National Air Traffic Services cites software glitch for travel chaos

by@BBCNews

Summary

The UK's National Air Traffic Services (Nats) reported that a software defect caused a significant air traffic control system failure earlier this month, leading to more than 2,000 flight cancellations and disruption for hundreds of thousands of passengers. Many were left to sleep on airport floors or remained stranded overseas as flights into and out of major airports, including Heathrow and Gatwick, were severely impacted. The government has ruled out the possibility of a cyber attack and received assurances from the Ministry of Defence that no military aircraft errors contributed to the incident. An investigation by Nats into this technical fault is underway, alongside an independent review mandated by UK transport authorities, amid ongoing scrutiny of the provider's flight processing system reliability given previous technical issues.
