UK airspace chaos explained: How a 'huge network failure' has sparked delays for thousands travellers - so could a CYBERATTACK be to blame?

Britain's air traffic control systems have been hit by a'huge network failure' today -- prompting confusion, chaos and huge delays for thousands of holidaymakers. NATS, the national air traffic controllers, stressed that UK airspace is not closed but it has brought in traffic restrictions to'maintain safety'. Engineers are working hard to fix the fault but hundreds of flights in and out of the country have been delayed – some for'at least 12 hours' – and there are fears the knock-on effect could last days. No cause of the technical issue has been revealed but social media is rife with claims that a cyber attack might be to blame. It comes just months after all flights across America were grounded for the first time since 9/11, when an unexplained computer system failure prompted fears that hackers had targeted the network.
