6,000 flights canceled in U.S. air chaos

More than 6,000 flights were canceled across the United States on Saturday, according to flight tracker FlightAware. The massive disruption followed a nationwide ground stop that grounded aircraft for over four hours on Friday. Federal Aviation Administration Administrator Bryan Bedford said the system should be back to normal by the end of Sunday. He described the situation as the worst being behind us. This event marks the longest ground stop in the country in 25 years.

Transportation Secretary Sean Duffy identified the source of the problem as a contractor's work on the air traffic control system. L3Harris Technologies Inc. was replacing old copper wire with new fiber wire. Duffy stated that this work caused the system to overload. The error led to intermittent communications and gaps in radar data. Officials are investigating whether the issue stemmed from contractor incompetence or a faulty router. Duffy noted that either the contractor or the equipment failed to meet the moment.

The FAA usually consults its own technicians to assess risks before performing upgrades, but that step did not occur in this case, according to the Professional Aviation Safety Specialists union. The union represents the agency's technicians. This incident is the first nationwide stop since January 2023 and the second since the September 11, 2001 attacks. Aviation consultant Andrew Charlton estimated that Friday's stoppage affected about a quarter of the 45,000 flights that typically operate in the U.S. each day.

Charlton explained that the knock-on effect of such a disruption is incredible because aircraft do not simply fly from point A to B and stop. They continue to other destinations, creating a chain reaction. He noted that the chaos is exacerbated by long-haul international flights. At airports across the country, passengers scrambled to find new ways to reach their destinations. Some stayed in hotels, while others sought rental cars or train tickets. Many waited in terminals, and some engaged in activities to pass the time.

In Seattle, a passenger played classical music for stressed travelers. In Lexington, Kentucky, stranded strangers played a cornhole tournament. On commercial airplanes, singer T-Pain and the band Hoobastank were recorded singing to waiting passengers. Dan Russell, 66, learned his connecting flight from Hawaii to California was canceled a half-hour before boarding in San Diego. His wife and he waited at the airport because hotels were full. Russell said there was nothing they could do.

At Newark Airport in New Jersey, Umi Egchi tried to determine when he could return to Japan. He wore a sleep mask on his head and said he just wanted to go home. Sports teams also felt the impact. The No. 19 Mississippi football team had to delay its game at Oklahoma until Sunday. Duffy stated that no one was in danger during the ground stop. More than 3,000 flights in the air at the time landed safely.

Officials in the Trump administration blamed Congress for not approving enough funding to replace decades-old technology. Duffy said 70% of the system has been replaced, but the agency needs new towers and runways. The FAA has spent $12.5 billion on upgrades since last year, replacing thousands of copper wires with fiber optic lines. The administration wants an additional $30 billion to complete the work. Duffy emphasized that flying remains safe despite the aging infrastructure.

Aviation safety expert Steve Arroyo, a former United Airlines pilot, said the difference in this disruption was its scale. Controllers were unable to reliably talk to pilots. Arroyo explained that if controllers cannot communicate, they must stop planes on the ground. He noted that old wires can run down, necessitating a halt to operations. President Donald Trump has not spoken publicly about the issue but spoke on the phone with a Fox News reporter.
