Again you ask the wrong question
YES! I am saying that that particular set of circumstances has not happened before:
THAT batch of fuel
THAT powerplant/airframe combination
THAT temperature for
THAT duration
and THAT is why I keep saying stop focussing on THAT powerplant and look at the entire set of circumstances including the fuel.
You are obviously intelligent... why are you thinking in such a one-dimensional way?
