those landscapes are magnificent, and I bet it must have been even nicer doing it in a pair of gliders. Your shot with the other glider ahead of you is awesome.
+1 on that as well - that should be researched and sold to 1) the glider company, 2) the company that rents glider time, 3) the airport from which it came, 4) the dept. of tourism... But I bet you've already thought of that and already have phone calls in to the appropriate offices. (or will once you are done with your vacation)
