It's a pity you're only in Transit Rory and not abe to stay at least a day. A couple of years ago, my wife and I were off to a conference in Prague when we decided to go a couple of days early and went down to Sinsheim from Frankfurt to the Museum there for the day. (It took a couple of trains conecting through Heidleburg)
We got to see and go aboard a Concorde and the Russian Tupolev "Concordski" as well. Both on display with a bunch of other stuff Aviation and non Aviation. Well worth it for sure.
