The bottom line is referenced by the term "The Pilot in Command".
Who in Canberra is in any position to judge a midnight flight in NT when a mate is in grave and serious distress.
We really live in a "Nanny State" don't we?
If you consider it that serious, "JUST DO IT" and suffer the consequences later.
I've never been done for my last one. Good mate broke both legs riding a quad. Pig got at him while crawling nearly 8KM home. Chewed him up a bit. Night takeoff on the landing light from a claypan in a Comanche.
No VHF reception and the plastic cup from the HF is on the boundary wire at the last airport.
No phone, just yourself to decide.
What would you do?
