I believe the one at Kermit Weeks' museum in Florida, which I've seen and walked through a couple of times in recent years, is the same one that flew in the UK in the early 1990s (including overhead my house in London - what a roar !). Kermit flew it himself over to his museum in Florida in 1995. I believe it participated in the opening ceremony of the 1996 Olympic games in Atlanta, but hasn't flown since.
It's a shame his museum is closing but whenever I've been there it only had a handful of visitors, and didn't seem to come anywhere near covering daily operating costs. It has a very nice café in the entrance lobby but when you are the only one sat in it you know it can't last.
