Indeed. We were subjected to this in initial training, which meant that I had a chance of recognising it. Does everyone have this experience today?
It may be but the Coriolis illusion is normally the result of abrupt head movement after being in a steady state turn for some while.
That is the demonstration as described by Roscoe, but I do not think the physics requires the steady state to cause the illusion.
Before posting I looked at a lot of sites about the Coriolis Illusion and there seem to be two distinct descriptions, copied almost word-for-word from site-to-site. The first is like yours and the second like mine. Wikipedia, for instance, is like mine.

Whatever the cause it is unlikely to be new, but how prepared are helicopter pilots these days, to cope with the somatogyral illusions?
