(1/11/23) The Federal Aviation Administration (FAA) grounded thousands of flights early today after a software failure. The problem involved the organization's Notice to Air Missions (NOTAM) system, which provides information for pilots about their routes and potential hazards.
The failure caused delays and cancellations of over 8,200 flights and over 1,200 cancellations before it was fixed. U.S. Transportation Secretary Pete Buttigieg said that an issue with NOTAM safety messages sent to pilots prompted the outage and called the ground stop the "right call" to make sure messages were moving correctly.
-"I once got a weather report (METAR) for Gallup, NM that simply said 'ROSNOT.' When I asked the briefer what that meant, he said he had no idea. So he called the observer (I’m dating myself here, phone calls amongst humans) and asked him what it meant. He said it meant 'Rattlesnake On Step. No Observation Taken.'”
