Certainly, a friend of ours who has had to stop flying at 60 would put a lot of twenty-five year olds to shame in the physical fitness stakes. His mental agility remains undiminished, having enjoyed a career that kept his brain in trim and I would have every confidence flying as a passenger in his machine!
He was kind of hoping that his airline would still allow him to position aircraft, but, sadly the insurance proved prohibitive so he is now frustrated and desk-bound - shining his trousers at head office every day!
In this day and age, it is high time the flying community was treated in the same way as any other working group regarding retirement!!!
Good Luck!!!
