Classics at Lake Constance

We travel to Friedrichshafen at Lake Constance in Germany, to visit the "Klassikwelt Bodensee" - a trade fair for fans of vintage planes, boats and automobiles. More than 300 exhibitors show off their rarities, including a British steamship from 1883. "On the ground, on the water and in the air" is its motto, and we met up with collectors from Austria and Liechtenstein.
