The town of Bodenwerder, on the River Weser, in Germany is the birthplace of Baron von Münchausen. Part of the legend has him accidentally being shot from a mortar and riding through the air on a cannonball.
When I was stationed in Germany in the 70's they used to have an annual lights/water/music festival. Part of the festival was a re-enactment of that cannonball ride. And no, it's not a dummy.
