TTT - yes, it is. A wonderful tech museum in Sinsheim, Germany, with a twinned one a few miles away in Speyer. They have everything there - aircraft, cars, trains, boats from all countries. We'd been to the Speyer on and on the way back to the camp site saw what we thought were two concordes in the distance. We stopped the car, got the binoculars out and realised it was Concorde and Concordski; they really are remarkably similar. We worked out it was the Sinsheim museum and had no option but to go there. Well worth a visit (a full day each) if you happen to be in the area and certainly worth a look at their website.
