Back to your original question ... I will supply an answer of what
"is" ... I was (as you asked) taught during my ab initio flight
training to keep my head and body in a straight line, and not bend at
the neck, neither away from nor toward the direction of the turn.
Swiveling the head and/or moving the eyes to watch the patch of sky
you were heading toward is taught (of course). Swiveling the head in
the other direction is also taught to look for possibly converging A/
C. However, one is taught to NOT bend your neck during turns. The
argument is made that doing this makes you more prone to
disorientation, sloppy flying, and a phenomenon called "the leans"
after prolonged turns or during instrument flying.

And is this argument supported by scientific data, or simply folk wisdom? Why
would it be the recommended behavior for identical turns on a motorcycle, but
not for flying? Who's right, and why?

Now now ... all you've done is substituted "And" for "But"! So I
guess I should have said "No 'if's', 'ands', 'ors', 'buts' or
'maybes'...". You asked how it's taught ... and that's how it's
taught ... give your head a shake and listen.

Why don't you write to Transport Canada and ask them for all of the
"scientific data" you seek? Every couple of months this agency
publishes a newsletter outlining the science (physics, and human
flight physiology for instance) behind a number of the basic
principles taught during flight training, and what happens when one is
forgetful, ill-trained, or foolish and/or argumentative enough to
disregard what you have been taught. Where I was trained you learn it
this way (from the "Flight Training Manual" - "Exercise Nine -
Turns"), or you don't fly. And from experience I can truly say that
doing it the other way does, after a time ranging from many seconds to
a minute or two, even at a gentle bank angle, lead to a very
uncomfortable feeling that my instructor told me is called "the
leans". You don't want to fly with the leans.

Also, I am not conceding that there is anything "identical" about
motorcycles and flying. I can think of so many things about the two
that are different it is not even worth comparing them any more
(although it did help a little bit around 1900 to compare the two, but
I wouldn't want to try to fly the Wright Flyer!). Nor is this a
motorcycle newsgroup. Why don't you trot out some real mathematical
physics right here and now and prove to all of us YOUR claim that they
are identical? Until then your comparison is a specious red herring.
Perhaps you are wrong, and BOTH claims can be correct, huh? This is
possible if we disregard your premise that they are identical.

Again ... the answer remains the same ... neck straight ... not bent.
It's safer this way, has been studied carefully (see above). The
onus, or burden of proof, to make any claims to the contrary, lies
entirely with you.

So get to it ... or enough already ...
