D-Day in 3D (2013x11)

:

Discover new secrets behind “D-Day” - the day that changed the course of the 20th Century. On June 6, 1944, the Allies’ invasion of Nazi-occupied France transformed the outcome of World War II; however, did you know “3D” photography was the key to “D-Day’s” success? This futuristic technology mapped every inch of the Nazi defenses, allowing the Allies to execute the greatest invasion in history. The U.S., along with its British and Canadian allies, faced a major challenge - the Nazis heavily fortified the entire Northern European coastline with numerous trenches, bunkers and high-powered weapons. The Allies had to find a weakness. They came up with a creative solution — 3D aerial photography. Spy planes carried two synchronized cameras, taking side-by-side photographs, which were then combined to create a three-dimensional map of the Nazi defenses. After two years of collecting data, these 3D photos showed the Allies that Normandy was the best place to take down the Nazis. The 3D photos helped the Allies create daring missions and overcome the “devil’s garden” – full of landmines, blockades and steel fences – on the beaches of Normandy.
