Are you saying 300,000#'s of 1/16" thick aluminum, steel and fuel traveling at close to 500mph didn't cause any damage?
No, I'm saying the front of the fuselage crumpled on impact like the crumple zone in a car, but even more so. When it hit the wing box and engines, and wing spars it ran into some heavy material. Engine are cast and weigh about 20,000 pound.
The absolute heart of the matter is the first thing that went down when the first tower collapsed was the antenna at the top. That's critical because that was bolted to all the strong center columns in the middle of the buildings. It free fell meaning all those massive columns had no resistance. That can only happen if they were detonated and cut using Thermite. It was the design engineer of the building that was questioning how that was possible.
This was an expert job and I believe they used explosive and Thermite on the impact zone as well.
The smoking gun is how fast it fell with no resistance from the massive steel columns below.
