"As the Apollo moon program wound down in the early 1970s, NASA's attention turned toward the next phase in its manned space agenda: the development of a reusable 'space truck' that could ferry men and material into low orbit quickly and cheaply.
Various designs and configurations were proposed and evaluated. All had their strengths and weaknesses. In 1972, North American Rockwell -- one of America's top aerospace contractors -- asked engineer Harry Scott to develop a design that would minimize the propose craft's length without sacrificing cargo space. His solution was to turn the cargo bay sideways, resulting in this unique 'flying breadbox' concept.
Although theoretically practical, North American Rockwell's Shuttle Concept C-0157 never developed beyond the proposal stage."
"Released in early January 2007, this solid-cast resin kit was patterned by Scott Lowther, cast by Controlled Energy Designs and featured custom decals by JBOT."
