That's a good question.  I don't know the answer.

Baically, no, I don't claim to have the expertise.  If you have an
hour to spare you could listen to the podcast on the Popular
Mechanics site and see what you think.

I will say one thing that I gathered from that site.  It seems the
World Trade (WT) towers were of a unique construction, unlike
other Manhattan skyscrapers.  They were build around a central
core, with tubular steel supports on the outside of the building,
and with 60-foot unsupported steel beams connecting these two
structural elements.  Most skyscrapers have more of a steel grid
structure, and more dispersed columns.

The WT design choice was explained partly in architectural terms
(the need to minimize weight per floor, given the unusual height
of these things) and partly on financial grounds (the desire to
maximize rentable square footage per floor, and hence not to have
columns protruding through the floors other than at the core).

I gather -- though, once again, I can't claim to confirm this --
that this structural pattern helps explain the rapid catastrophic
collapse.  I also gather that some experts, on first seeing video
of the collapse, thought it "looked like" controlled demolition,
but on learning about the structures did _not_ claim that it
actually was such.  Finally, I gather that various conspiracy
sites cited these experts' first impressions without adding their
subsequent disclaimers.
