As an aside, if anyone is going to Southern Germany, it's worth going to Technik Museum Speyer, where you can really go into the guts of the 747. They also have a Russian Buran space shuttle.
The next day you could go to Technik Museum Sinnsheim, which is about half an hour from Speyer, and has both a Concorde and a Tupolev Tu-144 (both of which you can go inside).
