Could Guy Martin have been a fighter pilot in the Battle of Britain?
The 1940 conflict saw dashing Spitfire and Hurricane pilots outnumbered and outgunned by Nazi Germany's Luftwaffe. Yet these men, with an average age of just 20, inflicted Hitler's first defeat.
Guy will find out how by experiencing their same RAF training, from learning to fly in a Tiger Moth to performing high g-force combat manoeuvres at 200mph.
When Guy's instructor, vintage aircraft specialist Anna Walker, thinks he's good enough, he'll face every fighter pilot's toughest test: he'll fly a Hawker Hurricane head-to-head in a dogfight with a Messerschmitt 109.
