Travelers in the UK are facing severe disruptions following a significant air traffic control glitch that has led to the cancellation of over 2,000 flights and widespread delays at major airports. The technical issue, identified by the National Air Traffic Services (NATS), impacted flights not only within the UK but also affected air travel worldwide, with thousands of passengers stranded and forced to sleep on floors at airports. Despite a swift response from airlines and air traffic authorities, the chaos is set to continue as the backlog of flights is being addressed. The air traffic control chief is under scrutiny, with an investigation into the outage expected to be delivered within a week. Officials have ruled out a cyberattack as the cause of the disruption. Passengers are urged to check for updates as the situation evolves, with many still facing uncertainty about their travel plans.
