If you don't select a plane for her and hit cancel, she will default to an automatic choice.
I chose the German, and thought I could refrain from picking her plane, and it defaulted to the BF-110E.
So just a heads up pick it now or be forced to retrain her.
I don't like the fact that they forced you to pick one before it would release your hanger.
