In the states, the age 60 rule was never based on health, safety or proven with scientific data. It was an attempt by the head of american airlines to get congress to get rid of his older more expensive pilots for him because he was not able to figure out how to do it himself. And congress and the Caa did it! We have been stuck with the rule ever since. Early on in my career I flew with many pilots from Branniff airlines who were forced to retire at 60. These guys could run marathons and fly circles around all of us young pups. Age 60 is wrong, has no basis other than history, and should be changed.
Unfortunately, ooizcalling, it will be ALPA that muddies the waters.
