Super early spiral-bound report prepared by Lockheed's Space Systems Division entitled "Space Shuttle: Final Report, Integral Launch and Reentry Vehicle, Executive Summary" (LMSC-A959837), 8.5 x 11, 20 pages, December 22, 1969. The report provides a summarized overview of Lockheed's studies in "reusable launch and space operations concepts," which focused on a fully reusable two-stage lifting body shuttle. In these efforts, "computer programs closely coupled with analytical design were employed to reach a multiplicity of design solutions to the central problem of orbiter and booster sizing." The report provides several interesting charts and diagrams associated with the Space Shuttle Orbiter concept, covering materials and design, engine performance, probability of crew survival, cost estimates, scheduling, and other project essentials. In fine condition.
