   Construction cable cut causes flight delays and cancellations at major US airports

   Hundreds of US flights are canceled or delayed after construction workers accidentally cut a cable essential for air traffic control. The Federal Aviation Administration grounded planes at major airports for several hours, with significant disruptions concentrated across the Northeast. Philadelphia International Airport issued a ground stop due to an equipment outage, while Newark and Bradley International airports reported delays and backups. Transportation officials attribute the travel meltdown to the failure of an aging circuit and its corresponding backup system.

   Why it matters

   Air traffic control relies on redundant communication cables to maintain safety and coordination. A failure in both the primary circuit and backup system can force the FAA to halt takeoffs and landings to prevent mid-air collisions. This incident highlights vulnerabilities in the aging infrastructure of key US air traffic centers.

   What is confirmed

   • The FAA grounded planes at major airports for several hours.
   • Hundreds of US flights were canceled due to the outage.
   • Flight disruptions affected major airports across the US Northeast.
   • Philadelphia International Airport implemented a ground stop.

   Still unconfirmed

   • Construction workers accidentally cut a cable needed for air traffic control.
   • The travel meltdown was caused by an aging circuit and backup system failure.
