They never refer to this:
http://www.mdw.army.mil/news/news_photos/Contingency_Planning_Photos.htmlBecause if Pentagon officials prepare for a commercial jet - why should they use a missile ?
Because if Rumsfeld and the top officials are safe behind the girder of steel beams and kevlar in the wedge which was hit why should they not use exactly the object which they were prepared for ?
I notice the exaggeration for the socalled "physical evidence" which simply means: Let us ask for "WHAT really happened" instead of "WHO did it ?"
In effect it means to place speculations measuring the unmeasurable instead of the key question: "who opened the air space ?". The last question points to the culprits and it is possible to be answered. The question for "explosions" leads directly into the nirwana. And BTW nobody asks: "why did they need a crash commercial plane when the explosives were so neatly prepared anyway? And when explosions would directly point to the first try to make it by explosions some years before?" ("This time we succeeded ! sihnature Osama) Nobody asks for thousands of witnesses who must have observed the impementation of explosives to kill them - which might have caused one or two questions.
So my guess is: there is an interest in boosting "physical evidence". And lots of innocent people follow the nice photos and videos and more photos and ask senseless questions.
When "able dangers" will be the issue in congressuonal hearings in January there will be an interest too not to rise the question:
"who was responsible for the double existence, for the visa, for destroying evidence of the two Mohammed Attas ?"
(Atta #1 under observation of CIA, LfV, BKA in Hamburg, Atta #2 buying things in the BJ`s in Florida, in flight schools, having a girl friend Amanda and so on, all under observation of the "able dangers" officials). They cannot get out of this problem by dismissing i.e. the CIA as havong somebody else under surveillance.
Not to suggest interested sides in these discussions is, to say it mildly, funny.
