I think the static displays of military planes is good. Lot's of people and kids like to climb inside some of the large cargo planes,and of course the aircrews like to come to EAA.
I get very tired of the extreme noise of most of the jet acts. It hurts kids ears and often makes them scared to tears. Not the way to treat the public. If I am at a show where a F-35 is flying, I go inside or just leave the show, it is really obscene amount of noise and damaging to our hearing.
I sure don't want to spend the day at EAA where a large portion of it is subject to that kind of noise. A little modern jet flying goes a long way.

As for the warbirds, I love the great vintage prop planes. They represent the planes that helped win the war when the war was worth fighting. I have pushed for years to make one day, "modern day", and let the vintage jets and maybe T-28s fly that day. This is sort of done, but not followed strictly.
