I have my doubts that we got it all... I think that BushCo held things back to hide their own incompetence in not stopping it...

I also have HUGE doubts about what REALLY caused the two buildings to collapse the way they did.  It was too close to a controlled demolition... I'm NOT accusing the government of doing it, but those buildings fell almost on cue like "pulled demolitions".  HOW did that happen? 

Any structural engineers lurking or members ?
