I've wanted an audio-version of this for driving packaged for driving cross country. With flying, the solution would need to account for which side of the plane you are on (and which direction). On the other hand, at 30,000 feet, GPS accuracy isn't all that critical. A couple of kilometers one way or another won't make much difference regarding what you can see. Not like the wing. Good luck.
