You can't argue with undeniable facts and evidence. I even have the registration record on hand for the airframe of American 77. It is like this, there is much that I know, and much that you do not know.
Then show your evidence and credentials for all to see and put the mystery to rest.

The aircraft crashing into the pentagon was the equivalent of an aluminum can being crushed, not a knife being thrown. THAT is where you are completely wrong.
Take an empty aluminum can, put it on the ground, put 2 rocks on either side, now stomp on the can in an angle where you will also stomp both rocks. What gave more resistance the can or the rocks?

i didnt know that a 757 consisted of 0.11mm thick structure that sure is news to me.
that aside.. the knife is not being thrown, the knife is an analogy describing PENETRATION POWER.
i am trying to describe force distribution to you. what is easier to penetrate a concrete wall
1000 Newtons concentrated in 1cm^2
or 1000 Newtons concentrated over 100cm^2?
have you ever seen a guy lie on a bed of nails? its the same principal.. a bed of nails distributes his weight over many nails, but if his entire mass was over a single nail it would penetrate his skin.
what you see in the pentagon crash is the entire mass of the aircraft being focused at one relatively small area. where as the wings and engine is spreading its kinetic energy (already less than the initial impact) over a larger area.

Then let's take a look at this photo.
B-25 Impact Hole
There is only a couple inches separating you from the outside of the plane. How thick do you think an aircraft is?

It depends on the location on the fuselage because the skin thickness can range anywhere from 0.040 to 0.125 thousandths of an inch .
Now, if you are talking about the nose radome of fiberglass or kevlar, then you are talking greater thickness and remember, kevlar can stop bullets.
