Mandatory retirement has been ruled age discrimination which is illegal in this country. It is a fact of life today and it will not simply disappear because some people don't like it. If some people object so strongly that they are incapable of maintaining a professional attitude with this new reality I respectfully suggest they should find another line of work.
You see, I agree with you that extreme personal conflict is not acceptable in the cockpit, but who do you think is going to have to adapt here? People exercising their rights or people who cannot let go of the past?
