I never have the problem in the Kiwi when I'm flying, even when doing
aerobatics in an Extra 300 (Yes, Viperdoc, it's got your plane in it!
Actually Patty Wagstaff's, but I digress...). I have felt queasy
*watching* others fly, though, especially ham-fisted newbies who over-
control in all three axes...

It is well known that it's unusual for the person controlling a vehicle to
develop motion sickness, even if he might otherwise be prone to it. As far as
I know, no definitive explanation for this exists, although there are many
theories. Indeed, motion sickness itself, when caused just by _looking_ at
something, is also somewhat of an unexplained mystery.

I became nauseated watching _The Blair Witch Project_, not because it was
scary (it wasn't), but simply because the actors had no training in
cinematography and could not keep the cameras still. And apparently the movie
was edited to remove the worst of the camera movements. It also made some
people sick in theaters for the same reason.

We had one little girl puke when her dad (a non-pilot) simply could
NOT stop over-controlling the roll axis. Back, and forth, and back,
and forth, and...**urp**.

She didn't just look away? Perhaps she didn't know why she felt sick. It
does sneak up on you.

How many times can he overcontrol before he realizes that he is
overcontrolling?
