NOVA: 3D Spies of WWII - Destroying Hitler's Top Secret Rockets

This installment of NOVA examines the WWII Allied initiative to locate Nazi rocket bases. The program brought together experts from British universities and Hollywood to study 3-D stereoscopic photos of German territory that had been shot by specially converted Spitfires. The result: Allied bombing raids that set back the German rocket program and helped ensure the success of the D-Day landings. The episode includes 3-D graphics that recreate what the photo spies saw.
