A long day in the middle of a Viking river cruise. It started with a longer-than-planned bus ride to the day's city, and ended with a longish ride back. And then, just before we got to the dock, we caught a brief glimpse of what looked like a 747 grazing the roof of a building!
And then it was out of sight, and none of us were sure what we had seen.
But a bit of internet research turned up the Auto and Technik Museum in Speyer, which hosts the huge walk-in exhibit of a retired Lufthansa 747. Sadly, it was too late for us to be among the half-million who visit it every year and get to walk through not only the 747 but also a German submarine, a Russian Antonov AN22, locomotives and a houseboat.
