Not even remotely comparable
How so? It's a fast moving object constructed of mostly the same materials as the 757, both traveling at close to the same speeds, both impacting a concrete wall. The result isn't exactly the same because the mass of the two aircraft and the density of the walls are different, but the video demonstrates that large components of the aircraft are reduced to tiny pieces of debris. The point being, such an event is capable of completely obliterating the materials from the enormous energy release. You wouldn't have very large pieces of the plane still intact after impact.
Never mind the fact that in order to pull off the kind of complex, coordinated sleight of hand at the magnitude you suggest, there'd have to be hundreds if not thousands of people directly or indirectly involved. All would have to keep their mouths shut forever, and that simply isn't happening. That goes against human nature, especially when this would mean 2977 people were summarily murdered by the government. Someone always leaks.
Of course the government lies all the time. It's not a matter of "trusting the government," it's common sense, Occam's Razor.
