I was watching the Tulsa air show back around the late 1980s or so. They were already flying F-16s if that helps date it.
The only person I could get to go with me was my daughter. After a long time we or more accurately, I got tired. We walked away from the crowd and sat down on some large pieces of concrete right close to a hot dog stand. We could still see the show just as well from there.
Anyway, while we were resting, several of the pilots drove up in a, yes, a Ford Thunderbird. To my surprise, they all ordered hot dogs and then drove out to where the F-16s were parked.
It really struck me that they could eat hot dogs just before flying.
The Thunderbirds Shows utilize the Local Thunderbird Car Collectors in most locations as far as I know.
