Having grown up living on military bases, I would have guessed a sonic boom. But if the military says no........weird. We had a huge boom here when the Box Factory blew up 2 blocks from my house in the middle of the nite. Unbelievably loud and the house shook like an earthquake was happening. My dtr's room was glowing orange from the fire (her window faced the flames). We couldn't get within a block of it because of the heat. But, back to the boom, I hope someone figures out what it was. UFO, maybe
