According to The Defiant, Sean Duffy denied that the FAA's artificial intelligence tools caused Friday's nationwide departures ground stop, attributing the incident instead to an overload of legacy telecommunications equipment. The report also noted that the FAA announced on November 10 the expansion of SMART to airspace covered by 22 air traffic control centers. While this represents Duffy's attribution of the cause, the timeline of the AI tool's expansion cannot be directly equated as the reason for the ground stop.
