Betty Gillies was an American aviator, and the first pilot to qualify for the Women's Auxiliary Ferrying Squadron, later amalgamated into the Women Airforce Service Pilots.

The Women Airforce Service Pilots (WASP) was a civilian women pilots' organization, whose members were United States federal civil service employees. Members of WASP became trained pilots who tested aircraft, ferried aircraft and trained other pilots. Their purpose was to free male pilots for combat roles during World War II. Despite various members of the armed forces being involved in the creation of the program, the WASP and its members had no military standing.
