How did Building 7 fall?
I don’t know. I am not a structural engineer, but the theory that Bush or some shadowy figure pressed a button to demolish that building is one of the most asinine theories imaginable, but I have read it here multiple times. I have some higher education in demolition, and there are multiple examples of unexpected damage to collateral structures for numerous reasons. Consider that blasters routinely use seismographs to monitor shock waves in the ground and damage to nearby foundations is the reason.
Given the sheer weight that impacted structural concrete when both towers fell on the foundation and open spaces underneath for the transit tunnels it does not seem as outlandish to me as it does to many. The skeletal structures of high rise buildings are often attached to the ground and foundation at far fewer points than one would think. They derive their strength from being in a line (same theory with a newspaper if it is rolled up - surprisingly strong end to end). In fact, the common method for explosives demolition uses far less explosives than one would imagine because the goal is to cut those supports with as little explosives as necessary and gravity and sheer mass does the rest of the work for you to take a structure down.
The lack of understanding of these basic principles that I have seen on the conspiracy sites should be embarrassing for the writer in my humble opinion.
It was knocked over by a stiff wind. ;)
Here's a pretty good write-up on it: WTC7 Damage
