Meh. I&#x27;d like to see the complete engineering documents for some of the older missions.<p>That means hundreds or thousands of sheets of drawings, and thousands of pages of specifications.<p>In case you haven&#x27;t worked on a large engineering project, every part gets a detail drawing; if it&#x27;s off the shelf, it usually  gets a source control drawing; every assembly gets an assembly drawing.<p>There might also be wiring diagrams, harness drawings, airline diagrams, and system block diagrams.<p>It can&#x27;t all be classified, can it?
