Almost 60 years ago, I went to the show at Reading, PA.
I even went back a second time to show our airplane in the “Best Equipped” contest.
I decided that it was not worth the risk and never went back and have never attended another airshow since..
I should have added that there was so much going on and so many aircraft in mothion and in flight at the same time that it was extremely difficult to be aware of everything.
No matter how good the communications method, some things happen before you can take evasive action.
