Informative, intermittently interesting account of air postal service in the United States, with a preceding bow to the pigeon post, a final puff for missile mail. Mr. Glines describes the early exhibition flights, the first touch-and-go official flight (and the related stamp bonanza), the multiplication and extension of routes under Post Office Department auspices, the achievement of transcontinental service by all-night flying; excerpts from first-hand accounts demonstrate the hazards of flying by road maps and landmarks.
