The front part of the fuselage disintegrated on impact, while the mid and tail sections moved for another fraction of a second, with tail section debris ending furthest into the building. In all, the plane took eight-tenths of a second to fully penetrate 310 feet into the three outermost rings and unleashed a fireball that rose 200 feet above the building.
0.8s? I could be forgiven for busting your chops, but, how do you know this? Did you study some part of the FDR Frank Legge & Warren Stutt (and me) are unaware about? Plane impact analyses, while way more useful than mere conjecture about collision dynamics, come up short in several areas, such as modeling the RB-211 turbofan engines realistically.
