Structural failure due to catastrophic damage and fire? Sorry, but thats not "unproven" nor is it unlikely.

Thats the North face of the building - side away from where debris
impact from WTC 1 ripped away most of the building
Maybe should watch this
www.911myths.com...
Can see smoke pouring from most floors on south face.

North face of WTC 7 was black granite
South face was red granite

meaning????
the facade is a NON-SUPPORTING structure...it is a cosmetic application, so, WHAT'S YOUR point?

Verison (140 West) - large masonary building can be seen to left in some shots. [...etc]
As for WTC 7 collapsed and WTC 6 didn't - becuse of differences in
construction
NIST determined that diesel fuel did not play an important role, nor did the structural damage from the collapse of the twin towers. But the lack of water to fight the fire was an important factor. The fires burned out of control during the afternoon, including on floor 13, where a critical interior column buckled. With the buckling of that column, adjacent columns also failed along with the floor structure above. This triggered a vertical progression of floor failures to the roof. The collapse then progressed east-to-west across the structure, and ultimately the entire structure collapsed. The fires, fueled by office contents, along with the lack of water, were the key reasons for the collapse.[45]

Now thats the problem. Either truthers fixate on fire OR the fixate on the damage. They forget that it was both that caused the buildings to fall. Then they rely on the educated guess of the NIST report for the arrows they try to sling at the reality of the situation.
The building was equipped with a sprinkler system, but had many single-point vulnerabilities for failure: the sprinkler system required manual initiation of the electrical fire pumps, rather than being a fully automatic system; the floor-level controls had a single connection to the sprinkler water riser; and the sprinkler system required some power for the fire pump to deliver water. Also, water pressure was low, with little or no water to feed sprinklers.[
After the North Tower collapsed, some firefighters entered 7 World Trade Center to search the building. They attempted to extinguish small pockets of fire, but low water pressure hindered their efforts.
-- from inside the building at the 8th or 9th Floor elevator lobby, where two elevator cars were ejected from their shafts and landed in the hallway north of the elevator shaft, the visible portion of the south wall was gone with more light visible from the west side possibly indicating damage extending to the west.

I have always said it was a combination of damage and the fires that doomed all three buildings that day.
