Overview
- A technical fault in NATS’ flight-processing system detected on Tuesday caused widespread cancellations and delays that left thousands of passengers stranded and created a multi-day backlog.
- Engineers implemented a fix late on Tuesday and NATS says normal operations have resumed, but airports and airlines are still clearing the large tail of delayed and cancelled services.
- NATS chief executive Martin Rolfe apologised, ruled out a cyberattack, and has been asked by Transport Secretary Heidi Alexander to produce a full report within one week.
- Major carriers publicly criticised NATS, called for accountability and argued the organisation’s pay, dividend decisions and investment choices have weakened operational resilience.
- The episode has renewed scrutiny of NATS’ governance and ageing technology—reporting cites a decades-old core processor and legacy code in Southampton—and raises questions about whether the current public-private funding model prioritises upkeep.
