Andy Burnham Refuses to Back Air Traffic Control Boss as He Demands Full Investigation into Flight Chaos
Prime Minister Andy Burnham has refused to publicly back the chief executive of Britain’s air traffic control provider after a fresh technical failure caused widespread disruption at airports across the country. The latest incident has intensified scrutiny of National Air Traffic Services (NATS) and raised new questions about the resilience of the systems responsible for managing Britain’s airspace.
The disruption on September 21 came less than two weeks after a separate NATS failure caused more than 2,000 flight cancellations and affected hundreds of thousands of passengers. Although the two incidents are understood to have different technical causes, their close timing has prompted renewed criticism from airlines, airports and political figures.
Burnham has called for a full investigation into what happened, while NATS chief executive Martin Rolfe faces renewed pressure from parts of the aviation industry to resign. Unlike the government’s position earlier in September, when Downing Street said it retained confidence in Rolfe, Burnham has now declined to offer the same explicit backing following the latest disruption.
A Second Major Failure in Just Two Weeks
The latest problems began at the NATS control centre at Prestwick in Scotland. A technical issue affected air traffic passing through Scottish airspace and parts of the North Atlantic, resulting in cancellations and delays at several major airports.
More than 200 flights were reported cancelled during the disruption, with Manchester, Edinburgh, Glasgow and Belfast among the airports affected. Although engineers resolved the immediate problem, the effects continued because cancelled flights and displaced aircraft created a knock-on effect throughout the wider aviation network.
For passengers, the timing was particularly frustrating. Many had only recently experienced the consequences of the much larger September 8 outage, when a software defect within NATS’s flight data system caused thousands of flights to be cancelled.
The recurrence has therefore shifted attention from the individual technical problems toward a broader question: whether Britain’s air traffic control infrastructure has sufficient resilience to cope with unexpected failures.
Burnham Demands Answers
Burnham’s response reflects the growing political pressure surrounding the issue.
Rather than simply accepting the explanation for the latest failure, the prime minister has called for a full investigation. The focus is expected to include the immediate cause of the technical problem, the effectiveness of backup systems and whether enough safeguards were in place to prevent a relatively contained failure from producing such widespread disruption.
The government has also stressed that passenger confidence must be restored.
The September 8 incident already prompted Transport Secretary Heidi Alexander to commission an independent review by the Civil Aviation Authority (CAA). That review is intended to examine the causes of the disruption, the resilience of NATS systems and whether improvements or additional investment are required.
The new failure means that the findings of that review are likely to receive even greater attention.
Pressure on Martin Rolfe
Martin Rolfe, the chief executive of NATS, has become a central figure in the controversy.
Airlines including Ryanair have previously called for him to resign following the September 8 outage. The latest incident has revived those demands, with criticism focusing on the repeated disruption rather than on the precise technical cause of any individual failure.
Ryanair has argued that passengers and airlines cannot repeatedly be exposed to large-scale disruption caused by failures in Britain’s air traffic management infrastructure. Other airlines have also expressed concerns about the reliability of NATS systems.
However, NATS has maintained that safety has not been compromised and that the organisation has been taking steps to address technical vulnerabilities.
The distinction between safety and reliability is important. Air traffic control systems are designed with safeguards that can restrict or suspend traffic when technical problems occur. Such measures can help protect aircraft, but they can also lead to severe delays and cancellations when capacity is significantly reduced.
What Caused the Earlier Outage?
The September 8 crisis provides important context for the latest controversy.
NATS published a preliminary report on September 18 explaining that the earlier disruption was caused by a software defect in a specific part of its flight data system. According to NATS, the defect was located in a small subsection of coding within the National Airspace System.
The system is responsible for important information used in managing aircraft movements. The defect emerged during a process involving aircraft identification codes and caused the system to enter a state in which normal processing could no longer continue as intended.
NATS said the problem was unrelated to the major air traffic control failure of August 2023 and rejected suggestions that military activity was responsible. It also said there was no evidence of a cyberattack.
The incident nevertheless had enormous consequences.
More than 2,000 flights were cancelled, while hundreds of thousands of passengers experienced delays or cancellations. Some travellers were stranded for hours, while others were forced to spend the night away from their intended destinations.
Why the Latest Failure Is Different
NATS has indicated that the September 21 problem was not the same technical issue as the September 8 software defect.
The latest disruption was linked to a separate connectivity or equipment problem at the Prestwick centre. The distinction is significant because it means there is not necessarily one single technical fault responsible for both episodes.
Nevertheless, two major incidents in such a short period have raised wider questions about the resilience of the overall system.
The aviation industry is particularly concerned about whether adequate backup arrangements exist when a primary system or facility becomes unavailable.
