Of all the Allied bombers of WWII, the Douglas A-20 Havoc is probably the least well known, but was a major contributor to the air war effort, flying yeoman and unheralded missions not only for the USAAF, but also for the Royal Air Forces of Britain, South Africa, and Australia; the Vichy and Free French Air Forces; and most importantly for the Soviet Army and Navy Air Forces, where more A-20s flew than with the USAAF. This is the sixth in the "Ultimate Look" series and presents the same meticulous depth of research as the other books, using a multitude of original sources, technical manuals, and photographs. It includes an in-depth look into the history of the Douglas Company and its founder, Donald Douglas, and its legendary designer, Ed Heinemann. This book is truly the definitive look at the Havoc.
