24 HOURS OF WORLD AIRCRAFT TRAFFIC — VIEW FROM SATELLITE. The yellow dots are aircraft in the sky during a 24 hour period.
Stay with the picture. You will see the light of day moving from the east to the west, as the Earth spins on its axis.
Also you will see the aircraft FLOW OF AIR TRAFFIC leaving the United States and traveling at night to arrive in Europe in the morning. Then you will see the flow changing, departing Europe in the morning and flying to the North American continent in daylight.
It is a 24 hour observation of all of the large aircraft flights in the world, condensed down to less than 2 minutes. From space we look like a beehive of activity.
You could tell it was summer time in the north by the sun's foot print over the planet. You could see that it didn't quite set in theextreme north and it didn't quite rise in the extreme south.
I have never seen this before. We are taught about the earth's tilt and how it causes summer and winter.
With this 24 hour observation of aircraft travel on the earth's surface we get to see the daylight pattern move as well.
