@musul Imagine you're a guy working for Elon Musk in SpaceX. Your project just got canned and you're in a bad mood.
Some guy who you went to school with walks up to you and says "hey my engineering firm that I work at just developed a fully functional viable spacecraft that can bring passengers into orbit at a low low cost and is fully reusable, can you help me out?"
It's utterly preposterous that someone would have actually done that. There would be patents filed, papers written, people hired, and it'd not be a secret.
And no-one who actually did that with so much secrecy would ever say "hey I just did an amazing thing while keeping it under wraps, want to see it?"
It's not something believable at all. Sounds more like the MC would want to get into her pants by offering her something amazing and miracle like after stalking her and hearing her private phone call.
