...and she says that she loves flying.
If only there was a girl like that in my hometown...
Anyway, follow what the guys have said above. Get to know her better; her thoughts, interests, etc. Just be yourself around her/over Yahoo Messenger & maybe she'll change her mind. Try to (maybe) find a time where you can hang out with her, like at a football game, the mall, or, as mentioned before, go spotting. Maybe bring aviation up sometimes when you talk to her, maybe give her a better "education" into our world or something.
