WWII: Secrets from Above

As we fly above the infamous battle sites of D-Day and Dunkirk, soar over hidden Nazi bunkers, and glide across lost battleships and sunken shipwrecks – this new series exposes secrets of World War Two - in a brand-new way. Through a unique aerial perspective – with exclusive access to key locations today and by matching them to historic aerial archive imagery - we will ‘fly back in time’ to recount daring raids and deadly battles in a way that has never been seen before.
