Air travellers on Wednesday witnessed chaos at London airport after a major technical failure forced air traffic controllers to shut down British airspace for over an hour, grounding flights at the height of the peak summer travel season.
The disruption, triggered by a 'radar failure' at NATS Swanwick air traffic control centre, paralysed operations at major airports including Heathrow, Gatwick, Birmingham, and Manchester, as well as regional hubs from Newcastle to Aberdeen.
