In this hardbound edition of the second book in the series, a consortium of airlines industry executives beg Tom Swift and his father to help them out of a spiraling problem. No matter what they try to do to keep airport and aircraft noise down, and no matter how far out of town airports are constructed, people snap up the land around, build housing complexes and the folks who move in begin complaining about the noise. On top of this, fuel prices are out of control. Can Tom do something? Can he find a way to reduce aircraft noise levels far below anything anyone else has been able to accomplish. Is it possible for him to find a way to make jet turbines super fuel efficient? And, can he do this all for not just new jets but for the huge fleets of existing aircraft out there? With so many things to tackle, about the last thing he needs is an industrial spy out to steal both his plans and the publicity, and an unprovoked missile attack as he does a test flight. If he has to give up, what will happen?
