FAA ruled out foul play or artificial intelligence as the cause of Friday’s nationwide ground stop that stranded more than a million travelers. The agency said the disruption was the result of a system issue, not sabotage.
FAA Rules Out AI, Cyberattack in Nationwide Ground Stop
FAA Administrator Bryan Bedford apologized, stating there was zero evidence of wrongdoing or AI involvement. He emphasized the investigation found no malicious intent.
Bedford explained the ground stop followed 45 minutes of system instability, during which officials could not identify the root cause. The pause was intended to give engineers time to assess the malfunction.
He said the decision to hold aircraft on the ground was meant to relieve pressure on the airspace and reduce complexity while investigators continued their analysis. Bedford maintained the measure was necessary to protect safety.
Bedford asserted the “worst is behind us” and defended the sweeping measure as the right call. He added that the agency stands behind its decision.
Transportation Secretary Sean Duffy said investigators are examining whether contractor error or faulty equipment triggered the unprecedented shutdown. The probe will determine if human error or hardware failure was responsible.
Duffy noted the issue stemmed from routine L3Harris maintenance that switched telecommunication lines from copper to fiber, replacing aging copper wiring. He said the upgrades had been underway for decades.
He questioned whether the problem resulted from user error, installer error, or a faulty router, but emphasized no definitive conclusion has been reached. The investigation remains ongoing.
Duffy also dismissed cyberattack theories, saying systems restored once the work at the remote site was isolated, indicating the failure was internal. He reiterated that there was no evidence of foreign interference.
More than 4,000 flights were canceled and 13,000 delayed, with Atlanta, Chicago, Houston, New York and Dallas‑Fort Worth the hardest hit. Airlines expect to resume normal operations by Sunday evening.
