US flight chaos: Hundreds of flights canceled at US airports after cable cut during construction

A severe communications failure on Monday led to widespread flight disruptions across the US Northeast, particularly affecting major hubs in New York and Boston. The incident originated from a failure in the primary circuit at Philadelphia air traffic control, alongside a severed backup line. Consequently, thousands of flights experienced delays or cancellations, leaving many passengers stranded, with only gradual return to normalcy in air travel operations.
