FAA Orders Nationwide Ground Stop After Widespread Air-Traffic Communications Failure

Overview

• Federal Aviation Administration officials halted all U.S. flights on Friday as an emergency safety measure, citing “extraordinary circumstances” while controllers and technicians worked to restore communications.
• The stoppage produced major travel disruption with media reports citing more than 10,000 delays and over 1,700 cancellations by early evening.
• Homeland Security Secretary Markwayne Mullin told reporters the pause was not the result of terrorism and said investigators have not yet determined the root cause of the telecommunications failure.
• During a public briefing, Mullin interrupted a reporter to insist on using the administration’s preferred term “SI” for artificial intelligence, a moment that drew sharp criticism from progressive commentators and Democratic figures.
• Authorities continue technical and safety checks at air traffic control centers, and the probe’s findings will determine when flights resume and what steps are needed to prevent similar nationwide outages.
