Response to Brought to mind...

Of what I would expect to have seen on the north tower ... ((IF)) it truly fell ...



The problem is that the towers were steel column structures and they both STOOD after being struck by planes. So then you have FIRE "softening" the metal and it "gives" like taffy slowly pulling.

Well right there, you DON'T have any impact! You have a gradual sagging until the top meets the bottom ... with likely some torsion offset. The top weighs no more than it did originally and originally, the bottom section had plenty of strength to support the weight of the top.

Even if floors fell out some, the outer structure should have hung itself up there on the outer perimeter columns -(which were all tied by spandrels around the entire "circumference" of the building)- and ... the formidable core structrure.

So, in the videos you see what happens to a building when it BEGINS to free fall and then gets stopped suddenly ... exactly what should have occurred with the towers collapsing.
