While aircraft already in the air were permitted to continue to their destinations, the <strong>FAA<\/strong> noted that international flights arriving in the U.S. are being managed on a case-by-case basis as gates at major hubs reach capacity.<\/p>\n<p><strong>U.S. Transportation Secretary Sean Duffy<\/strong> confirmed that the issue stems from a telecommunications outage affecting the critical infrastructure used by air traffic controllers to manage en-route traffic. The outage forced several facilities into &quot;<strong>ATC Zero<\/strong>&quot; status, a designation meaning they were unable to provide air traffic control services due to the loss of both automation and radio frequencies.<\/p>\n<p><em>Market analysts suggest the financial impact on the airline sector could be significant<\/em>, particularly as the industry struggles to reset flight crews and aircraft positions for the weekend schedule. This event marks only the third time in U.S. history that a nationwide ground stop has been implemented, following the 2023 NOTAM system failure and the 2001 terrorist attacks.<\/p>\n<p>Security sources cited by <strong>CNN<\/strong> indicate that all aviation systems are currently undergoing a comprehensive review to ensure the integrity of the national airspace. While the <strong>FBI<\/strong> and <strong>Department of Homeland Security<\/strong> continue to monitor the situation, officials emphasized that passenger safety remains the top priority and that no timeline has been established for a full resumption of service.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Over 11,000 flights were delayed or canceled across the United States
