I am sure that George means "coming from above relative to the
horizon". Which is a fine statement to make, IMHO. I do find it odd
that you were apparently unable to make this inference, given your
next paragraph:

That is possibly what he meant, but I think you're trying to interpret
what he said in light of your own understanding. That's a common
mistake that instructors make and it hides the fact that the student
really *doesn't* understand.

Odd words or phrases used to explain something can often give a clue
that the mental model is wrong. This "relative wind coming from
above" sets my detectors going off. Where the relative wind is coming
from relative to the horizon is irrelevant.


[an accelerated stall.] Yes, he certainly is, and he said as
much.

Where?
