Orville and Wilbur Wright diligently photographed each phase of their experiments in order to learn from their mistakes as well as keep a pictorial record of their progress. Because of their almost obsessive attention to detail, an amazing record of their accomplishments still exists. Freedman's incorporation of some of this archival material brings a dynamic visual dimension to previous accounts about the two brothers' efforts to create a machine which could be flown. The author's skillful uses of unfamiliar details about the lives of two siblings who worked, lived and even "thought together" makes compelling reading. His lucid explanation of the physics of flight rounds out this interpretation of the important technological milestone achieved by two very human beings. (Ages 9-14)
