These omitted and distorted facts serve to render the official reports extremely questionable. It seems that facts were being tweaked in order to get closer to an explanation for the collapses. Even then the reports both failed to provide adequate explanations of why the buildings fell.
The buildings more or less fell into their own footprints, which is something that normally takes weeks of expert planning when a building is intentionally demolished and there are only a few companies on the planet that can do it.
Within each trade tower there were 47 steel columns at the core and 240 perimeter steel beams. 287 steel-columns in total. According to the official story, random spread out fires on different floors caused all these columns to totally collapse at the same time and at a free fall speed, with no resistance from undamaged parts of the structure.
Professor Steven Jones points out that the total annihilation of the building, core columns and all, defies the laws of physics unless it was artificially exploded:
"Where is the delay that must be expected due to conservation of momentum – one of the foundational Laws of Physics? That is, as upper-falling floors strike lower floors – and intact steel support columns – the fall must be significantly impeded by the impacted mass. If the central support columns remained standing, then the effective resistive mass would be less, but this is not the case – somehow the enormous support columns failed/disintegrated along with the falling floor pans."
