In the field of private executive aeroplanes, number one is the Silver Streak - a twin engine jet, designed to seat twelve in the utmost luxury. Capable of flying three thousand miles without refuelling, fully automatic - a jewel. With its computer, the size of a small camera, except for take off and landing, you could rely on automatic pilot. The Barracuda, as this plane is named, is a corporate plane, but nobody ever uses it, except J Bruce Proctor. He is the only passenger, with the exception of his secretary.
