On Monday, a construction crew in New Jersey accidentally severed a critical fiber-optic cable, cutting both a primary and backup data feed for air traffic controllers. This failure at the Philadelphia TRACON facility led to ground stops and widespread disruptions across the Northeast, resulting in over 1,000 cancellations and 6,000 delays nationwide.
The outage affected major hubs such as Newark Liberty International, JFK, LaGuardia, and Philadelphia airports, as well as Teterboro and airports in Boston. The FAA diverted approximately 100 planes, including some arriving from Europe, during a window when over 100 global leaders were traveling to New York City for the U.N. General Assembly.
