The 'pancake' theory seems believable to me. Once a single floor failed and tons of concrete pancaked down upon the floor below, it set off an unstoppable avalanche.
So the buildings, in essence, swallowed themselves?
Floors falling inside ontop of each other created a momentum in bringing everything down?
That does make sense to me.
Ah...don't be too hard on this nut case...it's not easy getting over having been abducted by aliens and "probed"...it drove this guy nuts, and It's driven others nuts too...just visit DU.
Floors can't collapse inside the outer building structure because it's all one and the same!! Each floor of a high rise building is essentually all one piece supported by pilars, stack one on top of the other. Some pillars are lessor supporting pillars that don't run through several levels, others are main supports which run through several levels to which the slab is attached to.
Even if you postulate the existence of explosives, I don't think al Qaeda managed to hide explosives in each and every floor of the WTC, nor could they sequence the explosions to make it appear that the buildings fell down from their own weight. Whatever happened to start the failure, it continued on its own due to...gravity.
The outside of the building is merely sheets of glass that are hung and supported between each of these slabs.
Sorry, I don't understand anything about construction to follow what you said. The floors did come down into the lobby though.
The better tequilas aren't nearly as halucinogenic.
In the case of the WTC, the outside of the building was the main support structure. Holding up those panes of glass were steel beams. It was like an exoskeleton. Once the planes ripped gaping holes in that exoskeleton and then smashed and melted many of the interior columns, anything could happen.
Some buildings are constructed such that every 10-12' of exterior wall is supported by the floor below which is in turn supported by the wall below that, etc. The WTC was not constructed in such fashion. The walls themselves were pretty solid, and the floor trusses were fastened to them. The wall columns did rely upon the floor trusses to provide lateral stability, but the gravitational loads of the wall columns did not rest upon the floor trusses. Indeed, for a building of that height, putting the weight of the upper floors on the lower floors would have been absurd.
Air gets compressed as this happens, which blew out windows, making it look like little explosions just before the floors above pancaked into the next one below, and so on.
Many, if not most, buildings will suffer severe structural damage from the loss of even one major support pillar. That the WTC did not collapse immediately from the loss of many consecutive supports is pretty remarkable.
You make me puke.

Now that understood! THIS is why explosions were heard before the buildings collasped??!!
Of course this professor probably also believes that Joseph Smith translated long lost revelations from an ancient prophet using a peep stone while peering into a hat.
I'll take this "scientist" for what he's worth.
The wtc main support was provided by the central shaft, which in essence was a giant sized pillar (Like a tree trunk, but a little more complicated than that). Each slab also had "walls" which ran all the way to the exterior (in a cross shape from the center like you say. The pillars gave support and stability in between those for the floor above.
I think we are on the same page essentually. There is a blueprint around somewhere which shows how the towers were built.

There were explosions. Here is coverage of the 911 calls.

Forte Runningrock at post 111 seems to have a good explanation about that though.
Why, indeed, would terrorists perfectly drop buildings into a pile when it's much easier (and more plausible) to knock out one corner and hope they would fall across several blocks, doing ten times the damage?
Either you have a tinfoil conspiracy theory, or you accept the obvious...the buildings just fell down due to gravity.
