'Never has so much been owed by so many, to so few.' This is the story of those few, in their own words.

In the summer of 1940, the British frontlines were the skies above southern England. Spitfires and Hurricanes took on the might of the Luftwaffe, and its feared Messerschmitt fighters, dogfighting high above civilians watching on in awe.

Hitler was determined to invade Britain and close down the Western Front for good. But his plan – Operation Sea Lion – could not begin while the RAF could still harry an invasion fleet. It had to be broken.

Up to five times a day, the pilots of RAF Fighter Command scrambled to meet the inbound Luftwaffe. At one point, every available British fighter plane was airborne – Britain threw literally everything into the fight, and was tested to the very limits. Against all odds 'The Few', as they came to be known, bought Britain's freedom – many with their lives.

These are the personal accounts of the pilots who fought and survived that battle. We will not see their like again.
