Right... so please explain these studies of cognitive decline in older pilots and why did they lead us from from Age 60 to Age 65 at the worst possible time in our industry, and then 7 years later, in light of even more studies, why did the Feds scrap the rule requiring at least one pilot to be under 60?

If this comes to fruition, and there's no way that it doesn't if ICAO goes to 67, the Feds will simply do what they did once before - require one pilot to be under 65 and observe what happens, and within a few years, they'll scrap that rule as well.

If I were placing bets, at some point, the whole mandatory retirement age is gonna disappear altogether just like it did in a number of other countries, and it'll be a simple question - can you pass your recurrent training, and can you pass your FAA first class medical? If the answer is yes, you get to keep on flying. If not, happy retirement.

Perhaps that's why we should concentrate on contractual improvements to proactively account for this possibility as opposed to being reactive.
