I was emailed this link, and thought that it might be of interest. It shows world air traffic (big jets only) over a 24 hour period compressed into 80 seconds. Really brings home the amount of major air traffic there is these days. Fascinating and, frankly, depressing too.

"All the yellow dots are planes !! UNREAL

READ THIS BEFORE VIEWING THE VIDEO

This is worth watching for just a few minutes. Stay with the photo for a while.

This is something that everyone should see. For us old-timers it is really fascinating. For our children/ grandchildren it provides a superb learning moment and an opportunity to open up what could be a very interesting discussion. This is one of the coolest things I have ever seen. It surpasses the "World At Night" poster that NatGeo (I think) published about 20 years ago and my "America At Night" coffee mug. How many people do YOU think are in the sky at any given moment?

What you will see, is a video showing air traffic around the world for 24 hours, taken from a satellite.

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 it's 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. Remember watch the day to night ...

Day is over in Australia when it starts."

Enjoy ;{
