I have flown with lots from all over the world, and the best I have ever seen is between two:
Byron Graham, former Chief R&Dpilot for Sikorsky, and a Marine Corsair pilot in WWII. Civil engineer, and crackerjack TP in every way.
John Dixson, recently retired Chief Pilot for Sikorsky, and an Aero Engineer from Notre Dame, US Army combat veteran (he was at LZ X-Ray, if you saw the movie "We Were Soldiers") and the fellow who guided the S76, S92 and Black Hawk thru development and into production.
In the running, Gui Dabadie of EC. If there is someone on the planet better, I would get chills.
