Britain From Above

From helicopters, planes, hang gliders and satellites, we see the picture of a nation constantly on the move with beautiful, varied and often mysterious landscapes. Swooping over towns and cities, allows Andrew Marr to see them from a new angle as he meets the people whose work takes them high above us to monitor and manage the networks that keep the country working.

Revealing the transformation of Britain's most important city: her capital, London. Starting with amazing Luftwaffe aerial photographs of the very first bombs of the Blitz falling on a vulnerable city, the programme tracks the changes that came out of five years of bombing. Comparing exhaustive footage of London in the 40s with the city of today, the team see how great plans for urban renewal were stillborn and, instead, London rebuilt itself in an ad hoc way along old street patterns. The only exception to this was the dramatic city that rose from the derelict docklands.

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.
