A picture over the Austrian-Alps taken from the air, on flight from Cologne to Tel-Aviv at an altitude of 33,000 ft.(approx. 10km).
The attached WS show same area without a zoom extract.
Location was about north of Lienz, Austria, assuming around Nationalpark Hohe-Tauern or the Grossglockner: 47.18, 12.7 on the map.
Took these photos 33 minutes after those Frankfurt pictures.
