I came across a beautiful video which has captured and condensed 24 hours of global air traffic in just 2 minutes !
The yellow dots are aircrafts. Note that as evening approaches, the traffic is predominantly from the US to Europe (Eastbound) and when daylight comes, the traffic switches and it is predominantly from Europe to the US (Westbound).
Have you also noticed how less is traffic movement over deserts of Africa or even in parts of southern America ?
This is all from here.
Have a happy weekend ! Bon weekend !
