I'm sure of this. You haven't been able to convince anyone here, anyone who has knowledge in the field of structural engineering anyway, that you're correct in your assessment of the collapse of the WTC towers. Either there's a serious error in your position, or you're wholly incapable of communicating your position in a way that others might understand it. To put it simply, either you're a crappy communicator, or you're just plain wrong.
So if you believe you're correct, and it appears you do believe that, you should go take some language skills courses and learn how to communicate your ideas in a way that is understandable to other people. If that's not the case, and if you're just plain wrong, the likely scenario given the direction of the discussion and the evidence you've provided (or not), you should just STFU.
Either way, continuing to babble what seems to be an ongoing stream of nonsense clearly isn't helping to win you any converts. Nor is it providing any advantage to you or to the two or three obviously ignorant Truthers who seem willing to rally behind you on this issue. Frankly it makes you all look like idiots.
You are sure? Pls, provide evidence that a structural one-way Crush down is possible! That will settle the matter.
