I wonder if a hot air balloon would have the same effect? Something
about zero airspeed and no engine noise at altitude that strikes fear
into the heart of a fixed-wing pilot?

Actually, a pilot friend of mine just took his first hot air balloon ride
last week. With no history of fear of heights he experienced vertigo in a
bad way. And his wife had to sit down on the floor of the basket.

Their story was enough to remove THAT particular experience from "the list"
for me...
