A Verizon fiber optic cable was accidentally cut on September 21, 2026, near New Brunswick, New Jersey, causing radar and radio communication failures at the Federal Aviation Administration’s Philadelphia Terminal Radar Approach Control facility. This outage disrupted air traffic control for Newark Liberty International, John F. Kennedy International, LaGuardia, Philadelphia International airports, and smaller regional airports in New Jersey and Pennsylvania, triggering widespread flight delays and cancellations across the region.
Newark and JFK Account for Most Cancellations
Newark Liberty International Airport experienced no commercial flight landings for about eight hours, with over 600 flights delayed or canceled. Philadelphia International Airport reported approximately 400 delayed and 200 canceled
flights on the same day. Ground stops extended to all New York City–area airports, severely limiting arrivals as FAA controllers reverted to backup procedures. International flights were diverted to secondary airports, including a United Airlines flight from Berlin redirected to Detroit Metropolitan Wayne County Airport and a Scandinavian Airlines flight from Stockholm diverted to Washington Dulles International Airport. The disruption cascaded nationwide, causing nearly 4,000 flights to be delayed and close to 500 canceled across the United States. On the West Coast, San Francisco International Airport recorded over 400 delayed flights as aircraft inbound to the affected northeast region were
held or delayed.
Cause and Response to the Fiber Optic Line Cut
The outage resulted from a construction crew working on a rail project between New Brunswick and North Brunswick, New Jersey, accidentally severing a Verizon fiber optic cable approximately 10 feet from marked utility lines. Verizon stated that its construction contractors had “dug up and cut our cable” but emphasized that their facilities were fully operational before the incident and that Verizon bore no responsibility for the event. FAA technicians discovered that both the primary fiber optic circuit and the backup fiber line were cut, causing complete loss of radar displays and radio connectivity critical for the Philadelphia
TRACON facility. FAA Administrator Bryan Bedford reported, “when it went to flip into the backup, we discovered the backup fiber had a break.” Repairs to the damaged telecommunications lines were completed by Monday evening, allowing restoration of normal radar and communications services.
Passenger Disruptions and Airline Responses
The fiber cut forced travelers into hours-long delays, missed connections, and uncertain travel plans at several major airports including Newark, JFK, Philadelphia, and LaGuardia. Crowded terminals and long lines for rebooking were reported, with some passengers facing overnight stays away from their original destinations due to flight cancellations and diversions. United Airlines, operating a major hub at Newark,
described the situation as a technology failure affecting all Northeast airlines, with flights either held at origin airports or diverted to others. American Airlines waived change fees and allowed affected passengers to use alternate airports for departures. NJ Transit confirmed its crews were investigating the utility marking responsibilities and repair status at the incident site.
Official Statements on Incident and Recovery
Transportation Secretary Sean Duffy characterized the outage as stemming from an initial circuit failure compounded by damage to backup fiber optics, emphasizing the need to modernize aging infrastructure. FAA Administrator Bryan Bedford acknowledged that switching to backup fiber revealed additional line damage, complicating recovery. Verizon
confirmed that construction contractors cut the fiber cable but denied responsibility, stating their facilities were fully functional until the incident. NJ Transit reported its crews were actively working at the site to assess repairs and investigate the utility marking responsibilities. United Airlines highlighted the broad impact on Northeast airlines and noted ongoing operational adjustments including flight holds and diversions.
Infrastructure Concerns and Recent FAA Modernization Efforts
The 2026 outage exposed a critical single point of failure in the FAA’s telecommunications network servicing one of the nation’s busiest air corridors. Both primary and backup fiber optic lines were compromised simultaneously, forcing controllers to suspend arrivals and slow traffic
through fallback spacing methods. This incident follows a 2025 pattern of radar and communications failures at FAA facilities, including previous disruptions at Philadelphia. In response to similar outages, Congress allocated approximately $12.5 billion in 2025 toward aviation infrastructure modernization aimed at replacing aging automation and telecommunications systems. Despite the Federal Aviation Administration’s efforts to consolidate radar data services and pilot advanced programs like the AI-driven Strategic Management of Airspace, Routes, and Trajectories (SMART) system—which coincidentally began rollout the same day—the incident underscores vulnerabilities in the underlying physical telecommunications infrastructure.
