Blackwolfe, that's why Remington made their military ammo plant in Bridgeport CT in the shape of many 'H's' joined in the middle. Like HHHHHHHH except for the spaces between the letters. In the event of an explosion, only one section would be destroyed. Plant eventually sold to GE and converted to office spaces. Now demolished, the land is being converted to a school. In that part of Bridgeport, it will be destroyed soon.
