10. Fly Girls

During WWII, more than a thousand women signed up to fly with the U.S. military. Wives, mothers, actresses and debutantes who joined the Women Airforce Service Pilots (WASPS) test-piloted aircraft, ferried planes and logged 60 million miles in the air. Thirty-eight women died in service. But the opportunity to play a critical role in the war effort was abruptly canceled by politics and resentment, and it would be 30 years before women would again break the sex barrier in the skies.
