A nationwide flight outage exposed the deteriorating state of US aviation infrastructure, with thousands of flights canceled or delayed on November 13.
US Transportation Secretary Sean Duffy blamed decades-old air traffic control equipment, admitting: "We're using small copper lines from the 1980s. It's an old system that has gone down and down everywhere. It was too busy."
■ Despite the flights resuming after more than four hours, Duffy warned: "But you will have more of these," and admitted that there could be further disruptions nationwide.
■ Calling the situation an "emergency," Duffy demanded $50 billion from Congress to overhaul the nation's aging air traffic control system.
