As far as I am concerned, a good pilot is the one who flies his mission and returns to base safely. Now, how would you qualify who is best ? You have very experienced pilots and those with not so much experience. The difference will give the former more confidence, but will not prevent the latter from doing his job.
As MaxNG ( or is it MAXng, or MAXNG ) said, the ones who are taking their pensions have done their job. Good for them.
