Boeing B-17g Flying Fortress

Quad Piston

The Boeing B-17 Flying Fortress is the iconic four-engine heavy bomber that became the backbone of the United States Army Air Forces' daylight strategic bombing campaign over Europe during World War II. First flown in 1935 and entering service in 1938, the B-17 earned its legendary status through its ability to absorb tremendous battle damage and still bring crews home, thanks to its rugged construction and defensive armament of up to thirteen .50-caliber machine guns. More than 12,700 B-17s were built between 1936 and 1945, with the G-model representing the final and most produced variant. The Flying Fortress was designed around the then-revolutionary concept of high-altitude precision daylight bombing, operating at altitudes up to 35,000 feet where its turbocharged Wright R-1820 Cyclone engines could deliver maximum performance. With a maximum takeoff weight of 65,500 pounds and a range exceeding 2,000 miles with a 4,000-pound bomb load, the B-17 could strike deep into enemy territory. Its cruise speed of around 160 knots and maximum speed near 287 knots made it relatively fast for a heavy bomber of its era, though formations still required extensive fighter escort against Luftwaffe interceptors. Today fewer than 15 B-17s remain airworthy worldwide, preserved and operated by museums and warbird organizations as flying memorials to the 80,000 airmen of the Eighth Air Force who flew them in combat. These survivors appear at airshows and offer flight experiences, keeping alive the memory of the aircraft that helped turn the tide of the war. The B-17's distinctive profile—high-mounted wing, twin tail, and greenhouse nose—remains instantly recognizable eight decades after its combat debut. SkyMeter has tracked 15 flights across 2 airframes and 2 operators, with AMERICAN AIRPOWER HERITAGE FLY MUSEU the largest observed operator.
