NEW YORK (AP) — The world’s largest aircraft fleet was grounded for hours by a cascading outage in a government system that delayed or cancelled thousands of flights across the U.S. on Wednesday.
The White House initially said that there was no evidence of a cyberattack behind the outage that ruined travel plans for millions of passengers. President Joe Biden said Wednesday morning that he’s directed the Department of Transportation to investigate.
Whatever the cause, the outage revealed how dependent the world's largest economy is on air travel, and how dependent air travel is on an antiquated computer system called the Notice to Air Missions System, or NOTAM.
Before commencing a flight, pilots are required to consult NOTAMs, which list potential adverse impacts on flights, from runway construction to the potential for icing. The system used to be telephone-based, with pilots calling dedicated flight service stations for the information, but has moved online.
The NOTAM system broke down late Tuesday, leading to more than 1,000 flight cancellations and more than 6,000 delayed flights by 11 a.m. Wednesday, according to the flight tracking website FlightAware.
The chaos is expected to grow as backups compound. More than 21,000 flights were scheduled to take off in the U.S. today, mostly domestic trips, and about 1,840 international flights expected to fly to the U.S., according to aviation data firm Cirium.
Longtime aviation insiders could not recall an outage of such magnitude caused by a technology breakdown. Some compared it to the nationwide shutdown of airspace after the terror attacks of September 2001.
“Periodically there have been local issues here or there, but this is pretty significant historically,” said Tim Campbell, a former senior vice president of air operations at American Airlines and now a consultant in Minneapolis.
Campbell said there has long been concern about the Federal Aviation Administration’s technology, and not just the NOTAM system.
“So much of their systems are old mainframe systems that are generally reliable but they are out of date,” he said.
John Cox, a former airline pilot and aviation safety expert, said there has been talk in the aviation industry for years about trying to modernize the NOTAM system, but he did not know the age of the servers that the FAA uses.
He couldn’t say whether a cyberattack was possible.
“I’ve been flying 53 years. I’ve never heard the system go down like this,” Cox said. “So something unusual happened.”
According to FAA advisories, the NOTAM system failed at 8:28 p.m. Eastern on Tuesday preventing new or amended notices from being distributed to pilots. The FAA resorted to a telephone hotline to keep departures flying overnight, but as daytime traffic picked up it overwhelmed the telephone backup system.
The FAA ordered all departing flights grounded early Wednesday morning, affecting all passenger and shipping flights.
Some medical flights could get clearance and the outage did not impact any military operations or mobility.
Flights for the U.S. military’s Air Mobility Command, were not affected.
Biden said Wednesday morning that he was briefed by Transportation Secretary Pete Buttigieg.
“I just spoke to Buttigieg. They don’t know what the cause is. But I was on the phone with him about 10 minutes,” Biden said. “I told him to report directly to me when they find out.
Julia Macpherson was on a United Airlines flight from Sydney to Los Angeles on Wednesday when she learned of possible delays.
“As I was up in the air I got news from my friend who was also traveling overseas that there was a power outage,” said Macpherson, who was returning to Florida from Hobart, Tasmania. Once she lands in Los Angeles, she still has a connection in Denver on her flight to Jacksonville, Florida.
She said there have been no announcements on the flight about the FAA issue.
Macpherson said she had already experienced a delay in her travels because her original flight from Melbourne to San Francisco was canceled and she rebooked a flight from Sydney to Los Angeles.
Similar stories came out of Chicago, Washington, Atlanta and other major U.S. airports.
European flights into the U.S. appeared to be largely unaffected.
Irish carrier Aer Lingus said services to the U.S. continue, and Dublin Airport’s website showed that its flights to Newark, Boston, Chicago and Los Angeles were running on schedule.
“Aer Lingus plan to operate all transatlantic flights as scheduled today,” the carrier said in a prepared statement. “We will continue to monitor but we do not anticipate any disruption to our services arising from the technical issue in the United States.”
It was the latest headache for travelers in the U.S. who faced flight cancellations over the holidays amid winter storms and a breakdown with staffing technology at Southwest Airlines. They also ran into long lines, lost baggage, and cancellations and delays over the summer as travel demand roared back from the COVID-19 pandemic and ran into staffing cutbacks at airports and airlines in the U.S. and Europe.

