It was suspicious that it came down so fast......how do you explain it?
uh, gravity?
As for the speed with which the building collapsed, look into something called "failure of redundancy". Once a building reaches its failure point, a chain reaction ensues and the whole thing comes down within seconds.
I can very highly recommend this book:
You'll find that most major structural failures happen in a big hurry. The warning signs are subtle; the actual collapse is sudden (I used to work in construction law, and did a lot of litigation involving construction failures of various kinds. Bought this book on the recommendation of a colleague.)
Easy to explain it. You've filled your noodle with a bunch of mush about PNAC, NWO, Trilateral Commission, Bildeberger, Illuminati. *list conspiracy here*, and you'll happily gargle it.
Could you please summarize your architectural and/or civil engineering credentials, and give a detailed explanation of why it's suspicious. Said explanation should not refer to your own erroneous claims that have been corrected.
Please note that you have opened this particular line of conversation on 9/11 more than once, you have been corrected more than once, but you continue to persistently post the same nonfactual allegations over and over again.
I think it's time you laid your cards on the table. What, specifically, is your agenda?
