Finding the Graf Zeppelin

Producer: Paul Russell Duration: 48:00 minutes

A Polish dive-boat leaves port toward the furthest reaches of the Baltic Sea. The divers aboard are about to undertake a rare exploration of Nazi Germany's most mysterious warship - the legendary Graf Zeppelin.

Today the Graf Zeppelin is the holy grail of shipwrecks for divers and naval researchers, but for 60 years the fate of the long-lost Nazi aircraft carrier was a mystery.
