FOX 9 Minneapolis-St. Paul has drawn more than a million views in half a day with Sean Duffy's explanation of the nationwide flight halt: a router repeatedly trying to connect to the air traffic control network, disrupting the communications it was meant to support.
The transportation secretary describes maintenance at a remote FAA location to replace aging copper wiring with fiber. The reason for the upgrade was straightforward. "We have an incredibly old telecommunication system," he says.
What happened during that work is still under investigation. Duffy identifies two possibilities: an installation error or a faulty router. His account describes the router flooding the network with more than a thousand connection attempts every few seconds, interfering with aircraft communications and radar feeds. Officials halted departures as a safety precaution.
That distinction matters to the question in the video's title, "What caused the nationwide FAA ground stop? Transportation Secretary Sean Duffy explains". The clip offers an explanation of how the disruption spread, but not a final determination of why the equipment failed.
The Short's audience is far beyond the station's usual first-day reach for that format. FOX 9's full press conference is also drawing an unusually large audience, alongside its local reporting on recovery at Minneapolis-St. Paul International Airport and the Minnesota Golden Gophers' travel plans.
