When did Amelia Earhart receive her distinguished flying cross?

The Air Force was then part of the Army, as the still-used theme song makes clear. Amelia was in neither service. She did receive the Distinguished Flying Cross for her services to aviation. As far as is known this was the first feminine award, and the first and only one to a Civilian airman- as it was later restricted to the military. Today there is both a Distinguished Flying Cross AND an Air Force Cross- two different medals. There is also the Distinguished Service Cross which sometimes has been awarded to, say Defense contractors who are, again, not in the AF Blue or Army Olive Green!.
