All flights in the United States are grounded until further notice “due to extraordinary circumstances and for reasons of safety,” the Federal Aviation Administration said in a statement.

The FAA issued the ground stop “following a communication issue impacting all Air Route Traffic Control Centers,” Secretary of Transportation Sean Duffy said in a social media post. “FAA technicians are investigating the issue.”

Air Route Traffic Control Centers are regional facilities that handle flights going across the country.

“Traffic should remain ground stopped until further notice,” the FAA said in an advisory. “International flights will be managed on a case by case basis.”

    Hey Claude, is runway 5 free?

    I wanted to make a joke like "no but runway 185 is" since the number of a runway is its degrees from magnetic north and each runway gets two numbers, 180 degrees apart, depending on the direction you're landing from. But the numbers are rounded to 10 meaning runway 5 isnt a real runway number so the joke doesnt really work (it would be runways 01 and 19 for 10 degrees and 190 degrees)

    There's a lot that goes into getting this joke, and even though you explained it. I still don't get it.

    I feel like half the joke is that Claude would infact consider runways this way and it's highly likely not understanding this or accidentally miscommunicating with it would induce the exact sort of fuck up he's describing.

    Also gcp grey has a video that explains this topic really well.

    September and claims it has already rerouted 180 flights for average savings of 10 minutes and 80 gallons of fuel, Ars wrote (that’s just shy of $345 per flight, at jet fuel rates of $4.31/gallon as of Thursday).

    A tool that cost a little under a BILLION dollars…so far…saved $62,000? That’s the stupidest waste of taxpayer money in the last 5 minutes with this administration. And of course it saved airlines the money, while taxpayers got stuck with the $800 million dollar bill for the WalMart brand airplane route planner.

    It's not going to save anyone any money on flights because companies just pocket the difference, but does anyone know how the jet gas/ diesel/ consumer auto gas markets are connected? Is there a chance the reduced jet fuel demand reduces prices at the pump? That's probably the bigger picture goal here even if it doesn't actually work that way, because our government is run by dumbasses who wouldn't even think to ask if they're connected.

    This looks like one of those large upfront costs things that saves money over the long run because new critical infrastructure systems always cost a lot upfront and need a slow rollout to prevent things like, say, grounding every single flight in the country, but long term pay for themselves. On paper I'm usually in favor of short term spend for long term savings but unfortunately this is a kleptocracy and this is an indirect handout to the airlines.

    The petroleum market is very complex and I don’t have the brains to dig into it. Suffice to say that thanks to all the bombs and missiles flying around and hitting oil infrastructure right now the markets have become unhinged as far as what oil costs and what refined products cost and the reltaionships between those and market/future prices. IOW per bbl cost can be down and gas prices up, or vice versa. For now though just know that it’s going to be years before proces could start coming back down thanks to the destroyed refining and shipping capabilities.

    But anyway, you already answered your question…they pocket the difference. And odds are that even if refining capability catches back up, consumers won’t see a commensurate drop in price. “Record profits”, y’know.

    FAA denies it's related to the new system. they say it's a communication equipment outage.

    ... From the CNN article linked in this thread:

    Homeland Security Secretary Markwayne Mullin pointed to FAA updates to the air traffic control system as the reason behind today’s nationwide ground stop. He said the FAA added new technology to the old system, causing the massive breakdown.

    yeah but it wasn't the ai system

    an update to the private communications network that connects America's air traffic control system caused the system to reboot, leading to a crash and a communications outage

    They were all nearing retirement age at the same time because Ronald Regan fired all their predecessors when they went on strike back in the 80’s. Having a critical highly trained workforce with hard retirement limits (they’re not allowed to work till they’re 85 like Senators) all on the career cadence has been a ticking time bomb.

    In addition to his other duties, Flavor Flav is also official timekeeper for the FAA. He keeps all the clocks synced in the nation's air traffic control towers. He just had a sick day today.

    What else do you think the clock was for?

    He saw the FAA announce the rollout of a new system to replace the old reliable one that was created by people who knew wtf they were doing.

    They just upgraded from floppy drives. My money is on them letting a virus into the system, or that the new system had major security problems.

    https://www.techspot.com/news/114471-almost-2027-faa-finally-replacing-floppy-disks-used.html

    "The FAA wants E-IDS installed at 435 facilities by the end of 2028. Five sites have already replaced their floppy disk-based systems: Atlantic City International Airport, Nashville International Airport, Greater Rochester International Airport, and data processing hubs in Atlanta and Salt Lake City"

    Edit: it looks like they also just started expanding and AI traffic management system nationwide.
