The B-24 Liberator remains to this day the world's most-produced heavy bomber and multi-engine aircraft, and the most produced military aircraft in US history, with almost 19,000 examples leaving the assembly lines of five plants. Through a broad range of photos gathered from around the world, this book chronicles the design, development, and wartime use of the iconic early models of the B-24 -- those featuring the so-called "glass nose" -- from the assembly line to their use in the famous raid on the refineries at Ploesti, Romania, in 1943. The story of these iconic early WWII aircraft is told through carefully researched photos, many of which have never before been published, which are reproduced in remarkable clarity. Large clear photos, coupled with descriptive and informative captions, unlock the secrets of this aircraft.
