Was the Battle of Los Angeles Caused by a FU-Go Balloon Bomb?

The story at the time was that war nerves, lack of training, and hysteria caused people to begin firing at an object in the sky. UFO researchers have suggested that instead the trained individuals did exactly as their training dictated and there was something strange in the skies over Los Angeles.

Since then, suggestions have been made that the event was sparked by the appearance of a Japanese FU-GO balloon bomb that night. It was crucial that the event - a foreign powers weapon actually reaching the continental United States - be covered  up. A similar event occurred in the Pacific Northwest and a several members of a family were killed when they touched something they happened upon on a picnic in the woods. That action triggered the bomb.

On February 25, 1945 citizens in Bigelow, Marshall County, Kansas found a FU-GO balloon bomb. That community is located in NE Kansas south of the Nebraska line but also close to significant military bases in the SE corner of Nebraska (Omaha)  and NW Missouri (Kansas City).
