Possibly this was sarcasm, but I’ll bite just in case. There is quite a lot of scientific research that informs modern aerospace engineering:
https://phys.org/tags/aerospace+engineering/You’ll find similar physics research for example in nuclear power, optics, quantum computers, telecommunications, engines.. all kinds of engineering really. Chemistry is also quite relevant and there are new, stronger materials being engineered all the time based on research.
It’s definitely not all just 1900s physics driving everything, even if you say that for some reason anything researched then doesn’t fall under the 80% of science that doesn’t work (which GP didn’t).
