Quick Summary

The FAA issued a rare nationwide ground stop on Friday for all domestic flights due to a major outage in its air communications system. Homeland Security Secretary Markwayne Mullin characterized the event as a telecommunication outage rather than a cyber or terrorist attack, though the duration of the order remains unspecified. This marks only the third time in history the agency has halted all flights, following instances in January 2023 and September 11, 2001. The disruption caused airline shares to drop, with American Airlines falling more than 2% and United falling 1.6% in after-hours trading.
