Harrison Ford, while older, definitely had an impact on kids.
One morning during OSH '04 (?), when my son was about 13 years old, we decided to catch breakfast at the Hilton before heading into the show. (For those unfamiliar, the Hilton adjoins the North 40 aircraft camping area, and offers respite from the heat and a decent breakfast buffet.)
We were seated, got our drinks -- and then noticed that Harrison Ford, his wife Callista Flockhart, and their young son were seated at the next table.
My son almost died on the spot. THERE was Han Solo, right freaking THERE! AND Indiana Jones!
I was proud to be an EAAer that day. No one hassled them for an autograph until the very end, when they were done eating and some guy just couldn't contain himself anymore.
Bottom line: Harrison Ford still had "street cred" with kids.
But I hear you about getting a young, relevant Hollywood personality to be chairman. Sean Tucker is awesome, but almost completely unknown, outside of the airshow world.
