Last operational B-29 flies over Vance Published Sept. 25, 2014 By Staff Sgt. Nancy Falcon 71st FTW/PA VANCE AIR FORCE BASE, Okla -- The world's only operational B-29 Superfortress "Fifi" landed at Woodring Regional Airport, Enid, Oklahoma, Sept. 22 after performing a flyover at Vance. The B-29 is a four-engine propeller-driven heavy bomber that was used in combat during WWII and the Korean War. A B-29 came equipped with a fully pressurized cabin and remote-controlled machine gun turrets. It was designed as a high-altitude daytime bomber, capable of reaching about 40,000 feet, but was often used in low-altitude, night-time incendiary bombing missions. The most famous B-29 mission of all was the atomic bomb attacks on Hiroshima and Nagasaki during World War II. The B-29 fleet was retired in the 1960s. Most of them are used today as static displays. Fifi is owned by the Commemorative Air Force. This B-29 is to educate people about the history of the B-29s as it flies around the U.S. The aircraft is maintained by a volunteer force mostly comprised of veterans.
