Yes. Britain’s air traffic control provider NATS suffered an hours-long systems failure on Tuesday, September 8, 2026, that halted flights and stranded hundreds of thousands of passengers. Aviation analytics firm Cirium said about 2,000 flights to and from UK airports were affected across Tuesday and Wednesday, with roughly 30% of scheduled departures grounded on Tuesday.
Transport minister Heidi Alexander told parliament she did not believe the outage was a cyberattack, and the government gave NATS CEO Martin Rolfe one week to report back while ordering a separate Civil Aviation Authority review. It was the second major NATS failure in three years; flights resumed Wednesday with lingering disruption as aircraft and crews were out of place.
