Faulty equipment in an “incredibly old” telecommunication system may have caused an air traffic control issue, U.S. Transportation Secretary Sean Duffy says.
In a press briefing on Saturday, he said a contractor was doing routine maintenance to upgrade copper wire to fibre optic cable when something went wrong.
Officials are now investigating whether the error was due to “incompetence” or a “faulty router,” he added.
U.S. officials said on Saturday that the effects of the stop could be felt for days, adding that the system will likely be operating normally in time for the U.S. Thanksgiving travel rush.
This is just the second nationwide ground stop in the United States since the Sept. 11, 2001, attacks.

Delays may continue: NAV Canada
NAV Canada says it will continue working to keep air traffic moving in Canadian airspace after the FAA lifted the ground stop order.
“Some delays may continue while operations return to normal and backlogs are cleared,” NAV Canada said in a post on social media.
It reiterated that passengers should check their flight status with their airline.
The systems were ‘overwhelmed’
In the Q&A following the press meet, U.S. Transportation Secretary Sean P. Duffy told reporters that the FAA had deployed their smart system to better navigate weather and trajectories for flights. But the system that was to blame for the disruptions was not connected to it.
“Smart had zero impact on the occurrences yesterday,” he said.
U.S. FAA Administrator Bryan Bedford told reporters that “nothing went down.”
“What we saw was instability. We couldn’t explain the instability. We saw the instability start to propagate into facilities we couldn’t identify,” he said. “That’s when we made the decision to ground stop out of our abundance. No facilities went dark. Nothing was fully boxed.”
Bedford added that the pressure “overwhelmed one set of routers in an in-facility, which then went through the backups at other facilities, and it propagated from there.”

‘Zero evidence’ of nefarious or AI-related issues
In the same press conference, U.S. FAA Administrator Bryan Bedford told reporters that the system had started displaying “instability” which they were unable to access, at which point they implemented the ground stop.
“We did that because we felt it was helpful to remove pressure from the system… holding airplanes on the ground while we continue to work through the root cause analysis of the instability in the system, and ultimately to relieve stress and complexity in the airspace,” he said.
Bedford added that at the time of the ground stop, nearly 30,000 flights were either on the ground or in air, and 20,000 remained. The FAA was ultimately able to recover only around 8,000 of those flights.
“I do think the worst is behind us, but we still do have a significant amount of recovery work to do with our airline stakeholder group,” the FAA administrator said, adding that they have identified the fault and had “zero evidence” of any nefarious or AI-related activities.

A few days to destination: Expert
Speaking to CP24, aviation management expert John Gradek said the disruption would take several days to unwind and reach back to normal.
While some flights might resume normal operations today, passengers whose trips were cancelled could wait until Monday, Tuesday, or Wednesday for available seats, he said.
He estimated around a million passengers were affected and explained that airlines must use “optimization and re-optimization” to get the right crews and aircraft to the right places in the right order.
“It does require a lot of calculations and a lot of mathematics to make sure that you get the right crews on the right airplanes at the right time at the right place,” he said.

Not a cyberattack: Duffy
U.S. Transportation Secretary Sean P. Duffy told reporters that they don’t believe it was a cyberattack from any foreign nation or otherwise.
“Once we were able to isolate the work that was being done at this remote location, all of our systems came back online,” he said. “So, we don’t believe this was cyber at all, this was an FAA system that didn’t meet the moment.
“Our contractor didn’t meet the moment, or the equipment didn’t meet the moment and caused the outages,” Duffy added.
The U.S. FAA is working toward “modernizing air traffic control,” the U.S. transportation secretary said, adding that the resources provided are not enough.

Work to replace old copper wiring to blame?
U.S. Transportation Secretary Sean P. Duffy told reporters Saturday that there was an issue with an old copper wire in “an incredibly old telecommunication system,” which was being replaced, that caused the disruption in the flight radar feeds.
“In at least one of our remote FAA locations, a contractor was doing routine maintenance to switch telecommunication lines from old copper wire, and they were bringing it over to fiber,” Duffy said.
“The work happening was due to the age of the copper wire that we were replacing. It was such an old wire that it was being discontinued, meaning that line was going to get shut down,” he continued.
The U.S. transportation secretary added that the U.S. FAA may have been the last one to be making this switch from copper to fibre due to lack of investments.
“What we’re working to determine was whether we had incompetence: meaning was it user error or installation error from L3 Harris (the contractor), or did they install a faulty router? We haven’t determined what the fault was,” Duffy said.
“Either through contractor error or a faulty piece of equipment, the router that was being replaced as we switched from copper to fiber… it started flooding other routers in our air traffic control system.”

