The internet is an amazing thing. For example, I stumbled across the Official Site of the Chickasaw nation (a Native American people of the United States, originally from present-day Mississippi, now mostly living in Oklahoma) and found their first aviatrix was Pearl Carter Scott. She got her pilot's license at the age of 13! And believe it or not, this was back in the year 1928 -- almost 80 years ago.

So you see, women have been pilots for a long, long time. Women of all races and tribes, too! Read more at: http://www.chickasaw.net/heritage/250_1056.htm

She was a student of Wiley Post (a famous pilot from the early 1900s and supporter of women pilots), so you can see that website, www.wileypost.org for more info.
