Satellite View

This Clip takes 2 minutes to is amazing to watch the heavy air traffic lanes change over a period of 24 hours – also amazing that there aren’t more collisions.


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.

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.

Thanks Barry & Louise D.
