Andrew Marr 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.

Microlighting down the Great Glen Fault in the Scottish Highlands, Andrew learns about the very origins of the nation, where England and Scotland collided over 400 million years ago. In Northern Ireland, he discovers where geologists looked down from above at a river containing gold flowing through the Sperrin Mountains. While paragliding on the Welsh borders, he finds out how to read the clouds before flying over the east coast of Norfolk, where the wind's destructive powers are shown to devastating effect.

Geology and weather also affect the country's wildlife and satellite tracking demonstrates the migration of birds from Senegal and Siberia to Britain's shores. Using thermal imaging that is normally employed to search out insurgents in war zones, the shy Sika deer is tracked along the land on Lulworth Range.

He concludes his journey at the Glastonbury Festival, where for three days a miniature society flowers which is crowded, cheerful, dirty and mildly anarchic, and which has a transport system that only just works - features that sound vaguely familiar to Andrew. Show less
