To celebrate the Royal Air Force's centenary, Ewan and Colin McGregor fly the iconic planes and meet the people who made the RAF; from WW1 and the Battle of Britain to today's jets. The brothers experience aerial combat at every stage of the RAF's story, from the dawn of the dogfight in World War One, the triumph of the "The Few" and the bravery of the "Bomber Boys" in World War Two, through to the Cold War and right up to the supersonic jets of today. On the way they will meet some extraordinary men and women, they will explore the great moments such as The Battle of Britain and The Berlin Airlift, and will uncover little known stories of bravery and brilliance. It is a story of amazing machines and epic battles but above all it is the story of the men and women whose courage and ingenuity have been at the heart of the RAF for 100 years.
