Wheeler Army Airfield the first transpacific flight from California in 1927; the great Dole Air Race from California to Hawaii; the first transpacific flight from the U.S. to Australia in 1928, and the first Hawaii-to-Mainland solo flight in 1935 by Amelia Earhart. Ms. Earhart visited Wheeler Field in 1935 in her Lockheed Vega and in 1937 in her Lockheed Model 10 Electra. Kingsford Smith, in his plane, the "Southern Cross", also used the airfield on his historic flights across the Pacific. By 1940, Wheeler Field had evolved into a primary base for Army Air Corps pursuit (i.e., "fighter") aircraft such as the P-40
Amelia Earhart the RDF equipment during the world flight. During the transatlantic leg of the flight (Brazil to Africa), the RDF equipment did not work. The radio direction finding station at Darwin expected to be in contact with Earhart when she arrived there, but Earhart stated that the RDF was not functioning; the problem was a blown fuse. During a test flight at Lae, Earhart could hear radio signals, but she failed to obtain an RDF bearing. While apparently near Howland Island, Earhart reported receiving a 7500 kHz signal from "Itasca", but she was unable to obtain an RDF bearing. The antennas
