This new book reveals rare original photos and full manufacturing details of America's greatest multi-engine combat aircraft flown in World War II. Contents cover building the Flying Fortress from wingtip to wingtip and from the bombardier's Perspex nose to the tail-gunner's twin-Browning cannons. Significant aspects of B-17 production include exterior views of each model variant from various angles, all crew stations in each B-17 type (including the entire flight deck), defensive gun turrets used in every B-17 model, fuselage interiors, exteriors, engines, nacelles, and even control surfaces. Factory-original color cutaway drawings as well as reproductions of original specifications sheets and other information-packed documents created by manufacturers during the 1940s are also included for the reader. As a research asset, the book's appendices feature a detailed survey of every production block of the 12,731 B-17 bombers produced during the war in an unbelievable time span of only three-and-a-half year--an industrial phenomenon unlike any the world had ever seen. What sets this book apart from all others in the crowded B-17 field is literally hundreds of factory-original close-up detailed photographs and illustrations accompanied by comprehensive high-resolution reproductions of original Boeing drawings, and all are explained in detailed yet easy to understand descriptive text. This book provides valuable data for the serious Boeing B-17 aficionado as well as a compelling story of America's aircraft manufacturing prowess for the dedicated aviation enthusiast.
