The publicity for the first successful transpacific flights from Oakland to Hawaii were stolen by two flights in June and July 1927, ahead of the scheduled August start for the Dole Derby. On 28 June, about a month after Dole posted the prizes, Air Corps Lieutenants Lester J. Maitland and Albert F. Hegenberger flew a three-engine Atlantic-Fokker C-2 military aircraft from Oakland Municipal Airport to Wheeler Army Airfield on Oahu in 25 hours and 50 minutes. An earlier attempt in 1925 had ended in failure for two Navy PN-9 seaplanes; one of the aircraft, commanded by Commander John Rodgers, ran out of fuel several hundred miles short of Hawaii and sailed to Kauai over the next nine days.
