Building 7 is no different than the Marriott Hotel that was demolished by debris falling from the Twin Towers.
All the fire fighters and water went to trying to save the Twin Towers. They did not have enough water and manpower to save the buildings around them.
There is only so much water pressure available in southern Manhattan.
The Building 7 issue is this—are there any other buildings ever, anywhere in the world, that fell in their own footprint due to debris from neighboring buildings?
I believe the answer is “no”—but I can be persuaded with a counter-example.
