AbsoluteFokker, would that not have made this a Fuel Starvation Event rather than a Fuel Exhaustion Event? Only way I could still see it being Exhaustion is if the Fuel onboard is then considered not usable due to the Fungal Growth but if the Fungal Growth fouled up the fuel intakes or some such it would then be Starvation, putting that particular one down low on my own list of possibilities, also wouldn't explain why a Pilot got the boot unless there is something more to that part we don't know which is always highly likely!
