Andrew Marr goes on an epic journey through a day in the life of Britain, as seen from the skies. 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.
