This is a neat map making the rounds on the Internet that shows air travel routes across the globe during the course of a day. I am calling it a companion to a post from about a year ago showing something similar for US air travel.
On the evening of the Thanksgiving holiday, here is a gorgeous visualization of air travel across the US, compiled by a graphic artist named Aaron Koblin. I’m a sucker for stuff like this. The static views are beautiful, but the time lapse version is mesmerizing.
