A major air traffic control outage has disrupted flights across the American Midwest. The failure occurred at a facility in Minnesota. Radar and radio systems went down. The FAA grounded flights across nine states covering 330,000 square miles.
The outage struck the Minneapolis Air Route Traffic Control Center. It is one of the busiest facilities in the national airspace system. The failure affected flights across Minnesota, Wisconsin, Iowa, and surrounding states. Minneapolis-St. Paul International Airport imposed a ground stop. Airlines including Delta, United, and American reported delays. The FAA said the issue was a temporary equipment failure. It did not cite a cyberattack. US aviation infrastructure has faced scrutiny after recent near-miss incidents. Aging systems and staffing shortages have strained controllers.
The FAA restored normal operations after several hours. Airlines are working to clear backlogs. Passengers faced cascading delays into Friday. The incident reignited debate over US aviation infrastructure investment. Lawmakers have called for hearings. The Biden administration has pushed for modernization funding. Republicans have blamed administrative failures. The outage came as the US is already on edge over the Iran war and domestic security. Aviation experts say redundancy systems prevented a worse outcome. The full cause of the failure is under investigation.
