I uploaded my copy of the CIPIC data and docs to
http://ambisonics.dreamhosters.com/CIPIC/
and hacked together a readme.md based on the original home page for the data

I apologize in advance for the lack of aviation content.

We were not discussing spins, either upright or inverted.

Para: Stefan Schreiber
It sounds like a description of how to come out of an inverted
(upside-down) spin.
That would require a pull to get the nose down.
In a spin, one wing is in the centre of the rotation and does not
have lift

'pull down' ??
You either 'pull up' or 'push down'...
And if you're in a spiral, there is no need to recover
airspeed - it will be

Not usually. But if they're in a hard hitting, oscillating, theatre,
with some 120dB bass, some of which is conduced via the seat...

Most of it has to do with the vestibular system, yes. But not all of it.
Some of it also has to do with audition as well.

When the conflict is between auditory and visual, usually the
visual cues will dominate.

Just stupid: within a confined headphone cover, it's going to be a

Such a good point. Thank you.
I'm too rooted in the film and TV world, where a visual anchor
invariably exists.
