Shootdown

On board a Jumbo jet approaching Heathrow airport there is an explosion and the giant aircraft plunges to earth in the London suburbs. Even as crash investigators begin their painstaking task amid the carnage a message is received claiming that the aircraft was shot down by terrorists and threatening further shootdowns if world political leaders fail to take immediate action to meet their demands. Mark Holtby Middle East based correspondent for the International Press Agency is one of the few survivors from the crash. Despite harbouring doubts about the authenticity of the terrorist message Mark sets out to try and track down its authors.
