"X-15: Extending the Frontiers of Flight is the result of 15 years of research into the cooperative NASA-Air Force-Navy X-15 research airplane program. This history covers the program form its inception, through t he preliminary conceptual studies, the airframe and engine competitions, the flight program, and the follow-on research program. Particular attention is paid to the program highlights, such as the development of a workable full pressure suit and early biomedical testing in the human centrifuge at the Naval Air development center Jonesville." - NASA
