US Flight Disruptions Persist After FAA System Outage
According to the International Desk of Webangah News Agency, a significant outage within the Federal Aviation Administration’s (FAA) communication systems has led to widespread flight disruptions across the United States, prompting a cascade of cancellations and delays affecting thousands of passengers. European air traffic control organization Eurocontrol confirmed it had suspended flights to the U.S. at the request of the FAA. Similarly, Mexico’s Federal Civil Aviation Agency stated it had received a request from its U.S. counterpart to halt departures to the United States.
Major airlines were quick to react. Air Canada announced the cancellation of all its flights between Canada and the U.S. until Friday evening. JetBlue Airways also reported the cancellation of all remaining flights from New York’s John F. Kennedy and Boston airports, with the exception of those bound for Europe. Delta Air Lines confirmed that the FAA’s order to halt all outbound flights nationwide remained in effect.
The disruption extended beyond air travel, with Amtrak, the U.S. national rail operator, reporting issues with its website and application. Airspace Intelligence, a company collaborating with the FAA on artificial intelligence development, stated that its software was not the cause of the flight stoppages.
The FAA attributed the nationwide grounding of outbound flights to an unspecified disruption in its communication systems. The agency indicated that as navigation facilities gradually returned to operational status, departures would be authorized in coordination with the Air Traffic Control System Command Center. CNN, citing a source, reported that the disruptions affected not only air traffic control radars but also radio frequencies simultaneously. Another source informed CNN that the FAA had notified airlines that the communications outage stemmed from an issue with network routing equipment.
Data from flight tracking websites painted a stark picture of the impact. Flightradar24 reported that for over two hours, no flights departed from Chicago O’Hare International Airport. The Wall Street Journal, citing FlightAware data, indicated that more than 1,100 domestic flights were canceled and nearly 10,000 were delayed. The New York Times, referencing Flightradar24, noted that despite the ongoing nationwide flight halt order, some international flights were permitted to depart the U.S.
The number of canceled flights in the U.S. rapidly surpassed 3,000, according to the New York Times, citing FlightAware. The newspaper also reported over 370 flight cancellations scheduled for Saturday, a consequence of the ongoing aviation crisis. Flightradar indicated a significant reduction in the number of aircraft in U.S. airspace, falling below 700. By 7 p.m. Eastern Time, Flightradar spokesperson confirmed over 2,400 flights had been canceled, with the number steadily increasing. FlightAware reported over 10,000 flights within or to/from the U.S. experiencing delays, and the total number of cancellations reached 4,237. Flightradar24 reported over 5,000 flight cancellations, with the figure continuing to rise rapidly.
Chicago O’Hare International Airport bore the brunt of the cancellations, with 459 flights affected, followed by Atlanta and New York’s LaGuardia Airport. By 7:45 p.m. Eastern Time, close to 5,000 domestic flights had been canceled, the New York Times reported, citing FlightAware. While the FAA lifted the initial nationwide ground stop, flight delays persisted at numerous airports. Atlanta outbound flights experienced delays exceeding three hours, and Boston outbound flights saw an average delay of 26 minutes due to air traffic congestion, according to the FAA. Reagan National Airport in Washington, D.C., was slated to receive no diversions until 6 a.m. Saturday local time.
NBC reported, citing officials, that there were no indications of any connection between the FAA incident and recent disruptions to Microsoft’s services. A Microsoft spokesperson stated the company had no evidence suggesting the flight halt order was related to its recent service outages. Canada’s Minister of Transport declared the country’s readiness to provide full assistance to the U.S. aviation authorities, including accepting aircraft if necessary.
U.S. government investigations, involving security and intelligence agencies, have so far yielded no evidence of an intentional attack, a security source told CNN. These investigations included a thorough assessment of the communication pathways of the U.S. aviation system and potential vulnerabilities to malicious intrusion. The source indicated that while officials still consider a software defect a possibility, no evidence of deliberate action has emerged. The New York Times, quoting several U.S. officials, reported no current signs pointing to a malicious cyber incident or other harmful activity as the cause of the communication disruption.
However, a security source informed CNN that security agencies are expected to continue their efforts in the coming days to identify any potential points of intrusion into the aviation system, as some cyber threats may only become apparent after deep network analysis. U.S. officials emphasized to the New York Times that the current assessment of the communication outage’s cause could change with the acquisition of new information.
Communication services at some FAA air traffic control facilities are gradually being restored, sources familiar with the matter told The Wall Street Journal. Fox News reported, citing the FAA, that the agency has begun the process of gradually lifting restrictions and resuming normal aviation activities as systems come back online. While the lifting of restrictions has commenced, some delays and cancellations across the U.S. are still anticipated, a source told Fox News. This source also reported that some flights bound for destinations outside the U.S., including Germany and Prague, have received clearance to depart. San Francisco International Airport announced that flights bound for trans-Pacific destinations have once again been authorized to take off.
