it's pretty silly at this point to think the jet fuel would get the job done.
It'd be one thing it everything from the top down to the aircraft hole collapsed and tipped over onto the streets below. That I can believe. But to have 80 floors of an extraordinarily built set of buildings to just say, "Fuck It" and give way is completely ridiculous.
IMO the only reason people don't want to consider explosives being in those 3 buildings is because that opens the door to some very unpleasant possibilities.
