 Lieutenant Smith and Lieutenant John P. Richter were the pioneers in establishing the practicability in refueling airplanes while in flight, and on 28–29 June 1923, they piloted an airplane refueled in flight for 37 hours, 15 minutes and 14 and a half seconds, breaking the endurance record, the speed records from 2,500 to 5,000 kilometers, and the distance record (5,300 kilometers).By their endurance, resourcefulness, and determination they reflected great credit upon themselves and the Army of the United States.
