Extraordinary aerial pictures of First World War battlefields have been discovered, after being hidden for nearly a century.
The dramatic aerial shots show the huge damage wreaked on towns such as Ypres and Passchendaele. The programme, on BBC One this Sunday evening, also includes aerial footage taken by British pilots. These new images give historians of the First World War a new insight into the impact of the fighting on the western front.
‘The First World War from Above’ is on BBC One on Sunday at 9pm.
