I dont really undestand why building 7 is such a big deal. Nobody died because Building 7 collapsed, so who cares? if Bloomberg wanted to demolish his own building then good for him. It still doesn't erase this:
You can see the jet emerging from the other side of the building. It sliced all the way through. And that fireball is like 40 stories in height.
40 story explosion plus a subsequent 20 story gaping hole and fire. Thats how 3000 people died.
