And some unknown but rather small parts of the aircraft?
And would they have been spread out on the grass by the suitcase carriers before whatever made the impact on the Pentagon, or after?

I'm not trying to push some conspiracy, it's just something that has always been sitting there with a questionmark hovering over it, and I've never found anyone who had enough technical knowledge to explain it to me. Any idiot can face a crisis - it's day to day living that wears you out.
the parts are pretty heavy, mechanically fitted together, wired into place (every bolt has to have wiring around it so it doesn't loosen) and many of the parts are designed to withstand extremely high temperatures
the Pentagon is reinforced so it would not replicate the same conditions, but there would be some similarities to your incident
maybe if you could give us some more details of what you remember about it?
In Dodo's links you'll find those pictures of the damages on the outer part of the building. The structural damages were mostly at the ground floor and is consistent with the flight path and height level (in fact the plane must have been on a an air cushion effect, "effet de sol" in french).
One of them, left wing, chunked out a bit of concrete railing and the right one hit the generator (two structures at less then 1m and 3m high respectively) and went inside (picture of one engine inside the wrecked building) through the ground floor part of the facade.
Not surprisingly, the pictures show that posts and beams are damaged much further then the central big hole... (the famed wing problem)!
The Pentagone building shape and built technique had the same effect (my feeling) then the multiple layers of plastic sheets used to stop a bullet in forensic tests... The shape charge effect of such a plane at such a velocity would have otherwise reached the central courtyard. While it seems that only two holes were blown up on that side (either perpendicular corridors, or part of the engines)!
I would agree with some that the chances to hit the target, flying so low and in such a short distance to maneuver and align the plane is really hard to achieve even for a trained fighter pilot !
