Step-by-step explanation:
The primary motivation for establishing a training program for women pilots during World War II, as implied by the author, was the shortage of qualified male pilots. The Women's Flying Training Detachment, conceived by Jacqueline Cochran, aimed to train women to ferry military aircraft due to the pressing need for male pilots in combat. Although it was a significant step towards gender equality and broadening women's roles, the immediate goal was to address the practical necessity for pilots to transport aircraft, underscoring women's critical supportive role in the war effort.
