UK air traffic control outage caused by software defect, says operator
The glitch triggered backup protocols and manual flight handovers, with airlines saying the disruption cost them millions of pounds.
- On Friday, the National Air Traffic Services revealed a software defect in its flight data system caused the September 8 outage, grounding more than 2,000 flights and affecting 300,000 passengers across UK airports.
- The flaw occurred when a manual request for an aircraft identification code was paused for a higher-priority task, causing corrupted data 'in the space of a millisecond,' Nats said.
- Stranded passenger Addie Kitson, 26, faced almost £100 in unexpected costs after her flight was diverted to Stockholm, spending 19 hours at the airport.
- Transport Secretary Heidi Alexander described the disruption as 'completely unacceptable,' ordering the Civil Aviation Authority to launch an independent review due within six months.
- Nats CEO Martin Rolfe apologized to affected passengers, stating "it's our job to get people where they want to go, quickly and without delay," as a permanent software fix is safety tested and deployed.
