I think Tom is referring to the specific construction methodology for 
the WTC which IIRC had a single solid spine up the middle.  From memory 
the documentary I saw said that the burning jet fuel simply melted that 
spine enough the the floors simply fell inward.

I'm not an engineer so I'm not about to go into the feasibility of 
that.  All I will say is that it sounds a lot more feasible than a 
building with a shedload of steel crossbeams on every floor which would 
require the careful placement you mentioned.  Also older buildings were 
not always built to the symmetrical designs of today so the chance are 
if you blow one of *them* up it will fall to one side.  If however you 
place an explosive at the central weak point of a symmetrical building, 
chances are the equal weight upon it from every direction will cause it 
to fall inward.

Again though I'm not an engineer, that just seems logical.

Kind regards,

Julian
