A few years ago now, I remember a parent seeking advice on how to reassure his young child that flying was perfectly safe. We suggested that he brought the young 'un just to watch aircraft take off and land for an hour or so (the little boy was scared the wings would fall off, apparently), after which we found someone who would let the boy sit in a PA28 to see what it was like.
Grateful parent came back a few weeks later saying it had worked a treat!
