Rocketry, in particular launch vehicles, appears to be one of the fields where Murphy's Law plays a big part, where "good enough" causes a lot of problems. My guess as to why this is: physical intuition fails at 140 dB, 1.5 million pounds of thrust and high temperature. There's just not a lot of training data, either. This is exactly the type of situation where LLM based "AI" doesn't work well.
