Thanks for answering.

For those who are really interested in theses things, please google MASCAL to get a maybe different point of view.

Short summary from Wikipedia:

“The Pentagon Mass Casualty project (codenamed Pentagon Mascal) was a mock terrorist contingency exercise that was held in the Office of the Secretary of Defense conference room from October 24 to October 26, 2000. The exercise required emergency response teams, members of the defense protective services, and U.S. government officials to conduct emergency simulations in preparation for a possible plane crash into the Pentagon.”

Maybe someone should have told Mrs. Rice about it.

In case anyone reads Tom Clancy, for example “Debt of Honor” written in 1994, you will read about a jetliner killing the president.

Ok, Tom Clancy is not the government.
To round it up, I don’t believe in most things some others do, like “missle in the Pentagon” (where is the plane? - burned, as aluminium burns), or controlled demolition (does not affect anything).

But I strongly doubt the official conspiracy theory about 19 (comparably dumb) people killing 3000. This has been done by some very intelligent people.

[[You are resposible for the protection of the Pentagon and all of the people inside, including Mr. Rumsfield.
You are informed of one tower burning. Then the second tower is hit by an airliner. What do you do within the next five minutes?
a) Order protection measures of the Pentagon
b) Evacuate the Pentagon, possibly to under the earth bunkers
c) a + b
d) nothing of the above]]

Probably d, since I would have no reason to think an attack on commercial buildings in New York would portend an attack on government buildings in Virginia.

[[How could it be that a missing jet had 35 minutes time after the worldwide TV tansmission of the second impact to finally crash into the heart of the defense of the USA?]]

Well, if you multiply the jet’s speed by the time involved (35′), you get a maximum value for the linear distance it had to travel to hit the Pentagon. The area is then that distance, called it R, squared and multiplied by pi. Compare the area of a jetliner to the area involved, note that most of the country is not under radar surveillance most of the time, and you’ll begin to understand why it’s a much harder problem than you might think.

The CIA headquarters at Langley, VA has huge plate glass windows in front. They don’t expect a domestic attack (though in fact they did have some crazy guy take a shot at them a couple of years ago). Neither did the Pentagon planners. There hasn’t been an internal war in the United States since 1865.

[[Come to mind are possible hints they ignored of the impending attack (as yet unrevealed) and the reason Building 7 would crumble when no plane hit it and suffered only a few office fires (it MUST have been a controlled demolition).]]

Building 7 was not hit by the planes, true. It was, however, hit with debris from buildings 1 and 2. So no, there’s no way it MUST have been a controlled demolition. From the films, it clearly is not, since in any controlled demolition, they blow out the first floor and let gravity collapse the rest. Have you looked into how controlled building demolitions are done?
