NASA asked several former SR-71A staffers to help secret restart

    A couple of questions/observations:

    1) when people say "destroyed the jigs, tools and spares in 2007" What do they actually mean? Burying things isn't destroying. Putting them in a furnace is destroying. Is it possible that both parts, and tools actually are recoverable e.g. from the seabed? The dimensional stability might be off, but to help reconstruct tools, it's not nothing. Likewise digging up something buried in its packing crate is not rocket science.

    2) "that would be ludicrously expensive" doesn't mean much any more. It's not unlike "we can't make a saturn 1 any more because the tools were destroyed and it would be ludicrously expensive to make an F1 engine" -well yes, but thats not impossible, it's just unlikely and expensive. So maybe this is unlikely, expensive but ... has a unicorn sugar daddy?

    3) there are craft in all sorts of places. Not just on sticks outside NASA property. I am not a historian or a federal government employee, but I wouldn't think it impossible for people to ask other agencies to let you inside the shell and remove the bits you want, or even ask for it back. The one on a stick in Balboa Park San Diego might have associated boxes of bits-and-bobs..

    4) its a titanium alloy. It's temperature and corrosion resistant, noting some things (like chlorine according to the web) are bad for it. It's not made of pure chinesium or balsa wood. Interior surfaces would be in pretty good shape.

      The bigger problem there is that we don't have the people any more.

      The Rocketdyne F1 was the pinnacle of hand-crafted engineering, with each engine being slightly different and the people having to account for those differences during assembly. It has a whole bunch of complicated welds which require a lot of tweaking, adjusting, and literally days of welding work? Neil's got to go to the moon, so you better get to it!

      Those highly-skilled highly-specialized engineers don't exist any more, and for a good reason: with CNC and robots we can achieve far superior results for a fraction of the cost. It just requires the designers to make it automation-friendly from the start. Those skilled people retired (and by now died) without a replacement, because the job had become obsolete.

      So no, we literally cannot build a new Rocketdyne F1. We can design and build a better F1-like engine, though!

        You don't have the education system and work ethic, stable family, curiosity. Many young people feel college is a waste and YouTube or AI has all the answers. Children in schools even now in 2026 right up to high school and even college can't read. Many who can read can't comprehend what they are reading.

        In addition to that I recall a UK study that said smartphones have caused a lack of hand dexterity. Not social media or content but the phone itself a two dimensional surface means hand dexterity is not developed. People do not have hobbies like wood working, sewing, anything that involves fine manipulation and strength. The biggest hit is to the medical field and lack of surgeons because people in medical school now do not have fine motor skills needed for the job.

          I’d suggest questioning the sources you are reading. Wood working and sewing are hugely popular hobbies across younger generations. There used to be a site, Ravelery.com maybe, that was on here all the time because of their engineering blog and all the work involved in sharing sewing patterns.
