If this is 24-hours of air traffic, I can't imagine how much jet fuel and other substances we are injesting daily, and it should not be hard to fathom how years of this could affect climate change. Just sayin'.
It is a 24 hour observation of all of the large aircraft flights in the world, condensed down to about 2 minutes.
From space they look like bees, but the yellow dots are the airplanes in the sky during a 24 hour period.
You will see the light of the day moving from the east to the west, as the Earth spins on its axis. Note how the flow drops at night in Europe and NA.
And see the aircraft flow of traffic leaving the North American continent and traveling at night to arrive in Europe in the morning. Then you will see the flow changing, leaving Europe in the morning and flying to the American continent
And watch the North America traffic move from East to West as the sun comes up.
Ever wonder why Air Traffic Controllers get headaches ???
