Robert Fisk: Even I question the 'truth' about 9/11

I am increasingly troubled at the inconsistencies in the official narrative of 9/11. It's not just the obvious non sequiturs: where are the aircraft parts (engines, etc) from the attack on the Pentagon? Why have the officials involved in the United 93 flight (which crashed in Pennsylvania) been muzzled? Why did flight 93's debris spread over miles when it was supposed to have crashed in one piece in a field?

I am talking about scientific issues. If it is true, for example, that kerosene burns at 820C under optimum conditions, how come the steel beams of the twin towers – whose melting point is supposed to be about 1,480C – would snap through at the same time? (They collapsed in 8.1 and 10 seconds.) What about the third tower – the so-called World Trade Centre Building 7 (or the Salmon Brothers Building) – which collapsed in 6.6 seconds in its own footprint at 5.20pm on 11 September? Why did it so neatly fall to the ground when no aircraft had hit it?
