The Douglas C-47 Skytrain and its near twin, the C-53 Skytrooper, formed the backbone of American airborne transport during WWII. In addition to hauling cargo, these aircraft also delivered paratroopers to the front, including for the Normandy invasion. Derived from the Douglas DC-3, the C-47 saw service with US and Allied militaries in Korea and even Vietnam, including notably the heavily armed AC-47D gunship. This volume explores the development and use of the aircraft, as well as details of its construction. The Skytrain was indispensable to the American war effort; more than 10,000 were built and many are still flying today. The planes are also on display at museums on every continent aside from Antarctica, making the plan very relatable and accessible for readers all over the world. Readers will enjoy nearly 300 images of the C-47 and its variants, including the C-53 and AC-47D.
