It is highly unlikely that piece of fuselage traveled through heavy structural steel walls at 545 mph. It would be badly gouged by the steel in a linear pattern along its horizontal axis and almost unrecognizable as a fuselage piece. How did a short light aluminum fuselage piece maintain the inertia after traveling through two strong exterior walls and multiple interior walls, to fly over a hundred yards through the open air to the roof of another building off to the side? It could not. It was planted like much of the other evidence of 9-11. Not my point to argue with SP, but just a little physics here: Supposing the fuselage piece to be emerging horizontally at around 780 feet above the plaza (78th floor?) and landing on top of a 9 story building (about 90 feet above the plaza) would make a vertical drop of 690 feet. Using y=(1/2) g t^2 for the equation of vertical motion: 690 = 0.5 * 32.2 * t^2 gives a time in vacuum of 6.54 seconds. Using a conservative horizontal travel distance of 400 feet and a time of 6.54 seconds, and a horizontal equation of motion of x = v t: 400 = v 6.54 then v = 61 feet/second or about 42 miles per hour as a necessary horizontal velocity on leaving the North wall of WTC 2 (in vacuum, of course). Since a piece of debris that large would experience considerable drag, a higher velocity value would be needed, however an offsetting longer fall time would also result from the drag. Given the original velocity on the order of 500 mph, this does not seem like an unreasonable event, just on the surface of it.
