The fire was contained to the wing. The fire services continued to fight and gain control of the "contained" fire. As soon as an evacuation is communicated the RFF will pull back.
When a door opens the cabin becomes exposed to the fire that is no longer being either controlled or contained. There is no guarantee that a door or doors on the side of the burning plane will remain closed, thereby exposing the inside cabin to smoke, fumes, heat and flame. There was certainly potential for fatalities.
This outcome was excellent. I hope we learn the facts about the cause and can rectify any possible recurrence.
I am very glad it was not my arse sitting in that cockpit having to consider all of the immediate options whilst a fire was burning......
A reminder that what pilots and crew do every day is still actually dangerous and can kill you.
