I agree, a very sobering read, I was particularly struck about the SFF procedure where the aircraft is depressurised to 25000' to suppress the fire but then somehow you have to land at the nearest suitable airport without the fire being re-energised. Not having experience in freighters myself, the idea of operating a cargo aircraft without any active suppression seems an unattractive proposition. The idea of a FO with 77 hours on a 744F flying single pilot IFR (inside) is a powerful mental image, as you say, poor guys.
