FANTASTIC!!! (I'm not being sarcastic, I'm really interested) I was hoping to discuss this with someone who actually has the credentials. The hole in the outer wall of the outer ring - the initial strike point of the projectile; plane or otherwise - was about 14-16 feet wide (according to relating the size of the fire engine to the size of the hole in several pictures). Now each ring of the Pentagon has an outer and inner wall. Each wall is approx. 18" thick. This is steel reiforced concrete. That means that the impact point was 36" of steel reinforced concrete. This means a total of 9' of steel reinforced concrete from entry point in the outer ring, to the exit point of the inside of the inner ring. Could a 757 have punched out a 14-16' wide hole on entry and have pierced 9' total of steel reinforced concrete to make a hole of almost exactly the same dimentions?

Now the nose of a plane is not made of reinforced aluminum or anything of the sort. The nose of a plane (the part that would have been doing the punching) is called a "crashdome". This is the area of the plane that is below and infront of the cockpit; the area that would first impact. This crashdone is where the plane stores electronic navigation equiptment. To enable the transmission of signals, the nose is not made of metal, but carbon. It's shape has been designed to be aerodynamic but it is not crash resistant. The inside casting, as well as its contents, are extremly fragile. The nose would crash on impact with an obstacle, not penatrate it. You NEVER find a nose in a crashsite that involves a head on colision (the type in this case). THEREFORE, it is impossible that this carbon nose punshed a perfect 2.5 yard diameter circular hole in the steel reinforced buildings.

As for the WTC, I agree that it is an engineering conundrum. I'll meet you on the "what happened on 9/11" thread.
