NOVA - Nazi Attack On America

Tuesday, July 26 at 7 p.m.

Famed undersea explorer Bob Ballard investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub's sinking.
