No, it isn’t. The relevant accelerative forces - thrust, drag, and lift - are all ‘air referenced’, for want of a better term. (And as has already been pointed out, the change in velocity is the...

Might as well give up, folks, there’s no point. It’s like a sort of religious zealotry. Doesn’t matter how simply you explain it or how much you appeal to logic and reason, you’re fighting an...
