The most impressive military landing recorded in history: 160 thousand soldiers, 11 thousand planes and almost 7 thousand boats of all types. It's D-Day, the longest day. Thousands of young American, English and Canadian soldiers wrote one of the most important pages of the Second World War. While the pale light of dawn spread over the Channel, the largest amphibious invasion force ever assembled up to that moment lands on the coasts of Normandy: it is June 6, 1944. Alberto Angela from the places of the landing on the coasts of Normandy will reconstruct the crucial moments of the D-Day through exclusive testimonies of the last survivors.
