British transport minister Mark Harper said that it would take days to resolve the disruption to flights into and out of the country after air traffic control systems were hit by a technical problem. Over 1,500 flights were cancelled - one of the country's busiest travel days. Air traffic controllers were forced to switch to manual systems.
Mark Harper said that government officials did not believe the technical problem was the result of a cyber attack. "There is going to be some knock on impact today and I suspect for another few days as airlines get their planes and get their services back to normal," he told the BBC. Aviation analytics firm Cirium said 790 flights departing UK airports were cancelled and 785 flights due to arrive were cancelled on Monday. This means that just over a quarter of all flights into or out of the country were affected, Reuters reported while travelers scampered amid the disruption sharing their experiences on social media.
