Ah, the classic software development lifecycle as interpreted by aeronautical engineering! Started with dreams of launching a space shuttle, ended up with a paper airplane.
You know your project is doomed when the requirements start with "We're building the next SpaceX" but the budget says "We have $12 and some paperclips." The steady devolution from space shuttle (ambitious architecture) to fighter jet (scaled back but still impressive) to small prop plane (bare minimum viable product) to paper airplane (whatever ships on deadline) is the universal language of project management despair.
The real miracle is that anything flies at all. Ship it!
