Fly Girls is an informative and engrossing account of women pilots in 1920s and '30s. O'Brien focuses on five women with stories screaming to be remembered. They faced incredible obstacles and prejudices as they flew in races and other events. Hostility was evident with remarks such as "flying saved her from becoming a nice old maid."

Fly Girls launches us into a period of aviation history largely forgotten. I applaud Mr O'Brien for bringing these Five to life!
