Britain From Above

In East Anglia, Andrew Marr flies 10,000 feet above ground to locate a patchwork quilt of fields that produce a quarter of the country's wheat and barley. He also investigates how farmers are using military-style spy planes and GPS technology to monitor their crops, and faces his biggest challenge yet - a daunting plummet from an airborne plane in his first ever skydive.

In the heat of World War Two, 300,000 "unproductive" farms were commandeered by the government and tightly regimented to increase their output.

Andrew Marr concludes his journey as he microlights and paraglides through the skies, getting a buzzard's eye view of the nation's untamed and untameable landscape. Along the way, he joins geologists, meteorologists, amateur photographers and festival goers to explore Britain's geology, the impact of the weather on our shores and the riches hidden beneath our feet.

This final episode tells the story of how Britain's industrial heartlands have been transformed in the space of a single lifetime.
