The French article would seem to indicate that there were no passengers on board the postal freight F27.
One anomaly that existed between F27 operations in Europe and in Africa is that water methanol never seemed to be carried in Europe and in the UK. I wonder if you can even find it these days?
If WM were ever to find its way on board, in at least one major UK F27 operator, the Ops manual directions for its use were quite in contradiction to the Fokker F27 manual where, if memory serves, all approaches were made with WM selected ON in order to furnish max power for a go around. Take offs were wet or dry of course and the dichotomy then lay, in the event of catastrophic engine failure, in having to reduce power on the operational engine to below 14,700RPM(??) engage WM and then power up again to max.
Useful stuff that, which in moderation gave an added boost to a V8 car engine.
