I cant see Baltra Airport in the Galapagos Islands (https://goo.gl/maps/x9PW5i4VWMH2) - it is "near" the most remote Mataveri Airport on Easter Island and may skew the most remote result to another airport?
I guess not all airports are included (e.g there is one I've flown into as a tourist to the antarctic peninsula that is missing (https://goo.gl/maps/u54LnTDYb8N2)
Great visualisation though :)
