Obsolete technology blamed for chaotic ground”: The US suffered one of the largest aviation disruptions since 9/11.
"Flights have been restored in the US after a large-scale malfunction in the air traffic control system. The Federal Aviation Administration lifted a nationwide flight ban that paralyzed airports across the country for nearly four hours. By Friday evening, more than 8,000 flights in the US had been delayed and about 7,000 had been canceled. The reason for the collapse of the radar control and communication systems was a disruption of the air traffic and communication systems.
US Transportation Secretary Sean Duffy said the failure was due to outdated 1980s infrastructure that was overloaded. Authorities said there were no signs of a cyber attack but the investigation is ongoing. Even after flights resume, it will take time for airlines to return to normal schedules - some planes and crews arrived at the wrong airports where they were supposed to be. It was one of the biggest disruptions to the US aviation system since attacks of September 11, 2001. A similar shutdown occurred already in 2023 due to a failure in the NOTAM system.
