In the first episode of this landmark BBC Scotland series, presenter James Crawford discovers how the magical combination of powered flight and photography sparked a revolution that changed how we understood our world. Beginning with the story of aerial photography itself, James takes to the air to discover forgotten factories, abandoned villages and secret military installations. From the first pictures taken from World War One biplanes, to modern-day drones and helicopters, this is the story of how Scotland's countryside, communities and cities dramatically transformed in just 100 years.
