All departing US flights grounded due to communication problem

On Friday, the Federal Aviation Administration (FAA) in the United States imposed a nationwide ground stop for all departing flights, citing a communication issue that affected air traffic control towers. This unprecedented move led to confusion among travelers worldwide. The agency stated that FAA technicians are currently investigating the root cause of the problem.

Similar orders have been issued in the past due to communication issues, typically lasting a few hours. However, system-wide groundings across the entire country are incredibly rare. In January 2023, the FAA had previously called for a nationwide ground stop due to problems with the Notice to Air Missions (NOTAM) system, which provides pilots with critical information about potential hazards, airport facility changes, and other flight-affecting information.

That outage only lasted under two hours, making it the first nationwide grounding since the 9/11 attacks. The order came on the same day that US Transportation Secretary Sean Duffy had formally requested $30.1 billion from Congress to upgrade and modernize the nation's air traffic control system. This investment is crucial to creating a resilient telecommunications backbone for air traffic controllers, providing modern hardware and software, state-of-the-art control towers, and world-class airport infrastructure, as per Duffy and Office of Management and Budget Director Russell Vought.
