Have you ever flown over a lake or over the ocean? A friend recently flew in from San Diego. He had been in the navy and he had always owned boats, but he had never before observed what he saw now from the air. He was on the ocean side as the plane took off from San Diego, and looking down he saw this little thirty-footer coming in the opposite direction. He noticed the wake of this little ship and watched it widen, and nothing interrupted it. When his plane turned inland he was flying at three hundred miles per hour, but looking back he realised that this little boat – doing maybe thirty knots – was troubling the entire Pacific. As far as the eye could see this wake was moving and nothing could stop it and the occupant of that boat was totally unaware of what he was doing.108 ¶12
