The real Queen of the Skies will always be the Wessex 3. The autopilot and flight control system were the equal of anything flying today in terms of accuracy and reliability, even in those days of selsyns and resistors. I spent 1000 hours at 200 feet and below much of it at night relying on the autopilot without a hitch. Only the engine let us down once and that was near Gibraltar, so the water was warm.
As for the Whirly 7 referred to by MBJ, I remember solo wet winching in Mounts Bay as a Midshipman with all of 75 hours on helis where the winchman would go down on the wire wearing a long lead by which to con the pilot to the survivor. Such faith in a sprog pilot would surely merit an award these days. Names like Kentspear, Mooney, Quinlan amongst many others served course after course of embryo pilots.
