On 12 August 1944 Joseph Kennedy Jr. - older brother of the famous John Kennedy - flew a liberator drone high up into the Norfolk skies as part of Operation Anvil. Their objective was to guide the aircraft towards a secret German V3 site at Mimoyecques in France. But things did not go according to plan: the drone exploded mid-air before Kennedy or his co-pilot could escape the craft, killing both. In this documentary, Drones historian James Rogers explores the story behind Operation Anvil and the fateful final flight of a man who was meant to be the President of the United States.
