At 10:14 a.m., fighter pilots receive permission to shoot down any commercial airliners that do not respond to direction, an order relayed from then vice-president Dick Cheney.
The following below sites seem to be very reasoned and rational in its examination of 9/11.

Prior to June 2001, the military protocol for errant aircraft over the U.S. was to default to intercept mode -- meaning, in the absence of any order, deviant aircraft were to be immediately intercepted.

In June of 2001, this standing order was changed such that thenceforth, ONLY an order by the Secretary of Defense Ronald Rumsfeld could activate an air intercept. In other words, if Rumsfeld doesn't explicitly give the order to intercept, it doesn't happen.

And, Rumsfeld is on record as saying that when the Pentagon was hit, he had no idea what had happened -- suggesting that he was "somehow" out of the loop altogether which is a lie.
If nothing else shows that 9/11 was nicely set-up, this should at least suggest it.

Alas, even presented with substantial information, most people don't care. Isn't the NFL playing today?
