He died. He was 90 years old.
What was he doing with a Pilots License at that age?
Think about it. He is not piloting for hire. It is, or was, a free country. I have two friends pushing 80 that do quite well with their aircraft. One of them has a high speed Moody she flies everywhere. The other is a guy that just built his second experimental which he just got pontoon qualified.
Flying.
A pilot license never expires.
If you can pass the FAA’s flight physical, you can get a pilot’s license. He certainly had many decades of experience.
Years ago, when I lived in southern California, there was a commercial on TV for Glendale Federal Savings.
In one of their commercials, they showed a man named Ernie English who was flying an open cockpit biplane.
Ernie, at the time, was well into his nineties.
If you can pass the medical and the Flight Review every two years you can fly. Our chief flying instructor at our club is in his early 80s. I am 76 and had to hang it up as an instructor due to heart problems. I am still very competent but if the heart went wrong in the air I could kill my student, myself, and wreck a perfectly good aircraft. Oddly I can still do flight reviews with a current pilot. He is Pilot in Command. I can no longer instruct.