40 flights cancelled at Montreal-Trudeau International Airport
The Montreal-Trudeau International Airport said 40 flights were cancelled Saturday as operations resumed after a Federal Aviation Administration (FAA) ground stop temporarily suspended flights on Friday.
Airport authorities said airlines resumed flights to the U.S. after the FAA lifted the temporary suspension of flights after 9 p.m.
“Aircraft that were unable to land in Montreal yesterday cannot depart today, which explains these cancellations,” a Montreal airport spokesperson told CTV News Saturday.
“We encourage travelers to check the status of their flight with their airline before heading to the airport.”
On Friday, 61 flights were cancelled, including 32 arrivals and 29 departures, as a result of the ground stop.

Operations ‘slowly’ returning: Duffy
U.S. Transportation Secretary Sean Duffy says flight operations are “slowly returning to normal” as of Saturday morning.
In an X post, he added that there will still be some delays and cancellations as carriers “reschedule flights and reposition” aircraft and crews.
“Our top priority right now is making sure travelers get home safely to their families as quickly as possible,” the post reads.
He added that officials will share more updates at 10:30 am ET this morning.
Airlines not required to offer additional compensation
An FAA computer problem is considered outside the control of the airlines — much like the weather.
The only thing the airlines are obligated to do is to offer free rebooking on another flight for travellers that want to continue to their destinations or a refund if their flight was canceled and they decide not to take the trip.

Mexican singer stranded after Latin Grammys
Singer-songwriter Vivir Quintana was stuck in Las Vegas the day after performing at the Latin Grammys, upending plans to return to Mexico City for a performance Friday evening.
She was supposed to join Majo Aguilar as a guest artist for their performance at the country’s national auditorium.
“We’re waiting for our suitcases — hopefully this can get resolved — but right now, all we can really do is breathe and be patient,” she said. “She’s performing there for the first time tonight — her very first time at the auditorium. My family will be there, so I’m sad about that.”
Flight disruptions to continue: Pearson
Toronto Pearson International Airport says U.S. flights will continue “to experience disruptions and cancellations as airlines work to restore normal flight schedules,” despite the ground stop order being lifted.
The airport is advising passengers to keep checking the status of their flight directly with their airline before travelling to the airport.
No guarantee scenario won’t repeat itself: Duffy
“Is this exact thing going to happen again?” U.S. Transportation Secretary Sean Duffy told reporters. “I don't—I don’t know that this exact scenario will happen.”
Duffy also repeatedly called on Congress to authorize billions of dollars in spending to modernize federal aviation safety.
“And so I would say, America, Congress, let’s make this system more safe,” Duffy said.
Getting planes back in air will take time: official
At the time of the ground stoppage, there were 3,500 airplanes in the sky.
“And last time I looked, we had less than, 400 in the airspace,” said U.S. Transportation Secretary Sean Duffy.
“It’s going to be slow” getting air traffic back to normal, he added.
Ground stop strands Toronto couple
Toronto-area couple Lyle Jakobsen and his wife were supposed to fly back from Sint Maarten this afternoon when their Air Canada flight got cancelled.
“We boarded. Everything was fine. In probably 10 minutes after boarding, we got a notification that we would be delayed. There was the FAA issue, so we sat on the tarmac for, I would say, probably the better part of an hour and 15 minutes,” Jakobsen told CP24 on Friday night.
“The pilot kept us up to date while we were on the tarmac.”
Passengers were then deboarded, and Jakobsen said he was able to find a hotel where they could stay.
Air Canada has said that flights from the Caribbean and South America that have to pass through U.S. airspace would be impacted by the ground stop.
“Air Canada has been very communicative with us, and we’re happy with that for sure. So, what one more night in Saint Martin is probably not the worst scenario,” Jakobsen said, adding that he hopes that they get to fly back to Toronto tomorrow.

