With regard to this accident I made this comment in my first post.
In Europe we had a 200 foot floor at all airshows that was very strictly enforced , had there been the same 200 foot floor limit at the airshow in which this pilot died he would still be alive.
Had such a restriction been in place we would not be having this conversation. ( Assuming he did not have a heart attack or a stroke. )
We can not control aging, we can control safety to some extent.
