The somatogravic illusion is s utterly convincing, it is the reason we even have IFR and VFR (I for Instrument, V for visual flight rules). Any dummy can watch the instruments, instrument rating means you are convinced that the instruments are correct, and that your vestibular system (sense of balance) is incorrect. Human orientation senses are very ambiguous, it needs input from other sources to disambiguate it. A subtle cue can be all you need to reinterpret your senses to tell you that your orientation is changing badly.,(reply>), @YourMJK Oof, when I was a kid the pilots of a belarussian plane also let me hold the controls, though they said it was on auto pilot. Good thing I didnt die I guess,(reply>), @Ragnhild your inner ear canals are full of liquid that sloshes against fine hairs as you change direction.  If you keep turning in that direction the sloshing fades so without visual cues it seems like you are slowing down or even going straight.  When you in fact do stop turning it now feels like you are now turning in the other direction.,(reply>), IFR means "I Follow Roads".,(reply>), @Anonymous <br>Of course dizziness is still a thing, but you can end up in a dangerous spiral without getting noticeably dizzy. That’s the problem: the effects on your vestibular system are too subtle to notice, especially when you have no visual cues to tell you that you’re spinning.,(reply>), @Ragnhild Why? Is dizziness not a thing anymore?
