Overt Auk,
I think the other pilot with Stuart was Roger Williams wasn't it?
I don't think you can generalise with test pilots, SAR or military pilots. I remember one former test pilot some years ago who managed to 'toast' the engine of a B206 because of a certain lack of skill. I have little more competence than the average Ukranian tractor driver despite being both ex military and SAR
.
From the posts I've read here Valérie André seems to be a strong contender, but who really knows, and by what criteria is this pilot-amongst-pilots to be judged?
