Goodness knows why these multi-million dollar cattle Barons and similar tempt fate on a near daily basis doing these types of things when a potentially more qualified and experienced 18-25 yr old will do it for nothing.
I did BFRs for a few blokes in outback Queensland, all PPLs. Their employer had put each of them through a PPL and a low-level/mustering endorsement at some stage and they were all very good pilots.
They heaped scorn upon "Keeping up with the Jonses" and the mustering practices demonstrated in that program.
Ironically I have seen far more "cowboy" flying from townies (self included) than I have from cattlemen.
