On June 27, Maitland and Hegenberger made the short hop from Crissy Field to the newly opened Oakland Municipal Airport, whose  runway was much preferable for the takeoff roll with full fuel load, and departed the next morning just after 7 a.m. for Wheeler Field, Oahu, with Maitland as pilot and Hegenberger as navigator. Although assisted as planned by the Signal Corps beacon on Maui, the directional radio receiver in the C-2 operated only intermittently before cutting out altogether.
