Over the years I have had a few, very few, people who fly regularly, wh0,nevertheless, continue to be afraid of flying. I think in every case they flew on the aisle seat. If they don't fly on the window seat, they really can't have the experience of flying on an airplane. Airplane trips might be a little different than being stuck in an elevator because the plane can bounce around from time to time, perhaps scaring the person all over again. A stuck elevator is unchanging and, therefore, easier to get used to.
