I remember Geoff Timms still flying Harriers in his sixties!!!! I believe he finally retired aged 62. He was meticulous on his walk rounds and had eyes like a S*** House Rat!
Pat King was another, he could make 6600lbs of fuel last longer than anyone! Just tootling around, we often used to think he was overdue. The old saying old pilots and bold pilots used to spring to mind.
