The first aerial circumnavigation of the world was completed in 1924 by four aviators from an eight-man team of the United States Army Air Service, the precursor of the United States Air Force. The 175-day journey covered over 26,345 miles (42,398 km). The team generally traveled east to west, around the northern-Pacific Rim, through to South Asia and Europe and back to the United States. Airmen Lowell H. Smith and Leslie P. Arnold, and Erik H. Nelson and John Harding Jr. made the trip in two single-engined open-cockpit Douglas World Cruisers (DWC) configured as floatplanes for most of the journey. Four more flyers in two additional DWC began the journey but their aircraft crashed or were forced down. All airmen survived.

Lowell Herbert Smith was a pioneer American airman who piloted the first airplane to receive a complete mid-air refueling on June 27, 1923, and later set an endurance record of 37 hours on August 28, both in a De Havilland DH-4B. Smith also piloted the Douglas World Cruiser Chicago, which along with one other made the first aerial circumnavigation in 1924. Smith held 16 records for military aircraft in speed, endurance and distance. He was awarded the best achievement in flight Mackay Trophy twice.
