US air traffic control still runs on floppy disks, for now

On the day a nationwide ground stop halted US flights, a Reuters report resurfaced. It says the FAA plans to phase floppy disks out of air traffic control by 2028. The ground stop itself was reportedly blamed on a network update that crashed the FAA's telecom infrastructure, not on the disks. Still, the detail shows how old some of the machinery behind the world's busiest airspace is. Officials say the replacement is under way, and the target date is still two years off.
