Hi,Never been to this forum here before, so I am not sure whether this is old news. The following site has a nice video showing simulated air traffic across the US over a day. It's quite clear when it is day or night I guess:http://www.nasa.gov/vision/earth/improvingflight/index.htmlThen on the right hand side click below the"Day in the Life of Air Traffic over the United States. Animation of the air traffic over the US on a typical day."heading.Cheers,Siggy

Pretty Wild huh.

I love those kinds of displays.
