Their Finest Hour DVD, History of Air Combat: The R.A.F. & The Battle Of Britain - Winston Churchill‘s ringing words are the enduring legacy of the brave pilots of the Royal Air Force who fought and won the Battle of Britain. Produced with the full support of the R.A.F., this DVD is the story of the pilots and the fighters who, in the summer of 1940, formed the thin line defending Britain from the planned Nazi invasion. Badly outnumbered, risking life and limb while the world held its breath, the British defied the might of the Luftwaffe. For the pilots and for the R.A.F., this truly was their finest hour.
