If true and this ends up lasting an hour or more, that's going to be undeniably, objectively hilarious. At least they used to keep the planes running on time!

--- EDIT:

This could just be the first issue that's arisen -- the FAA announced it "is expanding across the nation" on Tuesday. Which could really mean anything.

The Ars Technica article behind the Gizmodo one sadly doesn't have more info, either.

It'd be kind of absurd if a read-only integration took down nationwide infrastructure, but A) we've all been there... and B) the gizmodo article does mention they're also trying to phase out floppy disks for some jobs still, which tells me their CI/CD and rollback hygiene might not be top-notch. Hopefully the Real World contestant in charge of our transportation network is on site with a ClaudeCode terminal as we speak!

It does sound pretty deeply integrated, I will say:

  SMART is a cloud-based system that centralizes 200 data streams – including weather patterns, flight paths, traffic flow, and controller staffing metrics – into one platform.

The fact sheet has two more vaguely worrying bullet points -- I would say such wild speculation is unwarranted, but I struggle to think what else could cause all the radios in the nation to go down at once... Emphasis mine:

  Creates **a single shared real-time picture** of schedules, weather, airport capacity, and airspace conditions.
  ...
  Enhances the effectiveness of **existing** FAA air traffic management systems.
