Rare Aerial Footage of World War I Shows War-torn Battlefields in 1919

Extraordinary pictures of the aftermath of World War I, which have been hidden away for nearly a century, have been discovered in a vault in Paris in 2010.

The footage was filmed from a camera strapped to a airship by a French pilot Jacques Trollie de Prevo overflying the battlefields of France in summer 1919, following the route of the Western Front and capturing the devastation in amazingly graphic detail.
