Two comments. 1) This appears to be only airports that offer commercial passenger service. 2) Easter Island has an airport! I was under the impression you could only get there by boat.

Hm, appears to be missing a lot of smaller airports in the USA. My home airport (E45) in particular. I'm guessing it's only using airports that have commercial air carrier service of some sort.

This runs slower on my computer than MGSV in ultra settings running on 4k resolution.

CPU bottleneck, not graphics card.

Of course. And JS is not a compiled language. And a language that was not created with performance in mind. I mean, I know this stuff, I can think of a lot of reason for it.

But the end result is just toooooooooo much for any reasons.

I thought that a voronoi partition is not possible with only straight lines on a non-euclidean space like that; this leaves me confused.

The edges are segments of great circles, which are the reasonable equivalent to a straight line on the surface of a sphere.

Or another way to look at it: if you model the earth as a perfect sphere, there's a one-to-one monotonic relationship between geodesic distance and distance in a straight line through the earth. Points that are equidistant by one metric are also equidistant by the other.

So you could get exactly the same diagram by finding the 3D Voronoi diagram of the airports as a collection of points in space, and then taking the intersection of that with the geoid.

Given the high cost of every pound when launching things into space this seems at first glance to be a pretty lousy idea. It seems to me solving this problem through diplomatic channels would be a much better plan given the fairly low probability of this event.

Neat, but it would be nice if it could zoom out a little more or adjust to the browser window size. I have 2560x1600 display split into four equally sized panes, and it's difficult to use and view in a single pane.

The problem has been even more economically solved by cancelling the shuttle
