How is it that you reached that conclusion
that is the PENTAGON was not the primary target?
If indeed the wall of the pentagon had been re-enforced
to resist missile attack, please note that an aluminum airliner
is NOT a missile and can not be expected to perform as a missile,
therefore ... WHY the total penetration by said airliner?
there is something VERY wrong with this picture.
The whole place held up for hours with all it's supports and foundation knocked out... There is nothing 'wrong with this picture', your just spouting BS and hoping something actually sticks.
