The White House says it is investigating the Federal Aviation Administration (FAA) computer glitch that has caused all flights across the country to be grounded.
Operations in the United States are now finally starting to resume after all flights were grounded.
“Normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews,” the FAA said in a statement at 8:50 a.m. ET on Wednesday.
The agency’s Tuesday order for all airlines to ground planes in the United States was prompted by the failure of a key pilot notification system that’s operated by the FAA.
The agency’s Notice To Air Missions (NOTAM) system, which is critical for relaying essential information to flights, failed for the first time in history.
FAA officials said early Wednesday they were making progress in restoring the system.
“FAA has determined that the safety system affected by the overnight outage is fully restored,” Transportation Secretary Pete Buttigieg added later, in a statement at 8:54 a.m. ET.
That ground stop has been lifted, according to the FAA.
The agency had said the pause in domestic departures was to let the agency “validate the integrity of flight and safety information.”
While the grounding excluded military aircraft and medical evacuation flights, it impacted hundreds of commercial planes.
White House press secretary Karine Jean-Pierre announced in a statement on Twitter that President Joe Biden has been briefed on the outage.
She stated that there’s no indication the issue was caused by hackers.
“There is no evidence of a cyberattack at this point,” she said.
Jean-Pierre added that Biden directed the Department of Transportation “to conduct a full investigation into the causes,” she wrote.
Buttigieg said he directed “an after-action process to determine root causes and recommend next steps.”
United Airlines said in a statement that it has begun resuming flight operations and the company would be issuing travel waivers to people impacted by the ground stop.
American Airlines said in a statement it was working to minimize customer disruptions.
Meanwhile, Southwest Airlines urged travelers to check for any changes to flight status.
