In my humble opinion of course, any use of the word "fire" where incidents are concerned reminds me of one occasion where time WAS of the essence (although the lack of urgency was not judged to have affected the eventual outcome ) . . . Swissair.
When I did my 1st jet rating on the DC9 back in 1988 my trainer in the Sim said to me "you have one thing to remember more than any other in any of the fire checklists . . . LAND"
I believe his advice was sound (although more than likely influenced by an occasion when an uncontained failure on a Viscount nearly burnt the wing off by the time they completed a very short circuit back to land on the x-rwy at LHR.)
