On October 20, 1934 three-time Thompson Trophy air race winner, Roscoe Turner and his crew took off from the RAF Mildenhall in Suffolk England in the MacRobertson Trophy Air Race to the Flemington Racecourse in Melbourne Australia.

The race was sponsored by the MacRobertson Confectionary Company and organized by the Royal Aero Club. The rules were that there was no limit to the size of the aircraft or power, no limit to the crew size and no pilot could could join the crew once you left England. Three days' rations were needed for the crew along with safety equipment and efficient instruments. There would be prizes for the outright fastest aircraft and for the best performance on a handicap formula. The course needed to be completed within 16 days. The total distance was 11,323 miles.

The outright winner was a deHavilland Comet DH.88 from Britain with a time of 71 hours, 0 minutes. Second place overall and the performance winner went to a DC-2 flown by the Dutch KLM Airlines with a time of 90 hours, 13 minutes. Roscoe Turner's USA crew in a Boeing 247D was third overall with a time of 92 hours, 55 minutes.

Turner's Wasp engines on the 247D were christened by movie actree Bebe Daniels as “Nip” and “Tuck.” This engine is Tuck which accumulated more than 5,000 hours in commercial service before being retired in 1938.
