US Federal Aviation Administration suspends all flights due to communication issues

The Federal Aviation Administration suspended all flights in the United States on Friday at approximately 22:00 CET due to communication issues. The suspension was issued for safety reasons and extraordinary circumstances. The order remained in effect for several hours until the suspension was lifted on Saturday at approximately 02:15 CET. At the time the Federal Aviation Administration issued the order, more than 3,500 aircraft were in the air. By the time the suspension was lifted, fewer than 400 aircraft remained in the airspace.

Impact and scale of the suspension

The disruption caused significant logistical challenges for travelers and airlines. According to FlightAware, the suspension resulted in nearly 7,000 canceled or delayed flights. Data from FlightRadar24 provided different figures, recording over 4,700 canceled flights and approximately 10,000 delayed flights. During the period of the suspension, international flights were to be handled on an individual basis. A source stated that the FBI is monitoring the situation.

While the disruption was widespread, preliminary reports from CNN suggest the incident was not a cyberattack. US Secretary of Transportation Sean Duffy stated that technical specialists from the Federal Aviation Administration are investigating the cause. Sean Duffy noted that the air traffic control system is extremely outdated and data transmission equipment was overloaded. The failure was described as a result of connecting new technologies to an existing system that could not handle the load.

Calls for modernization

The incident has reignited discussions regarding the funding required to upgrade national infrastructure. Sean Duffy requested $50 billion from Congress for air traffic control modernization, following a previous request for $30 billion. Sean Duffy stated that "The President has been asking Congress for a year to fully fund a new air traffic control system." Additionally, Secretary of Homeland Security Markwayne Mullin also called for the modernization of Federal Aviation Administration technological systems.

This event marks a significant disruption in American airspace. This is the first nationwide flight suspension since January 2023, when a Federal Aviation Administration computer system failed. The last flight suspension prior to the January 2023 event occurred after the September 11, 2001, terrorist attacks.
