A U.S. air traffic control outage disrupted flights nationwide, forcing airlines to delay or cancel services and leaving passengers facing widespread travel disruption, according to the Financial Times. The disruption stems from a failure in the systems that manage U.S. airspace, though the report did not specify the number of flights affected or the outage's duration. The event matters because U.S. aviation underpins broader economic activity, and any control-system failure can cascade quickly across airline schedules and hub airports. What to watch next is how quickly the Federal Aviation Administration restores full capacity and whether carriers report material financial hits from delays and cancellations.
