Guy. Building 7 is the first and only steel frame building in history to supposedly fail due to fire.
It looks like you found a new way to perfectly implode buildings. Just blow a one steel girder on floor 13.
Maybe you can patent it or something.
But seriously, read this report by actually competent engineers and not idiot propagandists in Popular Mechanics

Interesting; thanks.
Yet, the building integrity failed.
