Any structure, be it a step ladder ot the Eiffel tower, between the soles of my feet and the ground, can cause vertigo.
In an aeroplane, absolutely no problem, rather strange.
The kiss of death is something that moves as well as being in ground contact, such as a ferris wheel or the london excrescence. I think that the slow motion makes matters much worse.
I learnt once, to my cost, that the unpleasant sensation associated with moving vertigo is infinitely worse if experienced with a rather serious hang over!
