The UK’s worst air-traffic outage in a decade was caused by an anomaly in the airspace manager’s software system, which confused two geographical checkpoints separated by some 4,000 nautical miles.
The UK’s Civil Aviation Authority said Wednesday it will conduct an independent review of the incident, which forced hundreds of flights to be canceled or delayed last week after an error in processing an airline’s flight plan.
