Your link, as was expected, ignores completely potential energy. Meaning the buildings were designed to hold up against the forces of gravity and much more. It's true they weren't designed to withstand a dynamic load being dropped directly on top of them at a reasonable rate of speed, but cars aren't either and they still usually manage to not turn into dust before collision. And the initial impact would have been @ significantly lower speeds than 90m/s as suggested. And there's still the fact that the buildings potential energy was enormous in itself.Oh you mean like a FUCKING 450 MILLION KG building falling down?
Before collision you say ? YEah, because their hypothesis pretty much relies on the existing building providing no resistance at all
A long freight train at speed has unbelievable amounts of potential and kinetic energy too (not near as much as the example above, but more than enough to make the point). Yet if it comes off the rails chances are it's still going to resemble a train or a bullet train, same deal. And the calculations on that page are wrong anyway. The initial impact velocity would not have been 90m/s. That would have been the velocity at the bottom of the fall assuming 0 resistance from the building which is ridiculous. And since they ignore the resisting force of the building completely in their calculations, well... they're just wrong.
There was no reason for the building to suddenly completely fail like it did. You can scream about the planes and fires all you want, the temperatures of the fires - based on the very limited evidence collected, were not high (black sooty smoke, very few visible flames and the NIST report itself tested the limited samples they had and only a handful reached any kind of noteable temperature level) and the damage from the planes obviously wasn't extensive enough to significantly structurally impact the the towers or they wouldn't have stayed standing like they did for hours without a sign of faltering (and people claim otherwise but there is absolutely no video or photographic evidence of such faltering).
The concrete was dust loooong before it ever hit the ground also, indicating force was applied long before the impact you claim to be responsible and while the top halves would still have been in one piece hypothetically, so unless the building offered a lot of resistance that would have been an impossibility and if it offered a lot of resistance it wouldn't have fallen so quickly anyway so it's all contradictory, which is why I bring it up. It was found miles and miles from the site as well (further evidence it was dust long before impact).
It also negates to mention that 9.8m/s2 only applies in a vacuum. Wind resistance must be calculated and can account for some of the time difference, which is not a lot anyway.
