World Air Traffic 24 Hour Period

This e-mail (pasted below) was forwarded to me, along with a video. Rather than post the video, I found a YouTube link:

Here is the text of the e-mail, presented in unedited form:

Amazing and interesting.....!

What you will see in the attached movie clip is the air traffic around the world over a period of 24 hours taken from a satellite.

It is a 24 hour observation of all of the large aircraft flights in the world, condensed down to just over a minute. From space we look like a bee hive of activity.

I'm sure that you won't believe this at first!!!

The yellow dots are airplanes in the sky during a 24 hour period. Stay with the picture or watch it over again, and notice the following:
→ See the light of the day moving from the east to the west, as the Earth spins on its axis.
→ See the flow of aircraft traffic leaving the North American continent and traveling at night to arrive in the UK in the morning.
→ Then see the flow changing, leaving the UK in the morning and flying to the American continent in daylight.
→ See if you realize that it was summer time in the north (by the sun's foot print over the planet).
→ See the daylight pattern moving across the earth's surface and that the sun didn't quite set in the extreme north and it didn't quite rise in the extreme south.

I have never seen anything as explanative as this before. We are taught about the earth's tilt, how it causes summer and winter, and also the movement of the daylight pattern. Until now we have had to just use our imagination to picture what is going on. With this 24 hour observation of aircraft travel on the earth's surface, we
get to see the above in actual action...

Remember to watch the day to night..... day is over in Australia when it starts.
