Along those same lines, the designs for the Saturn rocket were supposedly scrapped (some
say for political reasons). A few years ago someone did a detailed 3D scan of the F1
engine (first stage engine) and used that to develop a compatible but more modern
successor (called F2 I think).

Yup, A guy I know was in the aerospace fabrication business (now retired). A few years
back, he showed us some horribly degraded mylar plots of some military aircraft drawings
that were all the manufacturer could come up with. The Air Force was doing a major
rebuild of those airframes, and needed some skins shaped to replace the tailplane
airfoils. He knew where possibly the only airfoil bender was, and quickly bought it from
a scrap dealer. They then had to scrutinize the plots and try to extract the original
dimensions so they could bend the skin to the required shape. Lucky the original
manufacturer at least had some form of document still available, or they would have had to
do some 3D scanning of an existing part that was not too far gone. You would probably be wrong, it likely was
archived before
it stopped being used. But that won't do you any good as
even if you could submit a FOIA request for it the cost of
recovering it would be prohibitive and they would not have
to honor it. :-)
I don't think so--the project I had in mind was a military
project that
sunset some time in the late 1970s.
