With cool scientific detachment, Zachringer has assembled a composite picture of the history of Russian accomplishments in all phases of space technology, dating from before the Russian Revolution. As calm as the presentation is, the effect is harrowing, because Zachringer is convinced America needs to be shocked and awakened from her confused daydream that no nation can be better than we in a technical field. He advocates a complete revision of our defense system, in order to free our vast technological potential from bureaucratic restrictions and to insure getting the most and best research and defense for the dollars we must inevitably spend. The author is himself a scientist, and head of the American Rocket Company. For many years he has kept in intimate touch with whatever reports have been available on Russian developments. Fundamentally, Soviet Space Technology is exceedingly technical, and requires more than casual reading. But even the average layman will find that the style is intelligible and the book is replete with plain-speech paragraphs worth searching out because they deal precisely with data that have long languished behind a clinging of imprecision. The tables disclose much of statistical interest, the glossary is excellent from the layman's point of view and is complemented by an alphabetical roster of Russians who have made important contributions to the Soviet race for space.
