UK aviation disruption via NATS technical failure
Overview
A technical failure in the flight data processing system of National Air Traffic Services (NATS) caused widespread disruption to air travel across the United Kingdom and parts of Europe. The outage, which began on Tuesday, September 8, 2026, resulted in more than 2,000 flight cancellations and affected approximately 330,000 passengers. A preliminary report identified the cause as a “millisecond-long software defect” within the National Airspace System (NAS). NATS CEO Martin Rolfe confirmed that aviation safety was not compromised and that the incident was not a cyberattack.
On September 21, 2026, a secondary technical issue emerged at the NATS Prestwick centre in Scotland. Described as a connectivity issue within a portion of its system network, this incident primarily affected airspace in Scotland, Northern Ireland, and northern England, causing delays and cancellations at airports including Glasgow, Edinburgh, Manchester, Belfast International, and Stansted. Aviation analytics firm Cirium reported that approximately 150 to 200 flights were cancelled due to this specific disruption. NATS stated that this fault is unrelated to the software defect experienced earlier in the month.
The cumulative impact of these failures led Ryanair to report more than 1,000 flight cancellations throughout September, citing the two major NATS outages alongside external factors like strikes in Belgium and volcanic ash from Mount Etna. In response to the repeated service failures, Ryanair’s chief operating officer, Neal McMahon, has called for the resignation of NATS chief executive Martin Rolfe. Additionally, UK Transport Secretary Heidi Alexander has summoned NATS chairman Sir Warren East for urgent discussions regarding infrastructure issues, following her order for an independent investigation by the Civil Aviation Authority (CAA).
