Incorrect. At the 87th floor where the first plane hit, the steel ibms were only a quarter inch thick. Solid aluminum substructure, which most definitely is thick beams, although made of aluminum to save weight, traveling at a high Connecticut energy, would have most definitely gone into the building very much Wiley Coyote outline
I don't think the jet nose cones are solid. It is an aluminum skin with various instruments inside.
You may be right about the I-beams. I just don't know. But after seeing what a bird strike does I have a hard time believing that a jet nose cone can hit concrete and still not distort.
I have a hard time following you. The vertical structural elements are columns, the horizontal structural elements (floors) are beams. These are different structures. Penetration relates to momentum and the wings would have had less momentum per unit area than the fuselage and engines, so they would not penetrate very far. You haven't seen aircraft primary structure (wing beams & decks). Very robust. The building outer wall was mostly window, so there was no possibility that a Warner Brothers effect would have occurred. Too much smashed glass. I think you are trying to refer to "kinetic" energy.
It is a common mistake to think that the terminal effects of a collision or a bullet wound are proportional to kinetic energy, but they are more in proportion with momentum. What is left out of consideration is that a lot of the kinetic energy is converted into thermal energy of material deformation of the penetrator. When my Dad went deer hunting, if they bagged a deer, they would cut out the bullet and drop it in a bucket of water to cool down. The wounding deformation of the lead and copper made it hot to the touch.

I don't even question if jets hit the towers. I just don't buy that that is what took the towers down. Take a look at Melania's coat during a 9/11 event. the stitching looks like the nose of a plane coming out of the tower. https://www.ndtv.com/world-news/white-house-slams-backlash-over-coat-worn-by-melania-in-9-11-tribute-image-report-2100363
