In my current airline we have had 2 serious incidents involving over 60 captains. We only have a few over 60 captains.
Airblue in Islamabad had an over 60 captain who ended his career (and some 150 lives) by flying into a mountain.
There is now a trend where pilots retire from their legacy carriers at 60, then continue flying in other areas/for other carriers. I expect to see more statistics from this rather small group of pilots.
Hopefully not as bad as the Airblue accident.
