Anon, there is no missile in the arsenal that matches what is shown in the video - short of something like an Ares rocket, and the object in question would have to be flying at over a thousand meters per second to have anything close to a flat ballistic trajectory.
If you want to argue that they launched an Ares rocket at the Pentagon in a flat ballistic arc... Well... Have fun with that.
As for the pilot, it is rather simple to fly a plane. They are designed to fly in a straight line, usually, as it makes little sense for them to be built to fly in random directions. The pilot flew around the Pentagon a few times. This was not only to identify the pentagon, but also to identify the landmarks showing him what angle he needed to approach from. He was aiming for a specific side.
This is the detail they want to obscure. Why would a hijacker have a preference for the side of the pentagon that was hit? Well... What side was hit? The accounting department... How convenient. I'm sure lots of records and auditing work were lost. Oops.
The skill necessary to make the descent is "can you drive a car into the side of a barn?"
Yes. Yes you can. It's well within the flight envelope of the airframe (actually, very leisurely), and we are barely pulling more than half a G in any direction. Over level flight.
