This is the “Bodensee von oben” or Lake Constance from above with the Alps in the background. I love taking pictures from an airplane, even though you have a window in front of your lens and there are usually clouds or haze. The Bodensee, which borders Germany, Switzerland and Austria, is one of the cleanest and well kept lakes I’ve seen, despite the fact that boating is allowed. Rules and enforcement are very strict.
I love the Bodensee!
