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.

The Douglas World Cruiser (DWC) was developed to meet a requirement from the United States Army Air Service for an aircraft suitable for an attempt at the first flight around the world. The Douglas Aircraft Company responded with a modified variant of their DT torpedo bomber, the DWC.
