Gene Kranz’s personally-owned and -used Gemini Operations Handbook for the Gemini 9 flight, 9 x 11.5, dated April 22, 1966, consisting of several hundred pages of mission materials providing extremely thorough procedures, descriptions, and several detailed pull-out schematics and diagrams. A handful of pages have brief handwritten notations or corrections, and four pull-out schematics are extensively annotated by Kranz. These annotated schematics include one for the Agena-Gemini Interface and three related to systems used during the EVA, including environmental control, propulsion, and power. In fine condition, with the front cover and one schematic detached from inside the binder. Accompanied by a letter of authenticity from Kranz, in part: “The Gemini IX Flight Book with mission materials that accompany this letter come from my personal space archives. Contained within is a compilation of information for my personal use as Flight Director. The material included, reflected what I determined most useful to have at my fingertips…This material was used at my console throughout Gemini IX as a primary resource for coordinating that mission. For my ease of use, this binder has been organized and tabbed, was carried everywhere and kept on top of my console during the actual mission.” An extraordinary piece offering remarkable detail on the inner workings of the Gemini spacecraft and space program as a whole.
