Air Traffic Worldwide movie
Very similar to the Flight Patterns video I posted back in October 2007, this is a video showing all commercial flight in the world over a 24-hour period. The previous video was only the U.S., but this one shows the entire world. It also shows the day/night areas and you can see the increase in air traffic as dawn rises around the world. Its from the Zhaw School of Engineering in Zurich.
