During the darkest days of World War II, as bombs fell on the home population of Great Britain and the firestorm that had raged across Europe was poised to engulf the world, there were precious few ways for the Allies to strike back at their enemy. One of their most powerful weapons was the magnificent Avro Lancaster bomber, with its legendary Rolls-Royce Merlin engines, its enormous bomb bay, and its steadily improving electronic countermeasures that enabled it to strike deep into the heart of Nazi Germany. With wonderfully detailed photographs of various crew positions, instrumentation, engines, and armament, along with archival WWII photographs, you'll fly with the pilots and crews of this aviation classic.
