I expect that out of any random sample 500 million literate and mentally healthy English speakers, more than 450 million of them are totally unaccustomed to thinking about nautical miles ever. Even people in science, or even who might have dealt with nanometers in school do not typically think about nautical miles unless they are sailors or airplane pilots.
I've never had cause to see the abbreviated form of nautical miles, but I know nanometers. Also, given purely the title I could see it being some kind of data collision due to precision errors between to locations that should be the same airport but perhaps two different sensors.
Turns out 3600 NM = 6666 km
So, yes, people who have worked in a related field get it. Still annoying though.
The article title is talking about location data and computers, I've seen many people forget floating point precision when comparing and getting bit by tiny differences at the 10^-9 or smaller. That seems just as obvious on the outset as non-unique location designations in what the average person would assume to be a dataset that's intentionally unique and unambiguous.
But this is Hacker News, not Aviation News, and there are plenty of people, like me, who might find this interesting but aren't in aviation. I also thought it meant nanometers.
Exactly, which makes the headline particularly intriguing—how could a 3600 nanometer difference matter? The standard resolution, which I pursued, is to read the article to find out, but it doesn't mention the distance at all.
