The Space Congress Proceedings collection has been created in collaboration between Embry-Riddle Aeronautical University and the Canaveral Council of Technical Societies (CCTS). Unfortunately, the 1975, 12th proceedings were not available for digitization or publication in Scholarly Commons. If your institution has access to this publication in print or digital format and would like it to be published with this collection, please contact the Scholarly Commons Administration at dbcommon@erau.edu .
