Blue skies Duke. As well as being inspirational these were also damn good stories and must be one of the most enjoyed threads ever on Pprune.
I saw something written yesterday that made me think of Duke: "Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - Wow! what a ride!"
From Dukes stories I'd guess he enjoyed his ride. RIP.
