Yes there is a picture, the engine (obviously shorn of outer parts) came to rest at the corner of Murray and Church streets.
So are you asking, as many people do, how is it possible all of the planes were able to penetrate through steel; and therefore physics dictates at least some of the aircraft structure ought to have fallen to the ground rather than than penetrate through the building?
That's a good question, and I've looked into it myself. Part of the answer is that the steel beams themselves need not have been broken, as the physics involved is not just determined by the fact aluminum is much weaker than steel. The physics is over my head to an extent, but it's complicated, and depends on the speed. For example there's a wonderful video showing a ping pong ball making a clean hole through a ping pong paddle even though the wood is obviously much denser. It was propelled at very high speed. In fact, water itself can cut through steel, and there's a video showing that too. At the very least it shows you cannot prove "aluminum cannot cut through steel" all. by itself without factoring in factor in the speed, the density and the strength of the materiasl. Further, the steel beams were held together by much weaker joists, which again would refute the claim aluminum had to literally cut through steel for all of the structure to penetrate the facade.
