I think people seem to be down playing the seriousness of the fire... how could you know it wouldn't go out of control?
It will be very interesting to find out the investigation and to hear the actual cockpit voice recordings of this incident... was there any evacuation talk, and who's decision it was to keep people on board..
On a side note - if people want to see how quick a fire can go out of control - china airlines landing in Japan -
