CAMBRIDGE, ENGLAND - MAY 10: Conservation Officers at the Imperial War Museum Duxford remove the fourth and final engine from the B-17 Flying Fortress Mary Alice in their American Air Museum on May 10, 2011 near Cambridge, England. The conservation team at the Imperial War Museum Duxford is embarking on a large-scale, 16 month project to dismantle and undertake conservation work on the B-17. The heavy bomber aircraft, which was capable of high-flying and long-range sorties, was introduced in 1938 and was instrumental in the American bombing campaign of World War II.
