<<< the pancake theory works if you demolish sections of the core ahead of the collapse progression. >>>

Or, instead of demolishing sections of the core with explosives planted seceretively by federal agents (difficult to believe), maybe people should consider what actually took place; as the floors failed, the lateral bracing of the central columns was removed and they buckled.

As you watch the buildings fall in the videos, you can't really see the floor slabs failing and the core columns buckling. You see the perimeter columns buckle and fail, but that is lagging what is taking place on the interior of the building.

1. The floors fail in a particular area
2. This creates an unbraced core column area and these columns buckle.
3. The entire central core of the building falls
4. The exterior columns lag slightly behind the interior collapse, and buckle and fail slightly behind, but in succession with the interior collapse.

This collapse sequence seems very logical to me. Apparently some don't see it that way so they choose to believe far-fetched theories that have much larger holes in them. That's not a reflection on the collapse sequence of the building, but on the character of the people that choose to ignore the obviously logical choice.
