Absolutely. Lightweight aluminum structure, filled with very heavy jet fuel. It would certainly have the mass and velocity (momentum) to punch through a rigid by relatively thin facade and not have the structural robustness to remain intact.

Yes it ii]dis-integrated, it did not vaporize. Seat cushions are less dense, have little momentum when dis-integrated from their fixed structure and would be easily ejected at an angle to the crash vector by air resistance and the low speed expanding jet fuel conflagration.
