Final answer:
Bessie Coleman, a pioneering African American aviator, was denied entry into the Air Force despite already having a pilot's license. She faced racial discrimination and gender bias and taught herself French to earn her pilot's license overseas.
Step-by-step explanation:
The individual who, despite already having a pilot's license, was denied entry into the Air Force was Bessie Coleman. Bessie Coleman, a pioneering African American aviator in the early 20th century, faced racial discrimination and gender bias that prevented her from being accepted into American flight schools. As a result, she taught herself French and earned her pilot's license overseas. Her determination and skill paved the way for other African Americans in aviation.
