Guy Martin looks at one of the most vital conflicts of World War Two and commemorates the many men and women who fought to defend Britain against the German air force in 1940. Tracing the story of the battle, Guy meets both veterans of the conflict and their descendants, pays tribute to the invaluable contribution of the Polish Air Force and Squadron 303, and investigates the pioneering work of plastic surgeons and air-sea rescue teams. Guy also gains a unique insight into a pilot’s experience by undergoing an intense flight training course and learning what it may have been like to take part in a ‘dogfight’ – an aerial duel between fighter aircraft conducted at close range.
