A readable and highly creditable account of the boyhood and early manhood of the pioneers in American aviation, by the master journalist. Through episodes and conversations which are plausible enough, the author follows the enterprising brothers from their first adventures in construction, when- aided by their mother, they made a sled with a minimum of ""wind resistance"", through experiments with kites, printing presses, bicycles and a glider, to the famous take-off at Kitty Hawk in 1903 with an engine-glider. However, the author has created also two likeable young men, eager, inquiring, persistent both in business and scientific projects. With characteristic thoroughness and a solid basis of practical experience, the brothers hypothesized, experimented, chose and rejected so as to realize their dream of flying. A lively boost for aspiring scientists, inventors and aviators.
