Unfortunately due to the nature of this industry and associated ego issues, the jealousy is actually unsurprising and some of the comments here are unworthy of apparent professionals. Personally, I think that the antipodeans etc are absolutely correct in that medical fitness and competence should be the sole arbiters of continued pilot careers. In an era when anything that ends in - ist causes outrage in the permanently offended but ageist appears not to be in the lexicon.
