lederhosen; I take your point, but don't forget these were probably travelling at the speed of the sub. 15 kts maybe, and possibly not into wind. As you are no doubt aware, the "dead man's curve" is both speed and height definable. 15 kts/400'. Dunno; maybe if reaction is fast enough. Either way, you are gonna die. Break your neck, drown, freeze. Plenty of options, the one about being rescued not really figuring.
