"Don't think the Saudi TriStar fire is a fair comparison, that aircraft was clear of the runway and could have evacuated if the crew had depressurised and allowed the cabin staff to open the doors"
Fair point, but the Saudi accident is a great example that highlights how rapidly a fire went from a warning to the destruction of the aircraft so quickly.
The China Airlines 737 explosion in Japan changed my view about fire and evac. Things can change so f&%*$# quickly.
