I have to kinda agree... 70+ year old people should not be pulling Gs near crowds.
I don't think you understand the situation. His age has
NO RELEVANCE whatsoever to this accident, it was a mechanical failure, leading to 10+ Gs and unconsciousness. As I already pointed out this guy

at 41 suffered G-LOC and didn't wake up till he was at 9,000 ft from the same failure. If you where in his seat you'd have been out like a light as well. I'd wager that Jimmy at 74 was in a lot better shape then many pilots are at 40, 50 or 60.
On what ground would you deny him the opportunity to fly? What medical condition does he have that would preclude it? I'll tell you what, NONE. Because if he did, he would not have passed his last medical and his license would be yanked.
