@ Avturboy....I absolutely agree with you , prevention is better than cure, however, you say yourself, it continues in your 25 years experience.
All pilots hope never to have a power-failure at takeoff (see what I did there! even covered the snapped glider tow cable) but they continually train for that event. there are many other scenarios where , although one hopes "it'll never happen to me", the scenario is, nevertheless, rehearsed and a mitigating strategy practised.
My post was in the same spirit, IE- Is there anything a pil;ot could do to increase the possibility of keeping the donk turning and burning on the wrong / contaminated fuel. I am well aware that a turbine can run on just about any combustible liquid, though this may seriously foreshorten operating life.
