At one time we could DO things like that
On a similar note, IIRC the Saturn rockets used for the Apollo missions could not be made today - the plans are lost. OTOH, a local company is working on fusion propulsion.
I recently read an article on what website I can’t recall,but the article said that there is a Company who is going to reverse engineer the engines from the Saturn 5 and manufacture them.
What they dis is they went to a number of museums that had the engines and disassembled them,then scanned the parts into a computer system.
The main engines for the Saturn 5 are supposed to be the most powerful rocket engines ever built.
See post #39. Pretty cool stuff. Those guys on the left look like kids!
