To demolish a building of that size doesnt require weakening throughout the structure for it all to fall at free fall speed.

Would weakening just the top third and guiding the planes to the right spot at the right angle eventually do enough damage to generate an falling impact of a magnitude that the lower part of the structure was not designed to withstand?
