As of thirty-ish minutes ago ALL commercial air traffic in the US is grounded until further notice.

Anyone got any idea what’s going on? There are very free details about the situation I can find online right now.

    Because it’s a nation of incompetents, ruled by incompetents, who are now trying to force incompetent ai into positions demanding competence.

    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.

        Part of the problem is that the flight control system is fully owned and operated by the FAA and the agency has issues implementing a multi-year modernization program. It would likely work a lot better if the modernization program was run through the municipal airports.

        No, hodgepodges of old, difficult to maintain systems are not fine.

        Don’t conflate the saying “if it ain’t broke, don’t fix it” to be the same as “if it works, don’t fix it”. Plenty of things can continue working when broken. That doesn’t mean you shouldn’t fix them. You shouldn’t fix them with LLM slop, but that’s a different issue

    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.

    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.

      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.

      I would expect there to be primary and backup services of communication. Such a massive/critical update would most likely be tested on a smaller region with the capability to fall back to the backup servers.

      But also hearing how outdated and antiquated a lot of the facilities are (I know they’re rushing to upgrade everything from floppy disks), I could bet that the backup transmission services might not even be operational for some facilities.

    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.

        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

        Honestly, with this administration, that’s practically a confirmation that it is AI.

      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?

      They didn’t deploy it yesterday. They expanded it yesterday. It has been in use for a couple months so far.

        Well, they expanded it from a single test installation to nationwide on the 12th. Which meets my personal criteria for “deployment”.

      The current SMART roll out should have been nothing but route optimization, if human controllers agreed. OTOH, that’s one hell of a coincidence if that was related.

        It’s the SMART rollout for sure. The failure point was old analog hardware that couldn’t keep up with the sheer pummeling the AI algorithm was dishing out to accomplish effectively nothing the controllers couldn’t do before.

      I bet it thought it was directing real air traffic but in reality it was traffic from Microsoft Flight Simulator.

    IMO theyre keeping it under wraps for one of these reasons:

    • it was an attack and they dont want panic
    • it was yet another huge failure of “ai” bullshit and they can’t upset shareholders any longer so need to keep secret
    • it was floppies

    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

    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.”

    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

    1. 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.

    2. 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.
