I always enjoy reading the Disney Insider newsletter, and my favorite has always been the trivia question and answer column handled by Dave Smith, the Disney archivist. The one from the latest issue is particularly good, because I didn't know about such "hot air balloon" (Oh no, do I have to return my Disney fanatic membership card?)
The question was:
I know that Ear Force One is the name of Mickey's hot air balloon. What was the name of Donald Duck's balloon?
And the answer was:
It was known as Zip-A-Dee-Doo-Duck. It made its inaugural flight on November 20, 1987.
Sorry Mickey, but that name wins in my book! :)
