Surplus is No Excuse
Why should a pilot 'surplus' have any bearing on laws that allow or restrict airline pilots from flying over 60? You imply that if their is a pilot 'shortage' the rule should be changed. Do we change it back if there is a recession and there's a surplus again? That's nuts!
If someone is healthy and competent, why retrict their career? In any other industry (in most countries) that would be illegal and the unions would pitch a fit!!!
60 as an age was yanked out of some Amrican bureaucrat's butt almost 50 years ago. Now the Americans are among the last to amend the rule.
Time they got their act together and moved into the real world with the rest of us!!!
