Dazed: Okay great, this is what I wanted to hear. You're saying that floors were collapsing prior to global catastrophic failure.
So, on the one hand, the tower collapsed so quickly, because when a floor fails, all the top floors crashing down could not be resisted by the lower structure, yet when it comes to accounting for explosions, we have all sorts of floors collapsing independently of the rest of the structure, without triggering catastrophic failure. Is this a reasonable summation of your argument?
