Hundreds of US flights cancelled due to outage

## Major Flight Cancellations in the Northeast

A significant telecommunications outage led to the cancellation and delay of hundreds of flights at major airports along the US East Coast. The disruption occurred on Monday when an Amtrak construction crew accidentally severed a fiber optic line in New Jersey, impacting communication systems crucial for air traffic management.

## Impact on Key Airports

The incident affected several major airports, including Newark, LaGuardia, JFK, and Philadelphia. As of 1900 GMT, Newark Airport reported 168 flight cancellations and 97 delays, while Philadelphia experienced 63 cancellations and 189 delays. Flights at LaGuardia and Philadelphia began resuming around this time, but operations at Newark and JFK remained paused.

## FAA Response and Recovery Efforts

Bryan Bedford from the Federal Aviation Administration (FAA) explained that the outage was compounded by a break in the backup fiber line, described as a massive rupture. The primary system was expected to be restored by early afternoon, but repairs to the backup line were anticipated to take approximately 13 hours.

Transportation Secretary Sean Duffy communicated updates via social media, indicating efforts were underway to resolve the issue and minimize disruptions. The incident highlights the vulnerability of critical infrastructure to construction-related mishaps, emphasizing the need for robust contingency planning in air traffic operations.
