Story summary

The UK's National Air Traffic Services (NATS) caused over 2,000 flight cancellations and widespread disruption across British airports on September 8, 2026, due to a millisecond software defect. The glitch affected hundreds of thousands of passengers and led to an estimated loss of millions for airlines as they refunded customers and rescheduled flights. This incident follows two previous major outages in the UK since summer 2023, increasing pressure on NATS CEO Martin Rolfe who faces calls to resign. Airlines like Ryanair are demanding action from regulators, while transport minister Heidi Alexander ordered an independent review by the Civil Aviation Authority (CAA) to investigate the issue further.
