There was a case back in the early '70's where a MMA F28 diverted to Fitzroy Crossing early one morning when Fog rolled in at destination Broome and then Derby (almost unheard of) and he was forced to divert. A very interesting story, as I recall with the hospital staff putting the flares out at ~0300 and the aircraft arriving when there was only a single path laid. His first approach was to the wrong side of the flares.... the second approach was good, but one engine reportedly flamed out on the ground....due lack of fuel!
That Capt was noted for always carrying an extra 1000lb+ for Mum & the Kids....
Under today's rules and SOP's and management policy/direction, they may have lost the a/c???.
As one senior pilot I know has said more than once... Lad, they are fuel tanks not air tanks!
