Stacked and dried cow poop explodes. Don’t think anyone snuck in 5k lbs of anfo.
In GE we were told of a GE town that blew up/disappeared following a literal mountain of dried cow poop detonating. It was just after WWI. The owner was told he had to get rid of the cow poop mountain. It was so hardened he decided to use dynamite to break it up. Or that’s what he supposedly told the mining store clerk cause everyone in that town got blown up. Don’t know if it’s true or not but that’s what we were told.
The rafters of the yuge building might have been built up with years of dry dusty Texas cow poop. Major SNAFU causes ignition. Not quite an explosion but it went up in a flash. Dust explodes with low humidity and the right conditions also.
It goes into the sewage lagoons in the background then it is spread as liquid fertilizer on the fields of crops that feed the cows. There are no manure piles on this facility.
