I'm surprised that Lufthansa would just donate them such a complete looking aircraft though. Apparently the 747-200 was still in production until 1991, and Lufthansa donated it in early 2002. They were in regular passenger use until 2016 and there are still a handful being used as cargo jets - and Lufthansa had an air cargo subsidiary that used 747-200s at the time.
Well, now you've convinced me to go to the Technik Museum. The Henry Ford Museum was an institution of my childhood and one of the things everyone we knew enjoyed when they visited the area.
They have both the Concorde and the Concordski -- the Russian Tupolev 144.
In between those two is the Hockenheimring, with F1 will be in July this year, and the very pretty university town of Heidelberg.
