The eagle of the title is the sobriquet for Harry Blunt, a former serial fire spotter in the Forestry service, and hero of the Alaskan bush pilots. The lives Blunt saved, by landing in the midst of fires to rescue trapped campers, or by giving due warning of conflagration called for skill and courage enough. His contribution to making commercial air routes practicable and profitable are likewise immeasureable. But the narrative builds up to and stands for all its worth on yet another phase of his achievement -- a scientific expedition he brought about. Father Hubbard, world famous volcanologist, was flown by Blunt directly into the fury of Aniakchak. The climax of this agonizing feat was a downdraft of cold air which- while Father Hubbard filmed the spectacle, came perilously close to writing finis to the venture by sucking the plane into the crater. True flying adventure- for the addicts.