Air traffic control is a highly interconnected operation. A technical problem in one location can quickly affect flights hundreds of miles away because aircraft movements are coordinated across different sectors of airspace. Once flights are delayed or cancelled, the consequences can continue for many hours after the original fault has been fixed.
Airlines Demand Greater Reliability
Airlines have become increasingly vocal about the situation.
Ryanair has been among the most outspoken critics, calling for stronger action against NATS leadership. Other carriers have also questioned whether enough has been done to prevent repeated failures.
The industry’s concerns extend beyond individual passengers. Airlines face costs when aircraft are stranded, crews exceed their scheduled working hours, flights have to be repositioned and passengers require accommodation or alternative transportation.
Airports also experience significant operational problems when flight schedules suddenly change.
For passengers, the consequences can include missed connections, cancelled holidays, disrupted business trips and additional accommodation or transportation costs.
The financial impact can therefore spread throughout the aviation industry even when the initial technical failure is relatively small.
Government Faces a Difficult Choice
The UK government is a major stakeholder in NATS, holding a 49% share in the organisation. The remaining ownership is divided among airlines, airports, employees and other investors.
That ownership structure gives the government an important role while NATS continues to operate as a public-private organisation.
The government therefore faces pressure to demonstrate that it is taking the issue seriously without prejudging the findings of technical and regulatory investigations.
The independent CAA review will be particularly important. Rather than relying solely on NATS’s internal assessment, the review is intended to provide external scrutiny of what happened and whether the organisation’s systems and contingency arrangements are sufficiently robust.
The government will also have to consider whether additional investment is necessary.
Passenger Rights and Compensation
Another issue raised by the disruption is passenger compensation.
Under existing rules, passengers do not necessarily receive automatic compensation for every delay or cancellation caused by air traffic control failures. Whether compensation is payable can depend on the circumstances and the applicable consumer-protection rules.
The September disruption has nevertheless intensified calls for stronger passenger protections.
The government has previously indicated that proposed legislation would strengthen passenger rights relating to cancellations, delays and assistance.
For travellers affected by repeated disruptions, the issue is not merely financial. Many passengers want greater certainty that airlines and infrastructure operators have effective plans for dealing with technical failures.
The Broader Question of Infrastructure
The controversy surrounding NATS also raises a wider question about Britain’s critical infrastructure.
Modern aviation depends heavily on sophisticated computer systems. These systems must operate continuously and coordinate enormous volumes of information.
At the same time, much of the infrastructure has evolved over many years. Maintaining older systems while introducing new technology creates challenges involving compatibility, testing, cybersecurity and investment.
The September 8 software defect demonstrated how a small problem within a complex system can have consequences far beyond its original location. The September 21 incident has now highlighted the importance of physical and network resilience as well.
For government and regulators, the challenge is therefore not simply to identify individual mistakes. It is to establish whether the entire system has enough redundancy to continue operating when one component fails.
What Happens Next?
The immediate priority will be determining exactly what caused the latest Prestwick failure and why its effects spread so widely.
The CAA’s independent investigation into the earlier September incident will also remain important. Its findings could influence future decisions on NATS investment, system upgrades, regulatory oversight and contingency planning.
For Burnham, the issue presents a test of how the government responds to failures in essential national infrastructure.
The prime minister’s refusal to provide unconditional backing for NATS’s leadership represents a change in tone from the government’s response earlier in the month, when Downing Street said it had confidence in Martin Rolfe to conduct an investigation into the first outage.
At the same time, the government will need to distinguish between accountability for leadership and responsibility for individual technical failures. A full investigation is intended to establish the facts before further decisions are made.
For passengers, airlines and airports, the central demand is straightforward: Britain’s air traffic control system must be reliable enough to withstand technical failures without producing repeated nationwide disruption.
The coming investigations will therefore be closely watched. They will determine not only what went wrong during the latest incidents but also what changes may be required to reduce the risk of another major breakdown.
With two significant disruptions occurring within weeks, the pressure on NATS is unlikely to disappear quickly. The technical explanations may differ, but the political question remains: whether Britain’s air traffic control infrastructure has the resilience needed for a modern aviation system, and what the government should do if the investigations find that it does not.
The crisis over hundreds of cancelled flights today needs is “clearly serious” and “needs to be fully investigated”, Prime Minister Andy Burnham has said.
The cancellation of 200 flights today came is the second problem with UK air traffic control in a fortnight after 2,000 flights were cancelled after air traffic control issues on 8 September.
The chaos has put even more pressure on Martin Rolfe, the chief executive of the National Air Traffic Control Services, who Mr Burnham refused to back.
Asked directly if the head of Nats should be “fired”, the PM refused to answer directly, adding that while further issues “do cause even greater concern… initially this a matter for the Transport secretary” Heidi Alexander.
