A significant technical glitch in the US Federal Aviation Administration's (FAA) communication systems led to an unprecedented halt in air traffic across the United States on Friday. The FAA suspended all flight departures for over four hours due to "exceptional circumstances" related to a communication problem affecting all air traffic control centers.
The incident had far-reaching consequences, causing over 8500 flight delays and nearly 8000 cancellations, according to data from FlightAware. At the time of the suspension, over 3500 aircraft were airborne in US skies, with some diverted to alternative airports and others continuing to their destinations.
The FAA lifted the suspension at 20:15 Eastern US time, allowing some flights to resume, including those from San Francisco International Airport. However, the disruptions extended beyond domestic flights, impacting international travel as the European Organisation for the Safety of Air Navigation, Eurocontrol, suspended flights to the US due to technical issues.
The effects of the glitch were felt globally, with Sydney Airport halting US-bound flights and Air Canada cancelling several flights between the US and Canada. US Transportation Secretary Sean Davey warned that the aftermath of the incident would persist for several days, with efforts underway to reorganize air traffic and address the disruptions.
Airlines began gradually resuming operations, with Delta Air Lines, United Airlines, and American Airlines working to operate as many flights as possible. JetBlue announced plans to restart operations on Saturday. Under US law, airlines are required to provide alternative travel arrangements or full refunds for cancelled or significantly delayed flights.
The incident highlighted the need for an overhaul of the US air traffic control system's infrastructure, which is estimated to require $50 billion in upgrades. US Homeland Security Secretary Marcuoine Mullin stated that there was no evidence of a cyberattack, but rather a technical issue caused by introducing new technology into an outdated system.
The FAA's communication system, which has been in use for many years, was overwhelmed by data, leading to network and router failures that affected communication and radar systems. The incident marked the second nationwide halt in flight departures since the 9/11 attacks in 2001, with experts describing it as one of the most significant disruptions in recent US aviation history.
