Great analogy. Reminds me of a story.
Before and during WWII, the father of a friend used to haul timber and some goodies to/from the Bahamas/Nova Scotia, using pick-up Bahamian crews. The only thing his crews were more afraid of than being away from home on such a long trip was being in the water on such a long trip. One trip, somewhere off New Jersey, a periscope appeared only a few yards away, pointed right at them and the whale-like thingee it was attached to breached the surface moments later. Achtung, yep, they were German. "Vee blow your boat up," said Herr Kaptain (or whatever he was called -- he spoke good English) "so bitte get in your life raft so vee don't hurt you. And take mit you vater und food und flairs."
Lengthy discussion about vhat I mean what was on the boat, no arms, just my friend's father, his crew and his dog. Oh and yes, a little rum which he would gladly hand over. With a salute, Herr Kaptain said he was ... wait for it ... "just following orders." Finally friend's father, his crew and dog got in the dinghy and rowed a safe distance away. The dog went to sleep, the crew trembled, and friend's father got philosophical. "Oh well, that's war for you."
The sub tried four times to blow his boat up. Missed all four times. Friend's father had time enough to sketch the little sailing vessel while he watched. Finally success on the 5th try. "Vee like you. Can vee take you anyvhere?" asked Herr Kaptain as the boat nosed down. "Nova Scotia would do." "Sorry, vee not go zat vay. Good luck to you."
Friend's father, trembling crew and sleeping dog drifted for two days and finally hitched a ride to Ireland.
True story.
Has nothing whatsoever to do with cdex nee loch though so it'll prolly be zapped.
