Wasn't being specific about the fire cause, just interested in any thoughts of pro's/cons in restarting.
I'm assuming the 777 same as 737 with 2 bottles that can be fired in sequence as/if required.
If you'd had a fire but only fired one bottle - why wouldn't you try a restart?
If you'd had a fire and had fired BOTH BOTTLES to extinguish? Now the question gets more interesting.
Apologies if the 777 is a very different system to the 737.
