Last I saw of Ron Kuch was in 1989 when he operated a Cessna 310 at Cairns. Quite a character. He and his German born wife lived in a caravan under the trees somewhere near the airport. She was a real honey proving that you don't have to be good looking to win the blonde beauty.
I think his charter business was closed down around 1989 by the regulator of the day. I was told by a former commercial manager he ditched an overweight Nomad in the Marshal Islands with freight, baggage and people sitting in the isle. Normal practice in those days. My guess he would have been around 70+ when he died.
