@Piltdown Man,
I am merely an observer of both the FlyBe incident and the Emerald Accident and am not qualified to make a detailed critique of flight deck action in either case. I do though stand by my comment that a longer time in the air would certainly, or at least very probably, have been catastrophic in the circumstances of G OJEM.
The AAIB report at Conclusions/Findings point 2 refers to an immediate substantial nacelle fire. At point 4 of conclusions it refers to significant leakage from the fuel heater and fire which posed a considerable hazard to the aircraft (my bold/italics).
The crew were alerted to the fire by the cabin crew via interphone (AAIB report p3).
