Dear John and Five Doves,
I have presented the following information to Five Doves before but it looks like it is necessary to do so again.
 
My husband was assigned to the Pentagon when the plane was driven into its side.  Although by the grace of our Father we were out of town that day my husbands coworkers were having a meeting in the building of the Navy Annex that was closest to the Pentagon at the time it flew over.   The plane must have passed within inches of the roof of their building so when they heard the loud noise they all ran over to the window to see what was making such a big noise just in time to see the PLANE crash into the side of the building!  They told my husband of the events when he returned the following week--there was no reason for them to lie to or make up a story for him.
 
I also had a friend that worked in DC at the time who was driving into work and saw the plane flying over her (she was driving in on 395 into DC) and go down into the horizon.
 
There were tons of eye witnesses that reported what they saw in the days after.
 
Also I think that the comment that the plane was used as a missile could also be the way military people would refer to the form of it because it in fact became a projectile/missile even though it was not originally intended as a missile per se.
