The third book in the series tells the amazing story of the most renowned bombers of World War II: America's B-17 - the "Flying Fortress" - and Britain's Lancaster Bomber. The B-17s of the "Mighty Eighth", with their unique, robust design, took flight across Europe in broad daylight, at the expense of horrific losses of men and aircraft. The 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 B-17's British counterpart, the Lancaster Bomber, is associated in our minds with the legendary raid on the Ruhr Dams by 617 squadron, known as the Dam Busters.
