X-15: Extending the Frontiers of Flight

Professionally converted for accurate flowing-text e-book format reproduction, this is an excellent history of the famous X-15 rocket plane, called by Neil Armstrong "the most successful research airplane in history." This is a truly authoritative work covering all aspects of the historic program.
Because of the unusual size of this document, it is presented in two parts.
