all of the documentation of the tests and results are gone. scrapped. Junk heap of history.
Men risked their lives to plant a flag and were stabbed in the back. Moonwalkers feel betrayed that in for 40 years manned flight exploration was killed off.
There is a site that refers to it as “the second assassination of JFK”.
Not saying we are going to “rebuild it” but plenty of lessons were learned from successes and failures.
The point is even if we wanted to WE CANNOT REBUILD IT. We lost the technology designs.
What are "technology designs"? The Saturn V was designed using drafting tables and slide rules. Those "designs" would be worthless anyway in an age when all of that stuff is done by CAD/CAM.
We don't have the Saturn V production tooling anymore; it would have to be rebuilt. That's part of what you typically lose when you shut down a production line.
There are at least two (three?) production Saturn V's in museums. One is in Huntsville and the other is at the Cape. (There may be a third; I'm not sure.) There are also spare parts in storage. They can be reverse-engineered, but why?
There's an article on Ars Technica about a group which reverse-engineered an F-1 engine pulled from storage in order to design a modernized version for the SLS booster. I would suggest you read it.
