about the incident. !
