 A fifth of the bombloads did hit the Schneider works, but residential areas were also heavily damaged.At its north-west end, Lake Constance is divided in two by a ten-mile spit of land with the German city of Konstanz at the tip, providing a good pinpoint.From Konstanz, Friedrichshafen lies 15 miles due east across the water; it is set in a bay, and the bombers’ track would take them directly over the near headland of the bay after 8 miles.
