Prognosis is good, but now he is diabetic and our family doctor (and also
our Aviation Medical Examiner) says his flying days are over. Dad has had
many good years of flying, but is pretty sad about the "no more flying"
bit.

If he recovers to the point that his mind and reactions are still good,
there is always sport pilot. As long as he does not try to go get another
medical, he is still qualified to fly as PIC for sport pilot, if he can say
that for that day, he is OK.

Something to think about.
