A feature documentary about the people and the planes that helped win World War War II. Through people personally connected to the events, the film investigates the story of how the Spitfire, its stable-mate, the Hawker Hurricane and its great adversary, the Messerschmitt 109 came into being during the huge advances in aviation in the interwar period—and then how the pilots fared in combat, three miles up in the skies over Europe, Africa and Asia.

To celebrate the centenary of the Royal Air Force, Ewan and Colin McGregor take to the skies in some of the world's most iconic planes. These are the planes that were involved in aerial combat at every stage of the RAF's story, from the biplanes used in the early days of dogfighting in World War I to the beautiful Spitfire of the Battle of Britain, the plucky Lysander and on to mighty Vulcan nuclear bomber, as well as the Chinook helicopter and supersonic Typhoon that are still in service today. 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. On their journey Ewan and Colin meet an amazing cast of characters.

As 40 Spitfires and Hurricanes assemble for a unique flypast marking the 75th anniversary of Battle of Britain Day, two special programmes commemorate the heroes Churchill famously called 'The Few'.

'Spitfire Sisters' tells the story of the remarkable ladies who flew for the Air Transport Auxiliary (ATA) in World War Two. Called upon to ferry military planes of all types between airfields, factories and maintenance units, these ladies were faced with bad weather, operational adversities and flying planes they had never flown before. Now in their 90's, these ladies tell us of the adventures they experienced during their incredible lives as Ferry Pilots. With tales of love, laughter and loss, people can't help but feel permanently amazed by the achievements of these unique women. They are the unsung heroes of the Second World War.
