OMG this is what troughers fear, they will jump up and down and scream and call names and hide under their beds looking for a mushroom cloud that will never appear. So we start out with a tower, its starting to come down, watch the roofline.... Not even building 7 completely disintegrated in midair! Then there is the problem columns turning to matches! Maybe fang was right and fractured steel would be pyrophoric huh... Of course the question is how did it get that way? columns disintegrat9ing mid air and how many times doe Wile E Coyote have to be told not to ride the steel rockets he would have won the race to the ground though I just can imagine what could do such a thing, maybe someone here can help us investigate this strange event? What up here troughers what kind of weapon can do these things?? POOF DUST!
