> we deleted the records on how we came up with it. we have the blue prints but we don't have the notes of the many many adjustments that were made during its construction. some of them were found in old filing cabinets at the companies that manufacture the parts but most are lost to time because they were thrown out; also this whole "it was the greatest achievement of mankind so why was any of the documentation lost" is just post hoc storytelling and not how things were done back then.
