This piece hit hard. It’s strange how something so invisible to most of us is simultaneously one of the most complex, tightly-coupled systems running in the background of daily life.

Kind of curious how air traffic control evolved in other countries, and how the international flight system works with handoffs between countries, particularly in Europe and the Caribbean where national borders tend to be relatively small.

This was indeed normalized very early on in post WWII european construction:
My grandfather flew Typhoons, and they operated 'cab rank' as part of the 2nd Tactical Air Force. The Army would radio in coordinates of German tanks or fortified positions, and the Typhoons would come in with their rockets / bombs / cannons. I wish he was still around so I could ask him how that was done. A central dispatcher? Or did they talk to the Army directly? Not sure.
And before GPS they'd reckon their position off of landmarks and terrain?

There were a great number of inventive aerial navigation systems that predate GPS by many decades. One of my favourite books is Most Secret War[0], a biography by R.V. Jones that details much of the cat and mouse that went into detecting and countering the various systems used by the Axis and the Allies to bomb each other.
There was a lot of development around radio navigation aids in the interwar period. I believe it was even possible to navigate using commercial AM radio broadcasts, as long as the location of the broadcasting station was known. So while the basic method was computing location based on speed and compass bearing from a landmark (possibly accounting for wind drift), I believe a certain level of radio navigation was still going on in cases of adverse weather.
Longer-range bomber flights also did it the same way ocean-faring ships have done in the past few hundred years: they had a roof window for taking celestial fixes with a sextant. Come to think of it, that's how the Apollo capsule also confirmed its location.

Isn't that still how it's done? - When leaving earth orbit there isn't GPS or such, the guidance to the moon or further still uses star trackers.

The Voyager space probes for sure use visual fixes on guide stars, such as Alpha Centauri (and our own Sun?) to ensure correct orientation. Of course, they don't need to navigate much, since given the relative velocities, their thrusters wouldn't make much difference.
And there is a quite-famous scene in Apollo 13 where they literally line-up the Moon itself in the reticule so that their engine burn puts them on exactly the correct trajectory.
I believe several of these were also used by civilian aviation before and after the war
TL;DR: both sides used systems with multiple ground antennas that allowed pilots to essentially triangulate their position or at least know they're in a given lane.

As an aside, wasn't there some HN post a few months back about how carrier warfare in the Pacific led to more and more complex schemes of ATC, aka "Fighter Directors", including early Naval computers devoted to figuring out where to put airplanes in the right place at the right time right time?

I read in A Bridge Too Far, the Hawker Typhoons that attacked German positions at the start of the Operation (called in by the Forward Air Comtroller), flew under the opening barrage and one Typhoon disintegrated as it was hit by a shell. I've often wondered if there was any system in place to prevent that sort of thing.

I don't think there's any debate that ATC staffing is a major issue right now, and the FAA really did blow up its hiring pipeline to further DEI goals
This involved a completely nonsensical and arbitrary biographical screening test, which:
1. was designed to statistically select for members of favored identity groups and against members of disfavored identity groups, and not in any way to measure ATC job aptitude, resulting in highly-scored questions like "The high school subject in which I received my lowest grades was" where the only correct answer was "Science", and failing the test disqualified you permanently
2. then-current FAA employees distributed the exact answer key to outside racial identity organizations to give to their members
15. The high school subject in which I received my lowest grades was:
A. SCIENCE (+15)
B. MATH (0)
C. ENGLISH (0)
D. HISTORY/SOCIAL SCIENCES (0)

The first link describes it as one half of a two-step screen where there are known biases in the second step, and there are far more applicants than positions. So the entire point of this quiz is for it to have a deliberate designed complementary bias, so that the outcome of the two tests combined gave a score that was statistically correlated with the desired results and NOT statistically correlated with characteristics they did not find useful.
Is your argument that this is a bad goal to have, or a bad method of approach, or that the quiz created cannot possibly achieve this goal?

This story has really annoying results, because while there were dumb decisions made about the hiring process, people are also blowing some things out of proportion.
There's lots of terrible personality tests in recruitment and they're sometimes abused for various purposes. This one is just mildly bad compared to for example corpos hiring people to analyse the signature/writing style of the candidate. But handing out the key to that test was just terrible.
Then there's another one where people reacted strongly to someone handing out highly scoring words for the resume... where the words would be included in any basic coaching like "leader", "ownership", "delivered", etc.
It's hard to even talk about this when people have kneejerk response to a few key phrases here.

I think you're missing the context of the article the grandparent was quoting. The article begins:
> Air traffic control has been in the news lately, on account of my country's declining ability to do it. Well, that's a long-term trend, resulting from decades of under-investment, severe capture by our increasingly incompetent defense-industrial complex, no small degree of management incompetence in the FAA, and long-lasting effects of Reagan crushing the PATCO strike. But that's just my opinion, you know, maybe airplanes got too woke.
So when the grandparent quoted
> maybe airplanes got too woke
and THEN says "I don't think there's any debate that ATC staffing is a major issue right now, and the FAA really did blow up its hiring pipeline to further DEI goals", what does that quote add?
I read an implicit statement that the commenter is siding with this as the cause of the industry problems: "I don't think there's any debate that" [it is, in fact, wokeness that has caused the industry problems]. And I don't think their linked article does make an airtight argument for this.
Perhaps you think the steelman version of the comment simply treats the quoted fragment as an accident, or irrelevant to the rest of it, but I disagree.
This seems like it was pretty bad, but I worry we may be doing the same thing to every federal agency now.

