New York: Grosset & Dunlap, (1931). Hardcover - Tenth book in this early aviation series for boys, one which embodied the Charles Lindbergh spirit (Rex Lee even resembled Lindbergh) in a boys' adventure series. From the publisher's ad in the back: "The author of this series of exciting flying stories is an experienced aviator. He says, "During my five years in the army I performed nearly every sort of flying duty -- instructor, test pilot, etc., in every variety of ship, from tiny scout planes to the gigantic three-motored Italian Caproni." Not only has this author had many experiences as a flyer; a list of his activities while knocking around the country includes postal clerk, hobo, actor, writer, mutton chop salesman, preacher, roughneck in the oil fields, scenario writer in Hollywood and synthetic clown with the Sells Floto Circus. Having lived an active, daring life, and possessing a gift for good story telling, he is well qualified to write these adventures of a red-blooded dare devil young American who became one of the country's greatest flyers." Glossy frontispiece. Lists to #8 in the ads in the rear. 215 pp plus 3 pp publisher's ads.
