For a start, I don't think it is a great interview question. The whole interview should be a guage on your motavation and if you're just after the cash and a few gold bars, it will soon show.
Having said that, I don't think your answer would impress me. The only time I've been asked something similar was at OASC in the early 90's. Once they got me talking about aeroplanes in general and the air force in particular, it was pretty much '...OK, we get the message, you can stop now.' If you're motivated to fly, it will soon come across.
