They have hardened DU noses so that they can penetrate 20 inches of concrete,

20 inches? I take it you've been inside the Pentagon and seen the actual thickness of the walls?

Maybe the support columns, but not the walls. The walls of the Pentagon consist of 5 1/2 inch thick limestone "facade" over an 8 inch thick, UNREINFORCED, brick.

But as part of the renovation, the walls of the renovated "wedge" were braced with an external metal "skeleton" in order to prevent collapse of upper floors by transferring bearing loads from the supports, should lower floors receive blast damage.

And you have to bare in mind is that once a hole was created by the denser sections of the airframe (fuselage and engine nacelles), the weaker portions of the plane followed into the building by way of momentum and the initial suction created as the fuel exploded and expanded throughout the lower two floors and upward between each ring of the Pentagon.

The wall, had it been 20 inches of solid concrete, would NOT likely have been penetrated at all by a 757, and YES, THEN the blast would have reflected off that wall and backward, scattering more debris outside of the building.

But the path of least resistance for the blast, once perforated and and inside the building, was laterally and vertically (between the rings). It was NOT through the entrance hole.

And yes, there was considerable molten, and shattered, aluminum debris found strewn throughout the collapsed portion of the wedge during debris removal. The pieces were quite small.

I take it you haven't bothered to look at the photos and stories contained in the following link:

As for the direction of attack, I also have often wondered about this, given the fact that other portions would have far more valuable to target. But hitting any part of the building from any direction but the south would have instantly sent out alarms since it would have either required the plane fly over restricted DC airspace, or into the flight path of Reagan National, risking a mid-air collision that would have defeated the purpose of the mission. So the southerly approach was the only one logical for the pilot of the plane.

As for G-forces in that bank, this guy did some calculations and found that the force measured about 1.35 G's.. not particularly excessive.
