Nice big pictures here:

We see the steel core standing at LEAST 50 stories, then as we know it collapses into pieces afterwards.

Smaoke and some damage from building 7 is seen, and importantly the fact (visually) that the black smoke (if attributed only to 7) is evidence of a cold fire, not a hot one.

The damage is not thoughrough and clearly does not go through 9 sections in. Look closely at the damage below, there should have been HUGE pieces of STEEL reinforced concrete 40 stories high and 9 windows deep, considering the colums placements etc AND the fact that the OTHER side of the building was also intact. So, unless you had rigged it with hight explosives to demolish or "Pull it" as Lease ownwer Silverstien admitted...it would NEVER have collapsed.

Nope, it should not have collapsed, and certainly not in the manner that it did.
