Of all the chapters of the Second World War, none are as daring, nor as intriguing, as the Air War. In the skies over Europe, some of the most iconic aircraft to ever take flight, did battle in a life or death struggle for supremacy. Today most of these aircraft are gone, but at the Royal Air Force Museum in London, Mat Mclachlan received the rare opportunity to get up close to some of these planes that survive. In this documentary Mat is shown around by Kris Hendrix, a historian at the RAF Museum.
