> Never said as much. OP asked why all planes since the 70s look about the same. It’s because there isn’t a sustained budget for experimentation. Bullshit. There is tons of money for innovation, every single manufacturer is trying to squeeze 1-2% efficient improvements across the board. To say there is no funding for innovation is hilariously ignorant. > Never said as much. It’s not exactly groundbreaking for entrenched supplies to cease innovating and focus on extraction. Cool, can you show me what numbers you're looking at that even hint that these blended wing bodies are better than contemporary commercial designs?

> Bullshit. There is tons of money for innovation I heard almost the same out of a Lockheed executive about launch about a decade and a half ago. A dollar of R&D can travel differently at a cushy corporation than at one in competition. > can you show me what numbers you're looking at that even hint that these blended wing bodies are better No, I have never defended this design—I have no specs. A better question is why you’re so convinced this optimum is the global one.
