I know EXACTLY what you mean. It's no different on the machined parts. The paper work was insane. A detailed inspection report with every single dimension and the measurement on it. Metallurgical analysis report, heat treat time/temperature plots, NDT certs, every anodize, paint, assembly, sealant, etc., etc. Certifications for everything! Every single part literally had a book that went with it. When you put it all together for the whole assembly the paperwork really did weigh more than the assemblies. But we didn't have to have clearances, we didn't have more than machined part blueprints and processing specs. They ended up at ATK that was formerly named Morton-Thiokol.
Sound exactly like what we have to do, every serial number of every screw documented then verified and re-verified by a officer. I know where alot of our government money is goin to though, they spend $900 dollars on a washer when I can go to Lowes and get the same one for .05 cents lol.