NEW YORK (AP) — Thousands of flight delays and cancellations rippled across the U.S. early Wednesday after computer outage led to a grounding order for all departing aircraft by the Federal Aviation Administration.
The FAA is working to restore what is known as the Notice to Air Missions System.
Before commencing a flight, pilots are required to consult NOTAMs, or Notices to Air Missions, which list potential adverse impacts on flights, from runway construction to the potential for icing. The system used to be telephone-based, with pilots calling dedicated flight service stations for the information, but has now moved online.
While the White House initially said that there is no evidence of a cyberattack, President Joe Biden said “we don’t know” and told reporters that he’s directed the Department of Transportation to investigate the cause of the disruption.
The FBI did not immediately respond to a request seeking comment.
The stop order was lifted just before 9 a.m., but delays and cancellations are expected to snowball. Departure gates at major airports are filled with aircraft that had been ordered grounded for hours. More than 21,000 flights were scheduled to take off in the U.S. today, mostly domestic trips, and about 1,840 international flights expected to fly to the U.S., according to aviation data firm Cirium.
More than 4,300 flights were delayed and more than 800 were cancelled by around 9:30 a.m.
The stop order by the FAA impacted almost all flights of shippers and passenger airlines.
Some medical flights could get clearance and the outage did not impact any military operations or the mobility of U.S. defense forces.
Biden addressed the FAA issue Wednesday before leaving the White House to accompany his wife to a medical procedure at Walter Reed National Military Medical Center outside of Washington. He said he had just been briefed by Transportation Secretary Pete Buttigieg, who told him they still had not identified what went wrong.
“I just spoke to Buttigieg. They don’t know what the cause is. But I was on the phone with him about 10 minutes," Biden said. "I told him to report directly to me when they find out. Air traffic can still land safely, just not take off right now. We don’t know what the cause of it is.”
Buttigieg said in a tweet that he is in touch with the FAA and monitoring the situation.
Delays and cancellations that began on East Coast quickly spread west, with disruptions at almost all major U.S. airports.
The FAA said it was working on restoring its Notice to Air Missions System.
“We are performing final validation checks and reloading the system now,” the FAA said. “Operations across the National Airspace System are affected.”

NEW YORK (AP) — The Federal Aviation Administration is lifting a ground stop on flights across the U.S. following a computer outage early Wednesday that resulted in thousands of delays quickly cascading through the system at airports nationwide.
Earlier in the morning the FAA ordered all U.S. flights to delay departures until at least 9 a.m. Eastern. Due to heavy congestion, the FAA cleared flights to depart at Newark Liberty and Atlanta Hartsfield-Jackson airports. The agency said that normal air traffic operations were resuming gradually across the U.S. following the outage.
More than 3,700 flights were delayed and more than 640 were cancelled early in the day.
The FAA said that it continues to look into the cause of the initial problem.

NEW YORK (AP) — A computer outage at the Federal Aviation Administration brought flights to a standstill across the U.S. early Wednesday, with thousands of delays quickly cascading through the system at airports nationwide.
The FAA ordered all U.S. flights to delay departures until at least 9 a.m. Eastern. Due to heavy congestion, the FAA cleared flights to depart at Newark Liberty and Atlanta Hartsfield-Jackson airports and departures were expected to resume at other airports soon.
There were more than 3,700 flights delayed by 8:30 a.m. Eastern, more than all the delayed flights for the entirety of the previous day, according to the flight tracking website FlightAware. More than 640 have been cancelled.
Those numbers are likely to grow, and the groundings impact almost all aircraft, including shipping and passenger flights.
More than 21,000 flights were scheduled to take off in the U.S. today, mostly domestic trips, and about 1,840 international flights expected to fly to the U.S., according to aviation data firm Cirium.
Some medical flights can get clearance and the outage is not impacting any military operations or mobility.
Early Wednesday, flights for the U.S. military’s Air Mobility Command had not been impacted, said Air Force Col. Damien Pickart, a spokesman for Air Mobility Command is responsible for all the troop movement and supply flights, such as the C-17s that carry the president’s motorcade vehicles when he travels, but also all the flights that transport troops from one base to another. Air Mobility Command was working with the FAA on the issue.
While the White House initially said that there is no evidence of a cyberattack, President Joe Biden said “we don’t know” and told reporters he’s directed the Department of Transportation to investigate the cause of the disruption.

Most delays were concentrated along the East Coast, but were beginning to spread west. Inbound international flights into Miami International Airport continued to land, but all departures have been delayed since 6:30 a.m., said airport spokesman Greg Chin.
The FAA said it was working on restoring its Notice to Air Missions System.
“We are performing final validation checks and reloading the system now,” the FAA said. “Operations across the National Airspace System are affected.”
The agency said that some functions are beginning to come back on line, but that “National Airspace System operations remain limited.”
United Airlines said that it had temporarily delayed all domestic flights and would issue an update once it learned more from the FAA. American Airlines said that it was closely monitoring the situation.

NEW YORK (AP) — A computer outage at the Federal Aviation Administration brought flights to a standstill across the U.S. on Wednesday, with hundreds of delays quickly cascading through the system at airports nationwide.
The FAA ordered all U.S. flights to delay departures until 9 a.m. Eastern, though airlines said they were aware of the situation and had already begun grounding flights.
At 8 a.m. Eastern, there were more than 2,500 delayed flights within, into or out of the United States, according to the flight tracking website FlightAware, exceeding the number of all delayed flights on the previous day. More than 150 have been cancelled.
Those numbers are likely to grow.
More than 21,000 flights were scheduled to take off in the U.S. today, mostly domestic trips, and about 1,840 international flights expected to fly to the U.S., according to aviation data firm Cirium.
