What theory do you want to hear, the one that it was clearly demolished?

Any structural engineer who has any respect for himself/herself and knows anything about structures and how they fall will without a doubt confirm that.

It's so obvious it's painful.

I won't bother typing up 10 pages to tell you...the information is all out there. Just do some research...and try and find legitimate sites and credible people. There are, admittedly, alot of crackpot explanations of what happened that day...but one explanation that is painfully obvious engineering and physics-wise is that those buildings were systematically brought down.

It's not the first time a government has conducted a false flag operation and it won't be the last.