Barbados flight ‘indefinitely cancelled’: traveller
A traveller who was set to fly out of Barbados to Toronto said she got the news her flight was cancelled when her plane was on the runway ready for take off.
Dominique Franklin spoke to CTV News Channel on Friday, sharing how she is stuck in Barbados as a result of the FAA grounding flights in U.S. airspace.
The flight crew said they were unable to access radar and radio to safely fly the plane, Franklin reported.
“I went straight to the WestJet desk,” she said, after she and her co-passengers left the plane.
“The only update that they were able to give us is to really just keep checking your email and we hope to be out to Toronto tomorrow morning.”
Franklin says she will sleep in half-hour increments tonight so she can check her email.
No evidence of cyberattack: DHS
“There was never any lives at risk,” U.S. Homeland Security Secretary Markwayne Mullin said. “There was no flights at risk. FAA was able to handle it. We did it out of an abundance of caution.”
Mullin sought to downplay conspiracy theories about what caused the outage.
“I do understand the internet traffic, and where all these conspiracies are running towards,” he said.
Ottawa updates U.S. travel advisory
The federal government updated the safety and security section for the United States on its travel advisory website Friday.
It states that the FAA issued a nationwide ground stop for all U.S. airports, and that travellers can “expect air travel disruptions.”

Pearson Airport provides update on non-U.S. flights
Toronto Pearson Airport says international and domestic flights that do not require transit through the U.S. airspace will continue to operate.
“We are increasing staffing across the airport to assist affected passengers. Our support teams are being deployed throughout the terminals, with additional resources available in the U.S. departures area,” Pearson said in a post on social media.
“We are also working closely with airlines and have implemented a parking plan for aircraft.”
More than 100 flights to and from the U.S. have already been cancelled at Pearson tonight.
Communication issues don’t appear linked to new FAA system
The communications problems that led to the nationwide halt to flights don’t appear to be linked to the FAA’s new AI-powered system the agency is rolling out to help predict problems in the sky.
The FAA’s SMART system is based in a single location near Washington, D.C., where a team of experts analyzes flight schedules, weather forecasts and hundreds of other streams of data.
Then that office sends recommendations to the FAA’s command centre that relays them to controllers across the country for consideration.
The company that designed the system, ASI, said “the current ground stop is not based on or a result of the SMART system, any product of ASI or our integration with FAA and ATC.”

U.S. ground stop throws sports world into chaos
The FAA's decision to ground all flights nationwide Friday threw the sports world into chaos, leaving NBA and NHL teams stranded as they tried to reach their destinations, and NFL teams were left to wonder whether the issue would be resolved in time for them to travel to their games this weekend.
The Nets were among five NBA teams scheduled to fly Friday for games on Saturday. They had just boarded the team plane in New Orleans after playing the Pelicans earlier this week when their flight to Memphis was halted in place.
The Pistons flew earlier in the day to Miami. The Cavaliers, Bulls and Grizzlies play Friday night and were due to fly afterward.
There are 14 scheduled games in the NHL on Saturday. And while the Panthers made it to St. Louis for their game before the stoppage began, the Sharks were among those that were left waiting to leave for their game in Utah.
The FAA did not provide a timeline for restarting flights, leaving sporting events taking place beyond Saturday in limbo. That includes most of the Week 10 schedule in the NFL.
Caribbean, South America flights may be affected: Air Canada
Yasmine Mehdi, an Air Canada spokesperson, said the ground stop is affecting flights to and from the United States. She said flights to and from the Caribbean and South America may also be affected.
"Any flights currently airborne have been advised they are permitted to continue," said Mehdi. "We are monitoring the situation very closely and will provide updates as they become available."

