This is an interesting subject.
I do believe that as a wild ass colonial and thus simply an "honorary British subject" I should leave any attempt at meaningful comment to my many friends in the United Kingdom.
I will say however that the tag of "Living Legend" is not one to be bandied about loosely in the world of aviation where there exist so many worthy of the title not having officially received it.
I'm not at all sure what the right answer should be for Harry. There are good and not so good things that can be said about his life, and anyone's life actually.
I think were I Harry in this instance I would consider the company I share in my aviation world and politely and respectfully decline the honor while thanking those responsible for their consideration.
