Discovery recalls the ‘longest day’

On the 67th anniversary of Operation Overlord, “Surviving D-Day” (8 p.m., Discovery) recalls the Allied invasion of the Normandy coast that changed the course of the World War II.

“D-Day” focuses on the American effort to secure Omaha beach and dissects the planning for the invasion in minute detail. We learn of strange new experimental weapons, like floating tanks, as well as old-combat standbys, including message-bearing pigeons. Like most war documentaries, “D-Day” puts great emphasis on strategy, deft leadership and individual bravery. But in our own age’s passion for forensic research, it also bores into the small facets of a soldier’s actions and explains how the fate of a man or a company of men may have hinged on the reading of a weather report, the shape of a belt buckle or the ingredients of their breakfast on the morning of June 6, 1944.
