Watch Heroes of aviation online: Episode 4 B17 Lancaster

This documentary film tells the amazing story of America's B-17 the Flying Fortress and Britain's Lancaster Bomber, the most renowned bombers of World War II. The B-17's of the ‘Mighty Eighth’ with its robust unique design took the flight across Europe in broad daylight, at the expense of horrendous losses of men and aircraft. Star of the B-17 section was the Memphis Belle, the first UK-based B-17 to successfully complete 25 missions and return to the USA a true hero. The latter half of this moving and descriptive documentary traces the development of its British counterpart, the Lancaster, which is associated in our minds with the legendary raid on the Ruhr Dams by 617 squadron; otherwise know as the Dam Busters. Narrated by Edward Woodward
