On September 21, 2026, construction contractors working on a rail project between New Brunswick and North Brunswick, New Jersey, accidentally cut a Verizon fiber-optic cable. This severed a backup fiber line crucial for air traffic control communications, disrupting operations at the Terminal Radar Approach Control (TRACON) facility in Philadelphia. The incident caused the cancellation of more than 600 flights and delays to nearly 100 others at Newark Liberty International Airport alone by 6 p.m. that day. Philadelphia International Airport experienced over 200 cancellations and 400 delays, while New York City’s LaGuardia and John F. Kennedy International Airports faced FAA-imposed halts
and residual delays lasting into the afternoon.
Cause and Immediate Response
The fiber cut occurred approximately 10 feet from pre-existing utility markings, with NJ Transit identifying that its construction crew accidentally severed the cable while working in the area. Verizon stated its main facilities remained fully operational until the backup fiber was cut, denying responsibility and indicating technicians were deployed promptly to repair the damage. FAA Administrator Bryan Bedford explained, “when it went to flip into the backup, we discovered the backup fiber had a break.” Repairs began quickly, and flight activity had started to resume by that evening.
Newark’s United Airlines Hub and Flight Diversions
Newark Liberty International Airport, a
major hub for United Airlines, bore the brunt of the disruption. Over 600 flights out of Newark were canceled by 6 p.m., representing more than half the day’s schedule, with almost 100 more delayed. Nearly 100 flights originally destined for Newark were rerouted to alternative airports such as Detroit Metropolitan Wayne County Airport and Washington Dulles International Airport. Among the diversions were international flights from Berlin redirected to Detroit and a Stockholm service diverted to Washington Dulles.
FAA, NJ Transit, and Verizon Statements
FAA Administrator Bryan Bedford confirmed that operational difficulties arose once controllers attempted to switch to the backup fiber line due to a break.
NJ Transit publicly acknowledged its involvement, stating its crew “accidentally severed a fiber-optic cable while working at the site.” Verizon responded with a statement saying, “Construction contractors working in the area dug up and cut our cable. Verizon’s facilities were fully functional up to that point. Verizon bears no responsibility for this incident.” U.S. Transportation Secretary Sean Duffy commented on the impact, reinforcing the urgency to modernize the aging air traffic control infrastructure to prevent future system failures.
Traveler Impacts and Airline Responses
The fiber cut caused extensive travel disruptions for passengers, with hundreds of flights canceled or delayed across Newark, Philadelphia, LaGuardia, JFK, and
Teterboro airports. United Airlines waived all flight change fees and offered additional pay to employees who volunteered to pick up trips at Newark, easing operational strain. Similarly, American Airlines allowed affected travelers to change flights without fees and fly out of alternate airports to minimize passenger inconvenience. Flight operations began recovering later in the day as repairs progressed.
Context on Air Traffic Control Infrastructure
The outage exposed vulnerabilities in the current air traffic control technology, which officials have long noted as outdated. A multibillion-dollar modernization plan for U.S. air traffic control was announced by the Trump administration the year prior, aiming to upgrade equipment and reduce
incidents like the one caused by the severed cable. The disruption also coincided with the upcoming United Nations General Assembly in New York, a major international event amplifying the stakes of the incident in the Northeast U.S. airspace.
