This simulation by Zurich University of Applied Sciences - or simply Zhaw - shows the commercial flights of the world, seen over 24 hours. You can see how flights leave America as morning is coming to Europe and how Europe then becomes the center of air travel during the European daytime hours, and then it shifts right back again as the night falls over the EU. This shows quite clearly how we're becoming less of a bunch of countries and more of a global community, which is kinda cool.
