"Read this book. You’ll find plenty about John and all the other sky-high crackpots who were in the field with him and you may even get (as I did) a glimpse of the heroic excitement that seemed to make it reasonable to cuddle with death every waking moment—to say nothing of learning a heck of a lot about the way in which the business of science is really conducted."
— Issac Asimov, from the foreword
"Ignition!, originally written in 1972, is back in print after a long hiatus. A classic book, it tells a rollicking story of an era when space was the frontier. An informative history, it reads like an adventure story."

"This insider's account of the early years of rocketry captures the excitement of researching and developing technologies that lie outside the realm of computer science."

"Ignition! is a hard-to-get-your-hands-on account of early rocket science...Clark was an American chemist active in the development of rocket fuels back in the 1960s and 1970s, and the book is both an account of the growth of the field and an explainer of how the science works."

"The funniest, most accessible book on rocket science. . . . Often hilarious, always informative, this history of rocket science is a must-read. It's rare that a book about as high-minded and serious a topic as rocket science manages to be both highly informative and laugh-out-loud funny. But if there's a better way to describe John Clark's Ignition!, I've yet to discover it. A cult classic among chemists."
