View of air traffic from space..


You  won't believe this.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  the UK 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 could see that it didn't quite set in the extreme north and it didn't quite rise in the  extreme south.
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.
