From space it looks like a bee hive of activity. With this 24-hour observation of aircraft travel on the earth's surface we get to see the daylight pattern change across the planet as the "day" progresses (and by noting where the 'sun is shining' in the northern hemisphere, across the top of the 'movie', you can estimate the time of day). The video starts at about 9PM Eastern Daylight time on the east coast of the USA and stops 24 hours later.
Each yellow dot is a plane in the air. Watch the concentration of the dots change as daylight comes and goes. You can tell where the world's wealth is located (and not located) by the concentration of planes over North America, Europe, and the eastern edge of Asia. Enjoy this unique view from outer space.
