Radar Outage at Newark Highlights Cracks in U.S. Air Traffic Control System

People wait in line for a delayed flight at Newark International Airport on May 5, 2025 in Newark, New Jersey. Air traffic controllers lost contact with aircraft heading to and from Newark Liberty International Airport last week, their union said, detailing an equipment failure that led to massive flight delays and raised more concerns about aging U.S. aviation infrastructure and staffing shortages.

The Incident and Its Aftermath

The controllers who guide flights in and out of the New Jersey airport on April 28 “temporarily lost radar and communications with the aircraft under their control, unable to see, hear, or talk to them,” the National Air Traffic Controllers Association, their union, said in a statement. Staffing shortages followed the incident, which was so severe that some of the controllers involved “have taken time off to recover from the stress of multiple recent outages,” the Federal Aviation Administration said on Monday.

Delays and Disruptions

There were more than 1,500 delays in the New Jersey airport last week, according to flight-tracker site FlightAware, as disruptions piled up because of shortages of air traffic controllers. “Our antiquated air traffic control system is affecting our workforce,” the FAA said. “We are working to ensure the current telecommunications equipment is more reliable in the New York area by establishing a more resilient and redundant configuration with the local exchange carriers.”

Response from Airlines

United Airlines said Friday that it will cut 35 flights a day from its New York City area hub at Newark because of the delays, in hopes of putting more slack into the system and ease disruptions. In a note to customers, CEO Scott Kirby said Friday that last week’s “technology issues were compounded as over 20% of the FAA controllers for EWR walked off the job.” However, the union denied that the controllers walked off the job and explained that workers took time off under the Federal Employees Compensation Act, which “covers all federal employees that are physically injured or experience a traumatic event on the job.”

Underlying Issues

The U.S. has faced a shortage of air traffic controllers for years. The Trump administration recently rolled out new incentives to hire and retain controllers, who are required to retire at age 56. The FAA last year moved controllers who are responsible for aircraft arriving and departing from Newark from a facility on Long Island in New York to a different facility in Philadelphia, in hopes of reducing overloaded controllers who were also handling traffic for New York City’s major airports.

Calls for Improvement

The Port Authority of New York and New Jersey, which oversees the major airports in the New York City area, said in a statement Monday, “The Port Authority has invested billions to modernize Newark Liberty, but those improvements depend on a fully staffed and modern federal air traffic system.” U.S. Transportation Secretary Sean Duffy last week visited the Philadelphia facility and said he will unveil plans for an “brand new air traffic control system” this week. New Jersey Gov. Phil Murphy on Monday urged Duffy to address the staffing shortfalls in the Philadelphia facility that oversees Newark as well as the New York facility that controls traffic in and out of LaGuardia Airport and John F. Kennedy International Airport, both in Queens.

Conclusion

The recent incident at Newark Liberty International Airport highlights the pressing issues of aging infrastructure and staffing shortages in the U.S. air traffic control system. The need for modernization and increased staffing is critical to prevent such disruptions in the future, especially with the anticipation of increased air travel demand.
