This is a pretty interesting map of air traffic patterns taken from space. I believe it only includes large jets though which may explain why some of the areas appear so neglected. The only relevance of this to the gym is that a lot of you are going away soon during the Olympics. If you are going to be away for more than a week let us know in advance and we can put your pass on hold.
Now watch it a second time and check out the relationship between the flights and the daylight moving from east to west.
