I have never flown an MD80, or any Douglas aircraft, and I am unlikely to (not because there is anything wrong with them, just that they are unlikely to be added to the fleet of my current employer), therefore I cannot comment on the engine fire drill quoted by md100. I confess to being surprised, but I did say I stood to be corrected.
However, on my current type and both previous aircraft, the fire drill included verifying which engine, then at the appropriate time always shutting it down.
If MD fire detection systems were so robust as to allow an alternative option as listed by md100, then this would account for some of the respect shown to them by md- and dc- pilots.
