The Federal Aviation Administration suspended departures nationwide on Friday, November 13, after data overloads crippled communication links across all 22 regional air traffic control facilities. Although departures were completely halted, over 3,500 airborne flights were safely managed toward landing, while emergency services and medical evacuations were permitted to continue operating. The ground stop was terminated at 8:15 p.m. ET, but airlines faced extensive logistical chaos attempting to recover displaced planes and crew members. Transportation officials warned that without a comprehensive modernisation of antiquated systems, similar national transit failures will inevitably recur.

For several hours on Friday, one of the world's busiest aviation networks came to a near standstill. Airports across the United States witnessed mounting delays, grounded departures and diverted aircraft after a communications failure forced the Federal Aviation Administration (FAA) to halt flight operations nationwide. Thousands of passengers were left stranded as airlines struggled to manage the disruption.
The FAA imposed the nationwide ground stop on November 13 after communications problems affected air traffic control centres across the country. Although aircraft already in the air were allowed to continue towards their destinations, departures remained suspended for more than four hours.
The shutdown, the second nationwide aviation stoppage of its kind since the September 11, 2001, attacks, affected an estimated 1.5 million passengers. More than 10,000 flights were delayed or cancelled, while hundreds were diverted.
The FAA lifted the restrictions at 8:15 pm ET. However, the disruption continued as airlines worked to reposition aircraft and crew. US Transportation Secretary Sean Duffy warned that similar incidents could happen again unless the country's ageing aviation infrastructure was overhauled.
