It's not JUST safety. The joke may be perfectly safe. But small
aircraft ARE dangerous and it's normal to worry somewhat about one's
safety while aboard. I always felt it was my job as captain to make my
passengers feel MORE safe, not less safe. Sure, ANYONE can scare a
passenger. Frankly if someone pulled one of these stunts on me, I'd
probably desert him as a friend and associate. These stunts have no
place in an airplane. Get your kicks some other way.
