A software defect in the UK's air traffic control system led to a six-hour outage, causing widespread flight cancellations and delays. The incident, which affected hundreds of thousands of passengers, was attributed to a corrupted flight data output that occurred in a millisecond during code processing.
Ministers have expressed concerns over the lack of clarity in the report regarding why the issue was not identified sooner. The Civil Aviation Authority will conduct an independent review to assess the findings and future resilience of the air traffic system.
