Flight time from London to Sydney- ninety minutes. Sabre 005, a synergetic, air-breathing rocket engine, that will revolutionise air travel as the world knows it. Paul Santos, a French engineer, developed the aircraft. A jet in the atmosphere and a rocket in space, Sabre 005 is set for its first ever commercial test flight - and its fare-paying passengers are already scheduled for one year's time. Joe Yavanoski, a union boss forced to retire, knows the threat Sabre 005 poses. Its success will spell the death of his country's former great aircraft industry and the loss of hundred of thousand of jobs, including that of top engineer Jean Lesseps. Together, Yavanoski and Lesseps hatch a plan to shatter the public's confidence forever - the perfect undetectable bomb that will wipe out Sabre 005, its passengers and its crew, once and for all. All they have to do is get on board . . .
