This is a combination history/how-to of rocketry. From the beginnings to the future of this explosive subject, the author has been consistently aware of the excitement it generates. This is reflected in a vocabulary that (while simple enough to remain in the grasp of this age group) is filled with triggering, active, colorful verbs. The illustrations, particularly where they are cross-sectioned diagrams, support the text and help explain the difficult phases of huge rocket construction programs.
