Answer:
The racial prejudice against blacks in America was so restrictive that blacks and women in general were not allowed to learn how to fly.
Coleman was a black woman who was interested in becoming a pilot but knowing the situation of things in America and also guided by her friend, Robert S. Abbott she decided to go to France to learn how to fly as the country was not as prejudiced as America if they were at all.
She realized she had no money and knowledge of the French language so she worked for 2 years as a manicurist and saved judiciously to go to France and learn how to fly an airplane. She would not have gone through the hassle of working and saving so hard and also learning a new language and going to a new country if her country was more liberal and less prejudiced.
