**Air Traffic Control Outage: Transport Secretary Calls for Investigation**
In a recent statement, Transport Secretary Heidi Alexander revealed that the technical failure of the UK's air traffic control system, which led to significant flight disruptions, was avoidable. The outage, which occurred on Tuesday, lasted for approximately four hours and resulted in the cancellation of over 2,000 flights, affecting thousands of passengers traveling to and from the UK.
During a session in the House of Commons, Alexander announced that she has initiated an independent investigation by the aviation watchdog into the incident, which is managed by NATS (National Air Traffic Services). The Transport Secretary met with NATS CEO Martin Rolfe to discuss the incident and the response measures taken to mitigate the disruption. She emphasized the need for accountability and expressed her belief that the situation could have been prevented.
"NATS has apologized for this being their third major technical fault in three years," Alexander stated. She also noted that a cyberattack could be ruled out as the cause of the failure. However, she underscored the necessity of asking "tough questions about the resilience of NATS systems" and the implications for consumer rights in the event of such outages.
The government has expressed confidence in Rolfe, who has been at the helm of NATS for 11 years, despite calls from airlines such as Wizz Air and Ryanair for his resignation. In response to the incident, NATS has been tasked with conducting its own investigation and is expected to report back within a week. Additionally, Alexander has requested a broader independent review from the Civil Aviation Authority, which is set to provide an update in six months.
Airlines UK, the trade association representing the UK’s airlines, has voiced serious concerns regarding the recurring technical failures at NATS. Tim Alderslade, the chief executive of Airlines UK, highlighted that the ongoing issues have caused major disruptions across the aviation network and emphasized the need for accountability. "The result is a system where airlines pick up the bill for the mistakes of others, while the organizations responsible face little or no financial consequence," he remarked. Alderslade pointed to the Civil Aviation Bill as a potential avenue for addressing these concerns.
The recent outage is not an isolated incident; NATS has faced similar challenges in the past. Earlier in 2023, a computer shutdown during the August bank holiday weekend led to chaos for approximately 700,000 passengers. In that instance, it took an engineer three hours to reach the site and rectify the fault. A smaller outage in 2025 also resulted in 150 flight cancellations.
The technical issue on Tuesday was first confirmed by NATS at 13:46 BST, which stated that it was investigating a "technical issue" causing disruptions to flight departures. The problem was traced to the flight processing system at NATS' Swanwick Centre in Hampshire, one of its two air traffic control centers, with the other located in Prestwick, Ayrshire. This system is crucial for processing flight plans and operational information, enabling air traffic controllers to manage the flow of air traffic safely and efficiently.
By 19:30 BST on the same day, NATS announced that the system issue had been resolved and that efforts were underway to clear the backlog of flights. Despite these efforts, the number of cancellations and delays continued to rise, with over 2,000 flights affected by Wednesday evening, according to data from flight analytics firm Cirium.
As the investigation unfolds, the focus remains on ensuring that such disruptions do not occur in the future and that accountability is established for the organizations responsible for air traffic management in the UK. The outcome of the independent reviews and the steps taken by NATS will be closely monitored by both the government and the aviation industry.
