Actually - do they even build skyscrapers that high without planning up-front what they would do to eventually take them down if they had to?
Also, from the films of the WTC tower collapse, it looks like they collapse initially at the points where the planes went in. The 2nd tower collapses first because the bastard probably knew more weight and stress would be on the damaged area if it was hit lower on the building.
But realistically - could a building like that withstand the falling weight of the upper levels (mass times acceleration) - or would it split apart like a flat weight applied to an upright straw?