If you look at how they're scored, it's worse than Meyers-Briggs. Wanting a specific personality type for the job makes a lot more sense than many of these.

Have a lot of points!). Even ignoring the rest of the story, it's a very flawed test.

This is often said, but misses entirely the forest for the trees.
The ATC shortage is not in the pipeline of candidates, so this is irrelevant - in fact there's a backlog of people who have been accepted. It's in the training of those candidates - because it's an intensive training there isn't enough staff to increase the amount of people being trained at the same time, which is very insufficient. Furthermore, after finishing their training, folks are posted randomly and some refuse (and thus leave the ATC job) because they don't want to move them and any potential family to the middle of nowhere.
When your hiring pipeline is so obliterated that you decide to fire about 400 of your employees. Makes sense.
jillesvangurp 2 hours ago [-]
The historical perspective is kind of interesting. What interests me more is how this stuff can be modernized. Because the current byzantine system of task saturating people by making them yell numbers and letters at each other over state of the art 1950s technology for doing so is hardly efficient, scalable, or ultimately secure when it inevitably breaks down under the stresses it induces on pilots and staff involved.
Communication failures and pilot errors are usually major contributing factors to accidents. Pilot errors become more likely when individuals are preoccupied with processing vast amounts of information and demands thrown at them via radio in critical parts of flight (e.g. when finding their way to a runway).
Most of the radio calls today (>95%) are bog standard verbal exchanges about things that should not require any humans in the loop. Anything to with weather is just numbers that can and should be be exchanged digitally. Much faster, less room for error. There should be zero confusion about what the altimeter settings are at a particular airport, what the active runway is, where the wind is coming from, etc.
Anything to do with "who are you and why are you here", which is a disturbingly large proportion of verbal exchanges, sounds like it could be established both more securely, robustly, and efficiently. We have computers now with things like secure hashes, uuids, certificates, etc. Any time you have enough bandwidth to talk to somebody you definitely have enough bandwidth to throw quite a bit of data around securely and reliably.
If you call your granny via whatsapp, facetime, or whatever, there's no need to tell her who you are. Because the app tells her before she even answers. It's completely redundant information. She already knows. There's no valid technical reason why ATC cannot have the same comfort of knowing who they are talking to and what they are flying. It's 2025! Not 1965. ATC should have full context when they talk to people. They shouldn't have to ask for that context verbally. Routine course changes, altitude changes, etc. could be communicated and confirmed via computers. Voice channels should be used for emergencies and non standard situations only.
There are a few things happening in aviation that are making this more urgent after many decades of stagnation in technological changes. Battery electric is going to make flying vastly cheaper and safer than it is today. That's going to increase the amount of relatively inexperienced pilots and plane movements. And secondly, there are an increasing amount of autonomously flying planes, drones, etc. Those are actually going to dominate traffic in the years ahead. Pilots are expensive and are becoming kind of redundant. The amount of flights that ATC needs to juggle is going to increase by at lease one or two orders of magnitude.
The current system won't scale with that, it will have to change. Now would be a good time to start figuring that out.
wezdog1 2 hours ago [-]
I take your point but simply throwing silicone at the problem doesn't make things all of a sudden better. Wind data can already be uplinked to aircraft through ACARS anyway. The problem is aviation is very dynamic. You can't fly the plane and get a bing bong message cleared to land and not be distracted by it. Voice comms are flawed but one of the benefits is you can hear them and monitor the aircraft state. ATC have systems which add another layer of protection for a misidentified runway for example.

The problem is, for that to work, you'd need to push a worldwide coordinated effort to upgrade everyone. Hundreds of thousands of GA aircraft, historical aircraft, about 30k commercial aircraft and most likely hundreds if not thousands of different models. For each of these you'd need to develop and most importantly certify a digital avionics package. And you'd need to train about half a million pilots for commercial flight, on top of that all the GA pilots.
And no, "give pilots an iPad" doesn't count. That's what many airlines are already doing so pilots have an alternative to paper charts of approaches or on-ground navigation... but the old paper and radio? That all still has gotta be present because that stuff is actually certified to be redundant and (largely) fail-proof.
There's a reason innovation speed is very slow in aviation: it took decades worth of work and many thousands of deaths to get aviation to be what it is: the most safe way of transportation by far. You probably have a higher chance of getting hit by a drunk driver than to even get a small injury on a commercial airplane, because all the failure modes of airplanes and individual parts have been worked out. Every kind of new part, new systems and new material introduces new failure modes that have to be discovered, mitigated and the mitigation be distributed around the world.
