Guldu Mohd, you r writing such a big story and you call urself a doctor. I really wonder whether you are one. u say no bldng can come down due to fire. Cant u imagine the heat generated by petrol in the flight and the impact of collission. What rubbish r u talking. Whom r u trying to convince? urself? or the bloody terrorists? some cracks made some movie, and u want the whole world to believe it. some craps wrote something abt white house being behind 9/11 u want to take that as proof. You must be a biggest FOOL.
