A Verizon fiber-optic cable was accidentally severed by a construction crew in New Jersey on September 21, 2026, disrupting backup telecommunications for FAA air traffic control and causing nationwide flight delays and cancellations. The incident followed a failure of the primary telecom circuit at the FAA’s Philadelphia Terminal Radar Approach Control (TRACON) facility, affecting major airports including Newark Liberty International Airport, Philadelphia International Airport, John F. Kennedy International Airport, and LaGuardia Airport.
Flight Delays and Cancellations at Major Airports
The communications failure led to more than 9,500 U.S. flights being delayed or canceled on that Monday. Newark Liberty International Airport canceled over 600 flights and delayed nearly
100 by 6 p.m., while Philadelphia International Airport canceled more than 200 flights and delayed over 400. Flights destined for Newark were diverted to airports such as Detroit Metropolitan Wayne County Airport and Washington Dulles International Airport, with more than 100 diversions occurring. Newark experienced approximately eight hours without arriving commercial flights.
Responsibilities and Official Statements
FAA Administrator Bryan Bedford reported the primary telecommunications circuit at Philadelphia TRACON failed first, and the backup fiber-optic line was found broken when the system attempted to switch over. NJ Transit confirmed its construction crew, working on the New Brunswick to North Brunswick rail project about 10 feet
from utility markings, accidentally cut the Verizon cable. Verizon stated their network was fully operational before the severing, denying responsibility for the incident but dispatched technicians to repair the damage. Transportation Secretary Sean Duffy emphasized the event as proof of the urgent need for FAA infrastructure funding.
Traveler Impacts and Airline Responses
The disruption caused significant flight delays and cancellations across the Northeastern airports, creating ripple effects nationwide. United Airlines waived change fees and offered extra pay to employees working at Newark to address staffing challenges. American Airlines also waived fees and permitted affected passengers to travel via alternate airports to lessen inconveniences. Passenger arrival
issues persisted for hours as the FAA restricted inbound flights while restoration worked on.
FAA Modernization and Infrastructure Context
The FAA is undertaking a $12.5 billion modernization effort, funded by Congress in July 2025, to replace aging air traffic control infrastructure including copper wiring with fiber-optic cables, 5G wireless, and satellite links. By May 2026, 2,560 of 5,170 outdated copper lines had been replaced, and as of August 2026, 63% of copper wiring had been upgraded. FAA Administrator Bedford stated the agency aims to eliminate the remaining outdated copper lines by September 2027 to reduce single points of failure such as those seen in the
recent incident.
