The Federal Aviation Administration issued an emergency nationwide ground stop on Friday, suspending every departing flight in the United States after a communications fault disrupted all Air Route Traffic Control Centers.
FAA officials said technicians are actively investigating the problem that crippled the network linking control towers to aircraft. The agency has previously issued localized grounding orders for individual airlines, typically lasting only a few hours, but a systemwide shutdown of this scale is rare.
The last comparable nationwide halt occurred in January 2023 when a failure in the Notice to Air Missions (NOTAM) system grounded flights for just under two hours.
Transportation Secretary Sean Duffy used the incident to reinforce a request to Congress for $30.1 billion to modernize the national air‑traffic system, emphasizing the need for a resilient telecommunications backbone, updated hardware and software, and state‑of‑the‑art control towers.
At Las Vegas’s airport, Southwest Airlines staff informed passengers that no departures would take place for the next 24 hours, leaving travelers uncertain about rebooking options.
The FAA’s statement highlighted that the current outage is being treated with the utmost urgency, and airlines are cooperating to minimize passenger inconvenience while the technical issue is resolved.
Industry observers note that the incident underscores long‑standing concerns about aging infrastructure, reinforcing the urgency of the funding request outlined in Duffy’s letter to lawmakers.
