Overview: The B-17 Flying Fortress, a term coined by a Seattle Daily Times report in 1935, was a quantum leap in offensive air power. Designed for a nation whose foreign policy was still deeply isolationist, and an Air Corps whose in-service bomber fleet was dominated by bi-planes, the B-17, with its four engines, huge wingspan, enviable payload – almost double that of contemporary bombers – and all metal construction, ushered in a new age. For an aircraft of its size and relative complexity the B-17’s design and development was heralded by a host of key innovations with the unveiling of the XB-15 (Boeing 294), including engine access crawl ways, enhanced endurance and massive load capacity. Within a year the Y1B-17 or Model 299 had refined ideas from the XB-15 and produced a sleek, attractive-looking aircraft. By 1937 all testing had been completed and the first 12 aircraft were delivered to 2nd Bombardment Group for assessment.
