another good question. this is my theory.
could be two reasons. either a: maybe it wasnt a jet, maybe it was a missle, something smaller though still explosive. the administration might not want to let the general public know that somehow a missle got into this country or through our defenses for fear of causing widespread panic.
OR
the pentagon was used as a catalyst..an addition to the attacks on the wtc, which while would have been shocking to a large part of the public at large, wouldnt have been anywhere need as anger and revenge inducing as an attack on something like the pentagon..a structure that effects every person in the country..unlike the wtc. People feel differently about a serious government structure than the wtc...not less or more, just different...more 'deep' in some ways.
The only thing that would have caused more of an uproar was a hit on the whitehouse itself. A hit on something like that would assure that the O-K was given, or atleast partially, for the go ahead for a reason to move a massive amount of troops into a region that was already giving us a lot of trouble, and it would be easier to stage offensives when in that area than trying to get the logistics in place for an attack even from our east coast of any kind of size.
