The disappearing planes on 9/11

One thing that struck me today is how little plane debris was left from the four 9/11 plane crashes.

Sure, according to the official story, flights 11, 77 and 175 crashed into buildings, and clearly the planes blew up during these crashes. And in the case of the WTC, the plane debris would get jumbled in with building debris. So that's understandable. Less understandable is the lack of plane debris at the Pentagon, but fine, it blew up and broke into tens of thousands of tiny pieces.

But this is what gets me-- flight 93.

What are the odds that this plane would go down into soft ground such that the plane completely disappears?

This means that for the four 9/11 planes, there is not any clear picture of the remains of a plane. Not one. Maybe it is just chance, but I have to wonder if in the case of the 9/11 planes, particularly flight 93, there was something they didn't want us to see about the planes.
