Vertigo comes from the inner ear. That's where your balance comes from. I had to study it in depth while I was in flight school. It can be caused by illness and I don't know anything about that other than it makes you sick to your stomach. In the case of flight vertigo it's from not being able to see the horizon. It is actually caused by your balance telling you something that don't jive with your eyes or what you feel. For pilots it comes from flying in the clouds where you can't see the horizon, if the plane banks for 30 seconds or so then with no ground or sight for reference that unlevel situation becomes level to you. Then when you return to level you will swear that you are leaning the other way. They tested it in the classroom with a chair with an electric motor that turned the chair around real slow. Someone would sit in the chair with blindfolds and the chair would turn. After 30 seconds or so the guy running the chair would slow it down to 1/2 speed. About 1/2 the people would fall out of the chair because they thought it had reversed direction. I have had it in flight and it's a powerful sensation. That is what crashes most small planes, the pilot gets vertigo and he thinks he's flying level and ignores his instruments because he figures they must be wrong and heads straight into the ground.
