Lucky Lady II

Lucky Lady II is a United States Air Force Boeing B-50 Superfortress that became the first airplane to circle the world nonstop. Its 1949 journey, assisted by in-flight refueling, lasted 94 hours and 1 minute.

The Lucky Lady II was a B-50 of the 43rd Bombardment Group, equipped with 12 .50-caliber (12.7mm) machine guns. For its circumnavigation mission, a fuel tank was added in the bomb bay for extra range. The mission required a double crew with three pilots, under the command of Capt. James Gallagher. The crews rotated in shifts of four to six hours.

Bearing a total crew of 14, the aircraft started its round-the-world trip at 12:21 p.m. on February 26, 1949. It took off from Carswell Air Force Base near Fort Worth, Texas, and headed east toward the Atlantic Ocean.

After flying 23,452 mi (37,742 km), the aircraft passed the control tower back at Carswell on March 2 at 10:22 am, marking the end of the circumnavigation, and landed there at 10:31 a.m. after having been in the air for 94 hours and one minute, landing two minutes before the estimated time of arrival calculated at take-off.

En route, the aircraft was refueled four times by KB-29M Superfortresses, near Lajes Air Base in the Azores, Dhahran Airfield in Saudi Arabia, Clark Air Base in the Philippines, and Hickam Air Force Base in Hawaii, using the soon-to-be obsolete grappled-line looped-hose technique. Following the refueling near Luzon, Philippines, the refueling tanker encountered poor weather conditions and crashed on March 1, 1949, killing all nine crew aboard; the accident report was altered to state the tanker was on a routine training mission to keep the accident from casting a bad light on the Lucky Lady II's successful circumnavigation.

The aircraft flew at altitudes between 10,000 to 20,000 ft (3,000 to 6,100 m) and completed the trip around the world at an average ground speed of 249 mph (401 km/h; 216 kn).

General Curtis LeMay, Strategic Air Command's commanding general, was on hand to greet Lucky Lady II upon its arrival, together with dignitaries including Secretary of the Air Force W. Stuart Symington, Air Force Chief of Staff General Hoyt S. Vandenberg, and Major General Roger M. Ramey, commanding general of the Eighth Air Force. LeMay said the mission showed that the Air Force could send bombers from the United States to "any place in the world that required the atomic bomb". He also said mid-air refueling could also be used for fighter aircraft. Symington noted that aerial refueling would "turn medium bombers into inter-continental bombers".

The aircraft's crew were each awarded the Distinguished Flying Cross and were honored by the National Aeronautic Association with its annual Mackay Trophy, recognizing the outstanding flight of the year and by the Air Force Association with its Air Age Trophy.
