S4E5: D-Day

In the three years leading up to D-Day, the Allies had assembled an array of weapons and transport vessels specially designed to overcome Hitler's defenses --  among them gliders, landing craft, minesweepers, and swimming tanks. This is the story of the maverick innovators who conceived of such an armory and its implementation into the largest amphibious invasion in the history of the world, and of the brave young men who woe;dd it so capably on the beach of Normandy.
