When a fire disrupts the London Air Traffic Control Centre, the controllers move to an emergency control room at Heathrow - which is exactly where a group of terrorists want them. The crisis deepens and the whole of London's Air Traffic Control system comes under attack. Despite facing personal danger, the controllers struggle to keep the airspace safe. Desperate measures are needed to discover who is behind the attack, and what they want. Measures that put innocent lives at risk. As the answers begin to emerge, it becomes clear that far more is at stake than the safety of aircraft and passengers. By then, there seems no way to stop a terrorist attack far more shocking than anyone had imagined. David Hough takes his reader on a nail-biting journey: the clock is ticking and the stakes are getting higher and higher - and the disaster is getting closer an closer. A rip-roaring, page-turner of a novel.
