Nah, that has to be WTC6 on the left.
WTC6 is hard to find information on, but that hole would definitely be placed low on WTC7 (~3rd floor, upwards an unknown amount of floors, about 8 or
9 floors can be assumed to be damaged at least somwhat, imo). Hard to see its height from the smoke, and hard to make out a general width for
If you follow the high, upper-left corner of WTC7 down, you can get a general idea of where that corner of the building was. If you look about "Steve
Spak", you'll see a patch of sky, signifying that WTC7 no longer extended laterally there. It also seems like you can make out a clear vertical edge
on the left side of that patch of sky.
Based on the above, we may be able to get an idea of where exactly this hole would be on the face. It looks to me to be a little more towards one side
of the face than centered near the middle. This is hard to judge too, but at least we may be able to get some
idea from the photo.
So there appears to have been a gash low on the back face of the building, closer to the Verizon Building, of at least 8 or 9 floors with at least
some damage, and indeterminate width.
If we had a better photo we'd be able to establish a lot more, I think. But maybe someone else can get more
info out of the above.
Let's put this in perspective, too.
That's the Bankers Trust Building. Damaged by the WTC Tower collapses.
WTC5 was not a skyscraper. It had much thinner
columns than WTC7, and was no doubt less over-engineered. It was constructed with similar
materials. It was severely damaged by both debris and
fire and yet only suffered very localized collapses. WTC5 had to be demolished in the
What still needs to be established, as NIST is attempting, is how scattered patches of fire and a localized gash lead to this:
Obviously, fire and debris damage does not
automatically lead to free-fall global (or even extensive local) collapse, as WTC5 shows. How
other than controlled demolition could lead a building to free-fall
global collapse, under its own weight, is beyond
Massive steel columns, concrete, etc., provide resistance to falling objects. That is just irreconcilable fact. Resistance will be provided. Free fall
can only be achieved when resistance is prevented.
