the first thing that came to my mind was cruise ships. That
sounds odd and I’ll explain. Most ships are built in Germany and Italy. They
are built in sections and welded together. As you walk down the passageway you
can see where the sections come together. If the passageway is level and
smooth, it was built in Germany. If you come along the passageway and you have
to take a step up where they meet, then that ship was built in Italy. The
collapse of the bridge does not surprise me.
