UK airports grounded by air traffic control technical fault

On a Tuesday afternoon in September, a technical failure within Britain's National Air Traffic Services brought the departing skies to a halt, grounding flights across ten major UK airports and sending ripples of disruption as far as Paris and Alicante. The fault, affecting only outbound flights, left thousands of passengers stranded in terminals and on tarmacs — caught between systems they depend upon and systems that had, without warning, failed them. It is a familiar modern parable: the invisible infrastructure that quietly governs movement, suddenly and acutely visible in its absence.
