I guess when faced with deliberately landing at a minima lower than the legal one or running out of fuel and gliding to an off airport crash, I know which one I would choose.
None of the events in the past where QF landed below the legal minima, had any fuel to go anywhere else due unforecast fog. And I can guarantee an ASIR would have been submitted each time, but in all honesty apart from the Mildura event the ATSB didnt release a report as there was nothing to really report on apart from “The weatherman stuffed up”