‘Traffic management measures’ at Canadian airports
NAV CANADA, the country’s air navigation authority says it is “implementing traffic management measures” at major airports as a result of the FAA grounding U.S. flights.
The measures will help manage traffic at Toronto Pearson International Airport (YYZ), Montréal-Pierre Elliott Trudeau International Airport (YUL), Calgary International Airport (YYC) and Vancouver International Airport (YVR), the agency said in a post on X.
“Travellers should expect delays and check with their airline,” NAV CANADA added.
Pilots trained how to handle losing communications: expert
Aviation professor Skip Bailey said the reason they teach them that is so they will be prepared if the radio on their plane malfunctions. He said no one expects air traffic controllers nationwide to lose the ability to communicate.
Pilots are expected to maintain the headings and vectors that controllers gave them before the problem. And then if the outage continues, they revert to following their filed flight plan. Pilots may also be able to communicate with each other over the radio even if they can’t talk to controllers. And airliners have their own radar systems.
“It’s not mass chaos out there. There’s plenty of ways to try to communicate,” said Bailey, who teaches at the University of Nebraska at Omaha’s aviation institute. “But not letting anybody take off again obviously is extremely important because we don’t want to put more aircraft into a system that’s already having an issue.”

Pearson passengers wait for flight updates
A number of passengers flying to the U.S. at Toronto Pearson Airport are still waiting for updates from their airlines about their flights.
Donna, who is flying to New York City for the weekend, says her flight has been rescheduled for tomorrow.
“I was really hoping to fly out tonight. So, it’s a bit of an unfortunate situation,” she told CP24.
“Definitely very disappointed that my plans for the weekend have been cancelled, or at least very delayed.”
Derek is supposed to fly to Las Vegas and says Air Canada has told him to “stick around.” However, he is not optimistic that he’ll get to his destination.
“It’s most likely going to be cancelled. And even if you’re rebooked till tomorrow, it’s unlikely. So, I think you’re going to have people with a lot of refunds,” Derek said.
Shahab Mirmiran came to Toronto on Monday for work and is hoping to get back to Los Angeles tonight.
"Unfortunately, we don’t know what’s going on. I have to go. I need to do something for work,” he said. “They’re just saying you have to wait.”
Another man who arrived from London, U.K., says he's waiting to hear about his connecting flight to Raleigh, N.C.
“It stinks, but just holding off for a little bit and seeing what happens,” he said.

‘Canadian systems are operating normally’: minister
Transport Minister Steven MacKinnon confirmed on Friday that Canada’s air traffic systems are running as expected.
“Canadian systems are operating normally,” he said in a post on X, adding that he is in contact with NAV CANADA.
However, he advised that travel to the U.S. may be disrupted.
“We will continue to monitor developments as the situation evolves and remain in contact with the relevant authorities.”
More than two dozen U.S. flights to and from Pearson cancelled
According to Toronto Pearson Airport’s website, as of 5:30 p.m. ET, about 14 flights to a number of U.S. destinations, including Newark, Boston, Chicago, and Seattle, have been cancelled.
Meanwhile, at least 26 American flights scheduled to arrive at Pearson tonight have also been cancelled.
Vancouver braces for delays
Vancouver International Airport says travellers heading to the U.S. should expect interruptions amid the FAA’s nationwide ground stop.
YVR is seeing delays for U.S.-bound departures, as well as “some international flights that would fly over the U.S.," the Richmond, B.C.-based airport says in a notice online Friday.
“Domestic flights within Canada are not impacted,” the airport adds.
“We recommend travellers check their flight status with their airline or yvr.ca before coming to the airport.”
No sign grounding triggered by threat: DHS Secretary
U.S. Homeland Security chief Markwayne Mullin on Friday said there was no indication of a threat to the country after a ground stop was issued at airports nationwide.
“There was no indication, as of yet, that this was a nefarious attack against us, it’s just a telecommunication outage, as of right now,” Mullins said, adding officials were “not ruling out anything at this point.”
‘Every flight has been accounted for’: FAA
The FAA says every flight has been accounted for and international flights will “be handled on a case by case basis.”
In a social post on the agency’s X account, the FAA said the call to halt all flights was made “out of an abundance of caution” due to a “temporary telecommunications outage.”
Issue appears similar to September outage: expert
Former United Airlines pilot and aviation expert Steve Arroyo said the problem appeared similar to a regional air traffic control communication outage in September that snarled hundreds of flights across the Northeast, except this time on a nationwide scale.
Arroyo said it could be linked to the outdated technology used by air traffic controllers.
“If you don’t have that ability, whether it’s because the old wires that they have are just run down or for whatever reason, you’ve got to stop airplanes on the ground,” said Arroyo. “And not put them in the air where you’re going to risk not being able to communicate with them.”
