Number one priority when you have a fire - - Fight the fire immediately. Good thought, good priority, but with a two man crew, not practical, particularly when the fire is below you on another deck, or even behind you on the same deck. I question how effective a bottle of halon, dry chemical, or water is going to be if such fire is producing smoke to the extend that visibility is limited or not possible. Smoke hoods may provide O2, but will not aid in visibility under those conditions. Thus, an axe, knife, or other tools will likewise provide little assistance and value. Putting the airplane on the ground is paramount and an airport is always a nice choice. This crew attempted to do just that.
