Re: Questions about 9/11 that you still dont have answers to
He is not using logic, why should I? He is claiming that a sky scrapper was built on gas lines and designed in such a way that one explosion of gas pipes could bring the whole structure down. He is trying to make me believe that even 8 hours after the collapse of tower 1 and 2, gas pipes still had gas flowing through them and no one bothered to shut them off.
and just for his knowledge, bridges are also a fail-safe design. Failure of one column can make a bridge unsafe to operate, but its not going to bring the whole bridge down.
