Overview
- The FAA ordered a nationwide suspension of all departing flights on Friday after regional air‑traffic communications showed inconsistent data and controllers lost reliable links, a step taken to keep airborne aircraft safe while ground departures were held.
- Officials said the primary problem was overloaded, decades‑old communications equipment such as routers and analog links, and reporting has identified a possible restart of a private L3Harris network during maintenance as a proximate trigger under investigation.
- The ground‑stop was lifted late Friday evening and U.S. airspace was reopened, but airlines and the FAA warned that reactivation would be gradual and that a large backlog of thousands of delays and cancellations would persist through the weekend.
- The White House and the Department of Transportation formally requested roughly $30.1 billion from Congress to accelerate replacement of air‑traffic control systems, control towers, and airport infrastructure while federal probes continue and the FBI and DHS report no evidence so far of a malicious cyberattack.
- The incident is the third national ground‑stop since 2001 and highlights how old communications wiring and interconnected systems can cascade into widespread travel and cargo disruption, risking longer passenger delays before holiday travel and adding pressure for faster, accountable modernization.
