Yes, unfair on Dook. No to the compiler question. I certainly use the maps from Flight Radar, and a touch of Welsh deviousness. Hard luck dook, I tried to point - W-O-W refers to the nearby Wanaka on another lake, Wings Over Wanaka where Sir Ken once displayed. My own Ken Hayr story, apart from his being my Air Officer Commanding, refers to his double-hush in a turbine twin, but that is for another time.
With cheerful regret, to you Cows.
