The United States lifted the ban on air travel after 4 hours.

Bangla Press Desk:  The U.S. Federal Aviation Administration (FAA) has lifted its nationwide ground stop on air traffic. The airspace was reopened at 8:15 p.m. local time on Friday (November 13), following disruptions to radar and communication systems that began at 3:36 p.m. Consequently, air traffic across the country resumed after a suspension lasting more than four hours.

According to reports from Reuters and the BBC, Duffy stated that instability had affected radar, communication systems, and control centers nationwide. The FAA issued the ground stop after routers began transmitting inconsistent data. He explained that the routers became overwhelmed by an excess of data, leading to malfunctions and the generation of unreliable information.

Duffy confirmed that the airspace was reopened at 8:15 p.m. local time, and that both FAA control centers and Terminal Radar Approach Control (TRACON) facilities are now operational. However, he noted that it would take some time to resolve the complications caused by the afternoon's events, and that air travel could remain affected for the next few days. Flights scheduled for this weekend are also being reviewed to help normalize the situation.

He pointed out that the U.S. air traffic control system is significantly outdated, noting that the routers became unstable under the pressure of excessive data. He urged Congress to allocate $50 billion to modernize the system. Currently, both chambers of the U.S. Congress are controlled by the Republican Party.

Meanwhile, Markwayne Mullin, a member of the House Committee on Homeland Security, informed reporters that the nationwide ground stop was not the result of a cyberattack. He also clarified that the incident is unrelated to the recent service disruptions experienced by Microsoft.
Earlier, three sources indicated that the outage was linked to issues within a critical FAA communication network managed by the defense and technology firm L3Harris. However, Duffy stated that the incident did not result in a complete failure of communication systems or radar capabilities.

The disruption led to the grounding of thousands of flights, leaving countless passengers stranded. Kathy Eiserman-Boram, a retired teacher, faced difficulties due to the situation at Newark Liberty International Airport in New Jersey. She explained that her flight had been cancelled yesterday because of adverse weather, and it was cancelled once again today following the nationwide order to halt all flight departures.
