agreed. occam’s razor applies. the simplest explanations are either that it was a plane that crashed into the pentagon, or that they shot the plane down over pennsylvania, or the plane crashed because of the struggle with the pilot.
al quaeda missiles, if they were launched within the us borders, would be a much much much scarier scenario than ever thought, and show that there is virtually no way to “keep our borders secure”, whatever that may mean.
Moderator’s Note: We have a newly started thread on this topic, Is someone else responsible for 9/11?, so I’ll close this bumped older one and direct continued discussion to the new thread.
