This is a 24 hour observation of all of the large aircraft flights in the world,
condensed down to 1:11. From space we look like a bee hive
of activity. 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 aeroplanes 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.
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 ever
seen. It surpasses the "World At Night" poster that NatGeo (I think)
published bout 20 years ago. This highlights where civilization is
located on our planet.
You can tell it was spring time in the north by the sun's footprint
over the planet. You could see that it didn't set for long 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
how we 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.....
