I don't go along with the idea that making a mistake disqualifes someone. If it did that's gonna make it a short list. Anyways, even if the guy did screw up, he still got himself and the co-joe out of it alive. And he got back in the saddle and did it right the next time. Maybe its a cultural thing but Brits just love to focus on failure instead of success.
"because of their genuiness as people"?
Maybe that's an idea for another thread.
Anyways, maybe some folk are taking the question far too literal. Of course no one person can say who is 'the best' helicopter pilot in the world because no one person has flown with all the helo pilots in the world and even if they had maybe their not be qualified to judge.
There's no harm in asking if there's one pilot you've flown with who stands out as the best you've known. He or she may not literally be the best in the world but the best in the world that you know of.
Funny thing is while some folk are are criticizing suggestions and others are fussing about what the test should be, the guy here who's got the reputation of being one of the best helicopter pilots in the world modestly suggests the name of other pilots he's learnt from in his career. I reckon that's the right spirit to approach the question.
