Taking off from Carswell AFB in Texas, the B-50A, nicknamed Lucky Lady II and Commanded by Capt. James G. Gallagher with a crew of 14, the flight lasted 94 hours, 1 minute and covered a distance of 23,452 miles. To complete the flight, the Lucky Lady II was refueled in the air 4 times.

The Boeing B-50 Surperfortress was an updated B-29 that was given more powerful Pratt & Whitney R-4360 radial engines, a stronger structure and a larger rudder. The B-50 was the last piston-powered bomber Boeing built for the Air Force, and served for 20 years.
