I think we should all look at this suspiciously. The hits on the WTC showed that these guys did their homework. They knew where to hit the building to weaken its structure. Is it such a stretch to think that they may have sabotaged airplanes to fail at some later point in time(by extensive studying of the planes) by compromising a critical part of an airplane.

They did find mechanic ID's on some of them didn't they?

"They knew where to hit the building to weaken its structure."

If the object was to bring the towers down, don't you think they would have come in even lower and tried to hit it as far down as they possibly could, so there would be more weight resting on a weakened structure below?

Knew where to hit it indeed. I don't suppose you have some testimony and/or evidence which supports this theory?
