There are old pilots and low-level aerobatic pilots but there are no old low-level aerobatic pilots.
What do you consider old?
I'll be 80 in October and I am still alive.
( I was 70 when I flew in my last airshow, I retired because I was tired of all the B.S. that was part of the airshow business. Not because I was not up to standards.)
But everything is getting strangled by rules and regulations and moderation in today's society.
