 She also trained male air and infantry gunners at Las Vegas Army Airfield during the early 1940s.

Maggie Gee (August 5, 1923 in Berkeley, California – February 1, 2013) was an American aviator who served in the Women Airforce Service Pilots (WASP) in World War II.
 She was one of two Chinese American women to serve in the organization, the other being Hazel Ying Lee.

The Women Airforce Service Pilots (WASP), called "Women's Army Service Pilots" by some sources, was a paramilitary aviation organization.
 The WASP's predecessors, the Women's Flying Training Detachment (WFTD) and the Women's Auxiliary Ferrying Squadron (WAFS) organized separately in September 1942.
 They were the pioneering organizations of civilian female pilots, employed to fly military aircraft under the direction of the United States Army Air Forces during World War II.
 The WFTD and WAFS were merged on August 5, 1943, to create the paramilitary WASP organization.
 The female pilots of the WASP ended up numbering 1,074, each freeing a male pilot for combat service and duties.
 They flew over 60 million miles in every type of military aircraft.
 The WASP was granted veteran status in 1977, and given the Congressional Gold Medal in 2009.
The Women's Flying Training Detachment was a group of women pilots during World War II.
 Their main job was to take over male pilot's jobs, such as ferrying planes from factories to United States Army Air Force installations, in order to free male pilots to fight overseas.
 They later merged with the Women Airforce Ferrying Squadron (formerly the Women's Auxiliary Ferrying Squadron) to form the Women Airforce Service Pilots.

The Women Airforce Service Pilots Badge is an award of the United States Army that was issued during the Second World War.
 The badge created for the Women Airforce Service Pilots, or WASP (not WASPs, because the acronym already includes the plural "Pilots"), was awarded to more than a thousand women who had qualified for employment as civilian, non-combat pilots of military aircraft used by the U.S. Army Air Forces during World War II.
 The first wings were privately and hastily designed and paid for out of the pockets of Floyd Odlum and his wife, Jacqueline Cochran, who in 1942 became the head of WASP.

Question: In which year, did Floyd Odlum's wife who became the head of the Women Airforce Service Pilots (WASP) pass away?
