World Air Traffic one minute video

This is a fascinating one-minute video...
It is a 24-hour observation of all of the large aircraft flights in the world (recorded by the airplane flight transponders via Geo-stationary orbital satellites) patched together and condensed to about a minute, i.e., you watch 24 hours of flights compressed into one minute.
You can see it is summer in the north by the location of sunlight on the planet.
With this 24-hour observation of aircraft travel on the earth's surface, we also get to see the daylight pattern move across the planet.
Notice the reduction of activity in each region during the darkness of late night/early morning.
