Larry, your article certainly warrants a thorough response, and it will have one. I'll need a little bit of time to write it.
In the meantime, let me just point out that, for obvious reasons, there are plenty of loony conspiracies about the attacks (some people saying there were no planes involved, etc.)
But if you cast aside of all them, you are still left with no easy explanation as to how the terrorists could have taken control of the planes and guided them to their targets, a process which took a good while, without any response from the various Air Force, Army, and FAA rapid-response teams.
No explanation, either, for why the FBI and CIA were ordered off of Bin Laden's trail as they discovered evidence of the impending plot.
No explanation for why the Secret Service didn't evacuate Bush from Booker Elementary school, when they could not have safely assumed Bush would not have been a target (his appearance was announced in the Sarasota Herald-Tribune three days prior).
No explanation for why Larry Silverstein, owner of the WTC complex, gave the order to "pull" Building 7, or how the demolition could have been prepared in less than one day's time.
No explanation for why the insider trading on the airlines and WTC businesses affected was not investigated.
Instead, you've cited the most dubious suggestions people have put forth.
Until my response is complete, I suggest people that want to investigate matters for themselves have a peek through
