I know this is pretty late, but I have most of the components of this game, all except one of the baloon maneuver cards. Tell me what you need.
I appreciate the reply, but back in 2005 someone sent me copies of the cards needed to play, in exchange for copies of the cards he was missing.
I uploaded scans of all the cards to BoardGameGeek, and now you can find them in the "Files" section of the Ace of Aces: Balloon Buster page. I just reviewed them, and I saw that there doesn't seem to be any balloon maneuver cards, though. (You can upload them here for GeekGold, if you're up to it.)
Thanks again for the reply, John.
