WORLD AIR TRAFFIC 0-24 HRS..VIEW FROM SATELLITE
.
The yellow dots are airplanes In the sky during a 24 hour period.
.
Stay with the picture. You will see the light of the day moving from the east to the west, as the
Earth spins on its axis.
.
Also you will see the aircraft flow of traffic leaving the North American continent and travelling at night to arrive in EUROPE in the morning. Then you will see the flow changing, leaving
the UK in the morning and flying to the American continent in daylight.

.
It is a 24 hour observation of all of the large aircraft flights in the world, condensed down to
about 2 minutes. From space we look like a bee hive of activity.
.
You could tell it was summer time in the north by the sun's foot print over the planet.
.
You can see that it didn't quite set in the extreme 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 and have had to imagine just what is going on.
.
With this 24 hour observation of aircraft travel on the earth's surface we get to see the daylight pattern move as well.
