Air India flight diverted to Zurich as UK air traffic control system fails

On a Tuesday in September, a technical failure at NATS — the nervous system of Britain's skies — brought one of the world's most complex aviation networks to an abrupt and humbling standstill. More than 290 passengers aboard Air India flight AI 131, mid-journey from Mumbai to London, were rerouted to Zurich, their destination suddenly unreachable. Across four of Britain's busiest airports, over 600 flights were cancelled, reminding the modern world that the invisible architecture holding its movement together is never as permanent as it seems.
