This collection contains the papers of Otis Jerome Parker, an aerospace engineer employed at the National Aeronautics and Space Administration (NASA)'s Langley Research Center during the Gemini, Apollo and Skylab projects. The collection consists largely of a few NASA publications regarding the design and development of "jet shoes" and other devices intended to provide propulsion and maneuverability during extravehicular activity (EVA) in spaceflight. The collection also includes Langley inter-office communications regarding Parker and the projects on which he worked, as well as a small set of photographs of Parker and EVA propulsion devices. With the exception of one photograph, this collection consists of photocopied materials.
