Official NASA manual entitled “Skylab Program, Introduction, by Glen H. Cress,” 76 pages, 10.5 x 8, dated April 1970, prepared by the Mission Simulation Branch, Flight Control Division at the Manned Spacecraft Center. The manual is divided into five topics—Skylab Program Objectives, Skylab Program Schedule, Mission Profile, Orbital Assembly Configuration, and Orbital Assembly Systems—with the foreword explaining: “The material in this study manual was taken directly from a video tape made for TV classroom presentation. The text is an exact transcription of the speaker’s words, which were meant to be heard, not read. Although it may read rather strangely, the text is technically correct and the sequence of words and pictures is the same as the TV presentation.” The manual is stapled in the upper left corner, and the front cover bears an ownership notation. In fine condition. From the personal collection of Paul Kruppenbacher, a member of the NASA Houston Landing and Recovery Division who trained Apollo astronauts in water recovery procedures and was deployed on U.S. Navy aircraft carriers for crew and spacecraft recovery operations.
