SocietyUS nationwide flight halt: ‘Our routers got overloaded with data’

The Federal Aviation Administration issued a rare nationwide ground stop on Friday, leading to more than 8,200 cancellations—over 31% of scheduled US flights. It lasted nearly five hours, the longest in the country since September 11, 2001. Officials blamed outdated air traffic communications equipment and said there was no evidence of a cyberattack. Airspace has reopened and flights have resumed.
