There were reasons behind Dana Trump's angry roaring. Although he did not have a good understanding of industrial processes, he did have some basic technical knowledge. High-precision industrial equipment could not simply be produced just because one improved the standard of the design. It was impossible to manufacture certain advanced equipment even with a full set of design blueprints. It was because the material technology could not meet the minimum standard needed. It was because the accuracy of industrial processing was not accurate enough, therefore, quality components could not be produced. It was the same reason why the earliest humans could not create a machine gun. It was useless even if one gave them the full set of design blueprints for the atomic bomb.
