World airline traffic over 24 hours

This remarkable animation shows airline flights around the world over a 24-hour period. It's very interesting to see how flights are timed to take advantage of dark periods for east-west travel, arriving at the beginning of the business day. I recommend watching in full-screen mode for the best perspective.

Having flown over many of the routes shown, it's amazing to see how many other planes were going in the same direction at the same time!
