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.

They're using OurAirports data, filtered to exclude all but "large" and "medium" airports. Anything smaller than that includes all sorts of cruft like African bush landing strips, heliports, etc.

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

It's not smooth, but totally usable on my i7-3770K workstation.

For what it's worth, it's also fun that key elements of the text are dynamic. When I first landed on the page with noscript suppressing any script, I saw:

> Most Remote Airport

> … at … is the most remote; from the nearest airport, .

Usually if I see any text, I don't bother enabling script, so this confused me. Luckily I did enable the script and then saw the principle UI element on the page. :)

Hmmm, which one is the result of a team of experts competing with other major corporate entities, getting paid to optimize a set of well-known algorithms for months prior to delivery to an audience of millions who will spend thousands of hours with it and which one is a one-off hack meant to demo the first iteration of some new code for the first time on its new platform?

Pretty soon there's going to be a nice big new polygon added in the middle of the South Atlantic: https://en.wikipedia.org/wiki/Saint_Helena_Airport

Looking at the map, I am liking some of the place names on St. Helena; "The Gates of Chaos" is a particular favourite.

What a cool project! This is very fun to play with in conjunction with the ETOPS (extended twin-engine operations) settings on the Great Circle Mapper. http://www.gcmap.com Among other things it drives home how remote the waters MH370 disappeared in are.

I recently did ORD-HKG and spent quite a lot of time thinking about ETOPS diversion airports over Siberia (because honestly what else are you gonna do). Now I'm wondering if you can even land a fully laden 777 at any of them. Most of them don't even seem to have wikipedia pages.

I know right?? It's mind-blowing! My PC can push millions (is that the order of magnitude?) of polygons per second. But it locks up an entire core to render a couple hundred polygons (plus the layers of cruft), and can't do it at more than ~10Hz.

Adding an airport will SHRINK a polygon. A bigger polygon means a greater distance to the nearest airport. Edit: Never mind, on thinking about your comment some more, you probably know that.

Where you will see larger polygons is across the United States, as corrupt local governments get paid by land developers to close airports and sell off the land. Often these kangaroo councils operate under the guise of pandering to local residents, who moved next door to an airport and then started bitching about it in hopes of having it closed and boosting their property values once.

Make no mistake: These people are stealing from all of us. Once an airport is closed, we'll never get it back, and part of our national transportation infrastructure is destroyed. Not to mention the damage to the future of aviation, which can't fund innovation and invention if there's no place to land. See the current scam that's threatening the Santa Monica airport for an example.

This is what happens when clowns and criminals run a city government: We can laugh at them, but they cause real and permanent damage.

Not addressed to you, rather to a sibling commenter. Hellbanned users cannot be directly replied to. ngoldbaum, you should check a user's comment history before alerting them to the fact that they're hellbanned. If there's a clear reason then don't. In this case, he was hellbanned because he called someone an idiot on his very first post.

Really? Even if they continue to comment productively afterwards?

I think it's sad to see a hellbanned person contribute productively, since obviously they have no idea they've been banned.

Well, check for sure but it comes down to opinion at that point. Hellbanning is a pretty extreme choice for someone who made a fairly small mistake like that.

"In addition, astronauts now carry passports and other documents, including traveller's cheques, in case of emergency landings."

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.

Space shuttle cargo was something like $20,000/pound. If each astronaut needs a pound of paperwork for contingencies (which seems like a vast overestimate) then that's $20,000 each, which is tiny. And the marginal cost per pound was small. Given that you're doing a launch anyway, you're probably not exactly at the mass limit, so a few extra pounds of paperwork costs almost nothing.
