Not the first time that a wealthy pax takes a final ride in an old piston engine aircraft when they could have easily chartered a fully IFR turbo prop. Mt Hotham, Menagazzo in the Chieftain and now this. Flying somewhere is not like hiring a stretched limo. There is also the issue of pilot age. Sorry, but the older you get the more your skills and cognitive abilities reduce. At different rates but they do deteriorate. Experience only gets you so far. On the day you are only as good as your last decision and the older you are the less agile your decision making is.
