SHOT-ONE way off again.Safety critical component is the pilot. Safety critical component is, also, many mechanical units. Extending the life of a hydraulic pump because of heartfelt issues in the pump department has nothing to do with this discussion. Extending the employment life of a pilot because of heartfelt issues has nothing to do with this discussion and has been, by many posters,clarified. Indeed, by openly discussing "heartfelt" issues, light is thrown only upon the reasons why some pilots might welcome an extention to the retirement age but would never be the reason for doing so. You are missing the point that the current, REGULATORY retirement age is 65 and it definitely Is ARBITRARY. You claim that risk of medical issues etc increase rapidly after age 65. Really ? Show us the evidence as related to PROFESSIONAL PILOTS who are very carefully monitored, TWICE a year, medically and extensively monitored in terms of competence throughout the year. To bring you back to the point, THAT is Captain Bayley's case. Having shut-down his engines on his swan-song, why, on earth is he barred from doing the same trip, the very next day, just because he is 65 ? Oh, it is, because, as you claim, not arbitrary but based on deep study showing that his chances of medical issues affecting his licence capability increase after age 65. Nope, see no evidence in the case of highly monitored professional pilots. Now, do calm yourself and focus.
