to me...the question isnt whether or not a plane hit the pentagon...I honestly dont see any question about that....to me the issue presented is if it was a boeing 757
this is a link that is in that video

and some of the pictures there give an interesting perspective especially the 4th one down and the 6th one which shows where the tail "should" have hit and the fact that there is no damage to that section of the pentagon
