I agree with you with it on the scale example. Thanks for the detailed explanation. Where we disagree fundamentally is that you are finding that the analogy is wrong. But wrong for that? For the scale example it is wrong. For the aerodynamics testing on a little model it is not. From that, I conclude that it _can_ be useful, which is a different claim that it _always_ is.
