East Coast

Arthur's final airborne journey covers the epicentre of Britain's wartime avaiation effort - the east coast. He visits four airfields that played a role in world War Two, but have completely changed since. First up is Lincolnshire, which once boasted 46 military airfields. Only five remain today. At East Kirkby, a local family have bought and preserved part of the former airbase as a memorial. Flying over East Anglia, Arthur has an overview of the staggering scale of the wartime 'friendly invasion' by tens of thousands of American servicemen. At RAF Lakenheath, he sees the US Air Force's awesome F15 fighter. At Cranwell, he visits the world's oldest and grandest air academy and home to the only aerobatic team in the world licensed to take passengers - and there's no way Arthur's leaving without hitching a ride.
