Thanks for some interesting stories, as always. I shall pass on the accidental selection 'on' of water/meth, to my nephew who drives J41s, many of them 'wet' equipped.
One example of a damaged engine still pulling strongly is the unfortunate Brit Midland 734 diverting into EMF. IIRC, the engine with the fire showed no other signs and operated as normal?
If I may, a fire-related question. When you discharge the bottle, where does it go?
Reason for question is: If airborne, and the bottle discharges into the core, then I would imagine that the extinguishant will be blown out of the back a split second later and not have time to have an effect?
