(1) "A photograph taken shortly after the strike on the Pentagon shows
that the hole made by the strike was far too small to admit the entry of a
commercial airliner."
The hole was actually 90 feet wide. I think you can safety fit the vast
majority of a commercial airliner through that.
See here for a fuller discussion:

anywhere in the vicinity."
What's this then?

(3) "We’ve been told that their names were on the flight manifests, yet
those that have been released have no Arab names on them."
This manifest appears to have five Arab names on it.

(4) "Also, other witnesses noted a missile hitting the Pentagon."
Not this one again. Link please.
(5) "NORAD explains this away by claiming that there were no fighter jets
on alert at Andrews AFB at the time. This claim is incredible, based both
on common sense and historical documentation."
Let's see that historical documentation.
If you are trying to discredit the 9/11 truth movement by mixing up the
few good points you make with a lot of crap, then you were completely
successful.
