If you're ever on an airplane, go to the map feature in your in-flight entertainment, and look up the town of Nadi, in Fiji.
Because its airport code is NAN, and because everyone in my profession is somehow really bad at their jobs, the map might think the airport is "Not A Number", at which point you can expose all sorts of fun bugs.
In my case, whatever city you had looked up previously would be shown, but still labelled "Nadi".
@pjf this is amazing. Airport codes are confusing but maybe don’t interpret them as anything but an opaque string
@pjf Paging @badedgecases, if they’ve made it here yet…
@pjf Apparently Google Maps had to add a filter to auto reject landmark submissions located in the ocean south of Ghana
@pjf And here I thought our work flight booking system was bad because searching for Stockholm defaults to Stockholm, Papua New Guinea (which is apparently a plantation with a crop dusting strip)
@pjf Now I want someone to look up either In Guezzam airport in Algeria, or Inverness in Florida, both of which have codes INF (though in different systems).
@pjf we also found if you hadn't looked at a previous city all the values would be missing.
@pjf That... just... I mean, why would...
@pjf OK, after spending more effort thinking about it, I can see a scenario that caused that behavior, and it makes me sad. But also zero surprise, because data protocols are hard. Apparently.
