The first nonstop around-the-world flight was accomplished by B-50A-5-BO (S/N 46-010) "Lucky Lady II" assigned to the 43rd Bomb Group. The flight which lasted from Feb. 26 to March 2, 1949, took 94 hours, 1 minute to complete. About two-thirds of the B-50As were modified as receiver aircraft for an in-flight refueling technique developed by the British. The fuel delivery aircraft (KB-29M) would fly above and forward of the receiver aircraft (B-50A) and unreel a long refueling hose. The crew of the B-50A would extend an apparatus from the rear of the aircraft designed to snag the refueling hose trailing behind the KB-50M. Once the fuel hose was captured, it was reeled into the B-50A where the crew connected it to the refueling manifold. Once the fuel transfer was complete, the hose was released and the KB-29M reeled in back. The "Lucky Lady II" flew a route covering 23,452 miles and required numerous in-flight refuelings. The 43rd Air Refueling Squadron supplied four pairs of KB-29M tankers for refueling, making it possible for the "Lucky Lady II" to complete the round-the-world flight nonstop. Although this early type of in-flight refueling was quickly replaced by more efficient methods, the around-the-world flight was proof that the USAF was capable of projecting air power anywhere in the world. The Cold War had started and the United States, Great Britain and France were in the middle of the Berlin Airlift, which started in June 1948 and lasted until September 1949. The significance of that fact was not lost on the media. The Associated Press noted that potential enemies "may reason that no single one of their cities, should war come, would be safe."The message was underscored less than eight years later when three SAC B-52s retraced the route of Lucky Lady II in less than half the time, making a simulated bomb run en route.It was not until 1986, however, that an ultralight airplane named Voyager circled the Earth nonstop without refueling. Flown by Richard G. Rutan and Jeana L. Yeager, it was made of plastic and paper and carried more than five times its own weight in fuel. That trip took nine days and, by then, astronauts were circling the Earth in 90 minutes and several had circumnavigated the moon.Today, the flight of Lucky Lady II is ancient history. Its commander retired from the Air Force as a colonel. SAC itself disappeared in an Air Force reorganization. The Lady herself was all but destroyed in an accident not long after the world flight. Her fuselage was salvaged and toured for a time as a recruiting exhibit before going on display at an air museum in Chino, Calif.
