My hot take:
We all know Trump has dementia.
So he just walked out in the evening and boarded a plane, not knowing where to. The others didn't see him leaving, so they didn't know either.
When he messaged to his folks that he is going to take off in a minute, they grounded everything immediately, just to be sure.
Then it took them only 4 hours because they are the world's smartest ones.
I just now read regional traffic control centers, which link all the others, got overloaded with data traffic because the FAA communication system is a patchwork mess - multiple generations of new tech integrated with old legacy systems and each other over a long span of time. That kind of setup can be nursed and prodded along for years by dedicated maintainers, but at some point the upside-down Slurpee cup that's been holding up one end of the shelf crumples and everything falls on the floor.
It was fine until these dumbfucks pushed AI without testing it. Who are you trying to glaze?
Olivia Rinaldi was claiming over on Twitter that the FAA did an update to their telecommunications equipment, which caused a reboot. However when the system rebooted it immediately crashed. So since their communications are borked they just grounded everything.
Is it true? No idea.
probablt intentional since duffy came out with demanding "50bn" so that it wouldnt happen again.
Informed speculation but I believe this is correct. Specifically new modern (maybe vibe coded) software that is probably really tough to integrate with the hodgepodge of ancient systems current propping up our control system.
There's no official word, but to add some context, the FAA deployed a new AI-powered computer system for air traffic control yesterday.
Again, no proof that that's what's going on. But it sure is interesting.
They've officially denied this as being related.
So it probably is.
I watched the press conference and they admitted that the AI (actually, it's called SI) systems overloaded the old routers so that's why we need $50B in emergency money from congress because Trump is a builder and he knows how to build and also previous administrations were also partly to blame
That's the summary if you haven't see the press conference
FFS
I'm tired of being right.
Edit: who's going to be the no-bid contract winner?
Honestly, with this administration, that's practically a confirmation that it is AI.
With this administration it could be literally any number of dumb fucking reasons.
As someone who's grounded, this was my theory as well. They're blaming old routers and software, but who wants to guess it couldn't keep up with the roll out?
An AI posted system... powered on Copilot?...
I CAN'T HELP but think it's low key another stunt to, yet again, drive up fuel and travel prices RIGHT before the holiday!
Think about it, all these people now need to rebook travel, creating demand for planes/seats/times, and as demands rises we KNOW ticket prices do too.
That's, IMHO, why there's no announcement as to why there are no flights right now.
Airlines have to rebook these people for free, but it will still push prices up because the demand is the same but the supply got crunched.
Yeah agreed, I didn't clarify very well!
Could be a false flag for an attack on Iran this weekend.
We never had these kinds of outages before they got rid of DEI.
Bring back the twinks!
IMO theyre keeping it under wraps for one of these reasons:
It's because they're using teams
As someone who is forced to use teams at work, if pilots used teams every single flight would crash, no exceptions.
Maybe the scariest possibility.
It could be something totally innocuous. Last time this happened it was because one engineer pushed an update that broke everything, iirc.
You mean the clownstrike?
Ha hahahhaha
Hahahhahahha
FAA ATC isn't using computers that can even run Crowdstrike, so they were safe from that.
I was on a flight when everything was grounded. I asked the pilot and he could neither confirm nor deny that it’s aliens.
My connecting flight was cancelled so I split a $600 Uber with four strangers
My brother is an ATC. He didn'y have any more info yet, but I'll update this comment when he knows more.
Edit: Just had dinner with him and he didn't have any official info. He did say that
He didn't buy the official story of there being a communication issue between airports. It just doesn't make sense based on how those communications networks function (sorry wish I had more detail here. he went into copper wire laid in the 1960s and how it's different than just the public Internet.) But they wouldn't ground crop dusters and planes flying VFR out of small airports if it were a communication issue.
The AI rollout that has been in the news also very likely has nothing to do with it. Absolutely NO controllers have been breifed on any new systems, so it's likely just something to grab a headline from the Trump administration.
It was his day off but his work called twice while we were at dinner trying to get him to come in.
probably to extort 50bn from congress, duffy is now asking if they want toa void another "grounding of the flights" just a few hours.
I patiently await the update
Just posted an edit. Sorry it's not much.
Trump heard ‘the copilot’ was down and thought ‘but how are they going to land the planneesss? And grounded the country
This is quite literally possible.
The actual advisory from the FAA is:
ATCSCC Advisory
ATCSCC 111 DCC 11/13/2026 NATIONAL GROUND STOP
MESSAGE:
EVENT TIME: 13/2053 - 14/0400
DUE TO EXTRAORDINARY CIRCUMSTANCES AND FOR REASONS OF SAFETY.
ATTENTION ALL AIRCRAFT OPERATORS, BY ORDER OF THE FEDERAL AVIATION
COMMAND CENTER ALL AIRPORTS ARE GROUND STOPPED. ALL DEPARTING
TRAFFIC SHOULD REMAIN GROUND STOPPED UNTIL FURTHER NOTICE. INBOUND
INTERNATIONAL FLIGHTS WILL BE MANAGED ON A CASE BY CASE BASIS.
EFFECTIVE TIME: 132054 - 140430

Beyond that, all I've seen so far is:
Markwayne Mullin, the secretary of homeland security, says Trump administration officials blamed a telecommunication outage but said they did not know its cause and that it would “take some time” to fix the issues grounding flights.
per NYT's reporting: https://www.nytimes.com/live/2026/11/13/us/ground-stop-nationwide-flights-faa/d2ae2ce1-ac6b-59ad-ad8d-daef4e181b34
Edit (longer quote further down from Mullin):
Markwayne Mullin, the secretary of homeland security, blamed the ground stop on a telecommunication outage but said Trump administration officials did not know the cause, adding that it would take an extended period of time to fix the issues. “This isn’t going to just be resolved and turned around within the hour,” he said. “This is going to take some time.”
The extraordinary circumstances, probably:
My theory: Trump Admin hired someone incompetent and they fucked up the comms. I mean that just the theme of trump admins basically
Outlook and Teams outage /s
Honestly wouldn't be surprised if air traffic control is run off of one massive excel document
A million different sheets all labelled "New Sheet 1" "New Sheet 1 (1)" and so on
That functions via a series of complex formulas and macros created by an ex-employee that no current employee understands.
It was a router issue that cascaded to the other locations.
