Air traffic control officials have revealed details of what caused widespread disruption that affected thousands of passengers stuck at airports.
The National Air Traffic Services (NATS) previously said an initial investigation found the problems were caused by flight data which its system “didn’t understand” and “couldn’t interpret”.
And the organisation said, in a preliminary report released today, that it had confirmed the root cause of the issues – while repeating its apology and insisting safety was not compromised at any point.
A statement issued by NATS said a problem had been identified with a flight plan processing system called Flight Plan Reception Suite Automated – Replacement (FPRSA-R).

Hundreds of Ryanair passengers have been left ‘stranded’ on a Spanish island after a technical fault affected air traffic control.
“A small but important part of NATS’ overall air traffic control technical infrastructure, it was found to have encountered an extremely rare set of circumstances presented by a flight plan that included two identically named, but separate waypoint markers outside of UK airspace,” it said.
“This led to a ‘critical exception’ whereby both the primary system and its backup entered a fail-safe mode.

“In these circumstances, the system could not reject the flight plan without a clear understanding of what possible impact it may have had.
“Nor could it be allowed through and risk presenting air traffic controllers with incorrect safety critical information. On the day, the time taken to recover was driven by the need to identify the problem and the specific data, isolate and remove it in a controlled way, and then test it to ensure it could be returned safely into operation.”

It added that the scenario had never been encountered before across more than 15 million flight plans over the five years it has been in service.

Sky News readers have been sharing dramatic stories while they are stranded abroad waiting to finally be able to fly home.
“Steps have been taken to ensure the incident cannot be repeated,” the statement said.
Martin Rolfe, chief executive at NATS, said: “Keeping the sky safe is what guides every action we take, and that was our priority during last week’s incident.
“I would like to reiterate my apology for the effects it had on so many people, including our airline and airport customers. Incidents like this are extremely rare and we have put measures in place to ensure it does not happen again.”
The failure is estimated to have cost airlines £100m, according to the head of the International Air Transport Association (IATA), Willie Walsh.
More than 1,000 flights departing UK airports were cancelled due to the problems last week, data from aviation analytics company Cirium revealed.
MasterChef host Gregg Wallace has stepped down over allegations he made a series of inappropriate sexual comments on a range of programmes over 17 years.
Broadcaster Kirsty Wark is among 13 people who have made claims, with Wallace being investigated by MasterChef’s production company Banijay UK.
In an interview with the BBC, the Newsnight presenter, who was a celebrity contestant on MasterChef in 2011, claimed Wallace used “sexualised language”.
“There were two occasions in particular where he used sexualised language in front of a number of people and it wasn’t as if it was anyone engaged with this,” Wark said.
“It was completely one-way traffic. I think people were uncomfortable and something that I really didn’t expect to happen.”
Sky News has contacted Wallace’s representative for comment.
‘Fully cooperating’
Banijay UK said the complaints were made to the BBC this week by “individuals in relation to historical allegations of misconduct while working with Gregg Wallace on one of our shows”.
The company said the 60-year-old, who has been a co-presenter and judge of the popular cooking show since 2005, was “committed to fully cooperating throughout the process”.
“Whilst these complainants have not raised the allegations directly with our show producers or parent company Banijay UK, we feel that it is appropriate to conduct an immediate, external review to fully and impartially investigate,” the company said.
“While this review is under way, Gregg Wallace will be stepping away from his role on MasterChef and is committed to fully co-operating throughout the process.
“Banijay UK’s duty of care to staff is always a priority and our expectations regarding behaviour are made clear to both cast and crew on all productions, with multiple ways of raising concerns, including anonymously, clearly promoted on set.
“Whilst these are historical allegations, incidences brought to our attention where these expectations are not met, are thoroughly investigated and addressed appropriately.”
A BBC spokesman said: “We take any issues that are raised with us seriously and we have robust processes in place to deal with them.
“We are always clear that any behaviour which falls below the standards expected by the BBC will not be tolerated.
“Where an individual is contracted directly by an external production company we share any complaints or concerns with that company and we will always support them when addressing them.”
Previous investigation
Last month, Wallace responded to reports that a previous BBC review had found he could continue working at the corporation following reports of an alleged incident in 2018 when he appeared on Impossible Celebrities.
Wallace said those claims had been investigated “promptly” at the time and said he had not said “anything sexual” while appearing on the game show more than half a decade ago.
In an Instagram post following an article in The Sun newspaper, he wrote: “The story that’s hitting the newspapers was investigated promptly when it happened six years ago by the BBC.
“And the outcome of that was that I hadn’t said anything sexual. I’ll need to repeat this again. I didn’t say anything sexual.”
Alongside MasterChef, Wallace presented Inside The Factory for BBC Two from 2015.
Wallace has featured on various BBC shows over the years, including Saturday Kitchen, Eat Well For Less, Supermarket Secrets, Celebrity MasterChef and MasterChef: The Professionals, as well as being a Strictly Come Dancing contestant in 2014.
He was made an MBE for services to food and charity last year.
Recorded episodes of MasterChef: The Professionals featuring Wallace will be transmitted as planned, the PA news agency understands.
The Scottish government has announced that all pensioners in Scotland will receive a winter fuel payment in 2025/26.
The devolved benefit is expected to come into force by next winter and will help the estimated 900,000 people north of the border who were cut off from accessing the winter fuel payment which used to be universal.
Social Justice Secretary Shirley-Anne Somerville announced the news in a statement to the Scottish parliament on Thursday.
It comes after both the UK and Scottish governments earlier this year axed the universal winter fuel payment, except for those in receipt of pension credit or other means-tested benefits.
At Westminster, Chancellor Rachel Reeves claimed the decision was made due to financial woes inherited from the previous Conservative government.
Ms Reeves said the restriction would save the Treasury around £1.4bn this financial year.
The decision led to the Scottish government – which was due to take control over a similar payment through the devolved Social Security Scotland but has since announced a delay – to follow suit.

Two police officers have been served with misconduct notices after a teenager with autism escaped from a police car and died on the M5.
Tamzin Hall, from Wellington, was hit by a car on the M5 between junction 25 at Taunton and 24 at Bridgwater shortly after 11pm on 11 November and sustained fatal injuries.
She had been under arrest at the time and was travelling in an Avon and Somerset Police car which had stopped on the motorway, an inquest at Wells Town Hall heard on Tuesday.
Tamzin was being taken to custody when officers pulled over for “safety reasons”, the Independent Office for Police Conduct said.
She had been handcuffed with her hands in front of her and had an officer sat beside her, the IOPC added.
She fled the stationary marked police car on the northbound carriageway and died after she was hit by a car on the southbound carriageway.
In a statement the IOPC said the two officers from Avon and Somerset Police had been served misconduct notices for a “potential breach of their duties and responsibilities”.
Such notices advise officers their conduct is subject to an investigation, but does not necessarily mean any disciplinary proceedings will follow.
IOPC regional director David Ford said: “My thoughts and sympathies remain with Tamzin’s family and friends, and everyone affected by the tragic events of that evening.
“We have met with Tamzin’s family to offer our condolences and to outline how our investigation will progress. We will provide them with regular updates as our inquiries continue.
“Our investigation is in the early stages and we are working hard to establish the exact circumstances of what took place, from the time of Tamzin’s arrest, to how events unfolded a short time later on the M5.”
The IOPC began its investigation earlier this month and is looking into what contact the police had with Tamzin prior to her death, including their actions, decision-making and risk assessments of the situation, and whether these followed the relevant training and policies.
