Tailspin
(Book)

Rye Mallett, a fearless "freight dog" pilot charged with flying cargo to far-flung locations, is often rough-spoken and all business, but soft on regulations when they get in the way of meeting a deadline. But he does have a rock-solid reputation: he will fly in the foulest weather, day or night, and deliver the goods safely to their destination. So when Rye is asked to fly into a completely fogbound northern Georgia town and deliver a mysterious black box to a Dr. Lambert, he doesn't ask questions. As Rye's plane nears the isolated landing strip, more trouble than inclement weather awaits him. He is greeted first by a sabotage attempt on his plane that causes him to crash land, and then by Dr. Brynn O'Neal, who claims she was sent for the box in Dr. Lambert's stead.
