A study of 3,883 communities with airports around the world and their connections to the air transportation network revealed that Paris is the most central to the international network. The study also revealed that the most complex air route in the world is from Mount Pleasant in the Falkland Islands to Wasu, Papua New Guinea, which requires 15 separate flights. The study, published in today's Proceedings of the National Academy of Science was headed by an engineer, and sadly, not a geographer.
