Someone is going to be taking a serious look at the structural integrity of these buildings, especially since the structural engineer who designed them insisted at a recent conference that they were designed to handle a crash from a large passenger jet.

They both survived the crash. They probably did not analyze for the jet fuel fire!

Yes. Over the last day and a half I've been reviewing tons of information along these lines, and it is clear to me that the buildings did very well. They were also designed to collapse upon themselves (instead of toppling sideways) in the event of a catastrophe.

The reason I posted that speculation yesterday was that I was aware that the design of the structures was considered innovative at the time and hadn't been used before on a structure as large as the WTC.
