The only flying B-29, Fifi, was at Dayton, and they were going to do a re-enactment of the dropping of the Atomic Bomb on Hiroshima, before the PC weenies started whining. But they decided that would be insensitive, so the Wall of Fire was scheduled to not coincide with the B-29 flyover.
The day I attended there was an accident early on, and the rest of the show was cancelled. Fortunately, we got to see Fifi arriving as we drove up.
Selfridge used to put on a great show with aircraft from the Confederate Air Force(Harlingen TX), lots of static displays, reenactments. Only El Toro had more.
...of course I've never been to Oshkosh...something I always wanted to do.
