FOREWORD:

• I know in advance of publication that this book will be subjected to strong criticism by some people and will be hailed by others with a good chance of being labeled “controversial.” Rocket experimentation by amateurs just happens to be one of the areas where people fail to see eye to eye.
• Nor is this controversy of whether people should be permitted to do as they please (within reason, of course) or whether Something Should Be Done as new as it looks. Even before the space age was headlined by the beeps from Sputnik No. 1 there were dedicated groups of amateur rocket experimenters who could not only point to successful flights but to an unblemished safety record.
• They could also tell stories of harassment of various kinds. But it is true that the problem has assumed major pro- portions since Sputnik No. 1. For a year or so virtually every youngster wanted to build rockets. And there have been accidents, even fatal ones.
• The reaction to these accidents took different forms. On the one hand several com- panies which are in the rocket business issued safety manuals free of charge. So did the Army. Somewhat later the Armed Forces began to assist amateurs actively, as is told in the body of the book by the man who did much of the assisting. On the other hand the large and respected American Rocket Society came out repeatedly against any and all amateur experimentation.
• The two arguments most often advanced are (A) it is not safe and (B) the amateurs will not be able to discover something that the professionals have not already done. As for argument (A), the simple fact of life is that it can be highly unsafe but that accidents are always due either to carelessness or simple lack of knowledge. Both of these can be remedied. As regards argument (B), my favorite story is that at one university I saw a medical student dis- sect a human hand. I could have told him that he would not learn anything that could not be found in medical texts, with fine colored illustrations, and that he had absolutely no chance of making a discovery. My statements would have been perfectly correct, yet have missed the mark by several miles.
• That student did not lift out the various blood vessels and muscles to find something new for others, he did it for himself, in order to learn and to gain practice. I might also ask where the professionals came from originally. The young Russian student of engineering, Blagonravov, certainly was not a professional back in 1932 when he built his first rocket.
• And then there was a group of people on the outskirts of Berlin building rockets. Their names were, in approximate order of age: a high-school teacher called Strachea man with a degree in engineering but no engineering practice (because of the first World War and the subsequent inflation) called Nebel a man who had studied mainly zoology and
• who had thought he would become a geologist, myself; a young man who had begun to study engineering (interrupted by the inflation, too) and who happened to be the only one with machine- shop experience, Klaus Riedel; a high-school graduate who was beginning to study engineering, Wernher von Braun; and finally, a high-school boy who intended to study engineering later on, Helmuth Zoike. This group of rank amateurs built the first German liquid fuel rockets.
