On the 18th, the UK's National Air Traffic Management Services released a preliminary investigation report. The report clarified that the extensive disruption experienced at multiple airports across the UK last week, which led to the cancellation of over 2,000 flights, stemmed from a software malfunction that occurred within a mere millisecond. This issue, rather than human error, was the root cause. The paralysis impacted several major airports, throwing the travel plans of hundreds of thousands of passengers into disarray. It was not until several days later that airport operations gradually began to return to normal.
