In Jersey European, we used to do a fear of flying course in a 'Shed', (Shorts 360), I kid you not. I was an extra pilot and I stood at the front of the cabin doing a running commentary over the PA about all the noises of the 'plane and the flight, and what was going on.
It seemed a bit unfair to the frightened passengers to me, but I suppose it was the least claustrophobic cabin, being square in section.
