Before the 70th anniversary of the D-Day landings last week, PBS' Nova aired an episode called "D-Day's Sunken Secrets," featuring a striking simulation of the landing harbor in a newly-imagined digital rendering.

The two-hour show also examines the undersea archaeology of sunken ships and tanks.

On June 6, 1944, 200,000 Allied troops landed on the beaches at Normandy, France, and began the liberation of Nazi-occupied Europe.

On June 6, 2014, world leaders honored veterans and the fallen at ceremonies in France and around the world.
