flight over Greenland with fantastic scenes of ice, glaciers and icebergs. This inspired me for this month's gallery with aerial photographs. I took these mostly on board of airplanes but some were taken from visitor floors of high skyscrapers. It's often not easy to take photos in the air, because either the airplane windows are dirty or damaged or the air is misty. But it is always an amazing sight to see the earth from high above in the sky. Do you know, what cities or areas are shown in today's photos?
