Second UK air-traffic outage in weeks sparks calls for resilience overhaul
A second UK air-traffic control outage in weeks disrupted hundreds of thousands of travelers, with roughly 2,000 flight cancellations over two days at the Swanwick centre and about 150 cancellations at Prestwick, prompting airline criticism and renewed calls for greater system resilience while a government-ordered independent review is underway; NATS defends the complexity of the system and says outages can occur.
