My understanding of how the buildings came down has actually been influenced by Jeffrey's ROOSD explanation. Relatively quiet thermite charges and well placed explosives high up the building triggered the progressive collapse. But remember there were witnesses (many) who claimed to hear these explosives.
Why weren't these charges picked up on they many mics. From what I understand from both Tony and Jeffrey, WTC 1 & 2 were easier to bring down. All you needed was a mass of material reaching sufficient velocity to hit the lower floors and you Bobs your Uncle. WTC 7 really did require the blowing of massive beams; a ROOSD collapse would not have been possible.
I know Jeffrey thinks he can pin it down to the one beam that started it all that would trigger the nice, neat symmetrical collapse. Come on. That dog won't hunt.
Lauren,
I think 7 was not the destruction of one steel member down at the mech floors. These member were massive and not going to weaken from heat... perhaps maybe cutting torches but the were very thick.. I would guess it would be a big job and many hours.
However... those massive steel sections were joined with gussten plates and bolts and some welds in places. Those connection plates WERE vulnerable to heat or cutters and even devices. But once a truss fails... like a truss bridge which loses one connection or chord... the whole thing completely collapse. You betcha! One of those trusses collapse will cause the structure to twist and it will pull other members attached to it and the failure will race though the mech floors and everything these massive structures supported will drop like a lead sinker. leaving the perimeter columns holding onto the curtain wall and nothing to support them.
Yes 7 could be a relatively small attack of a few connecting plates and then it's all she wrote.
