Yeah, I hear ya. They say that water is so laden with Nork mines, unexploded war ordnance, and all other manner of hazards, that fish will walk by on land before they'll swim through it. The one big hole (pun somewhat intended) in this episode is the explanation that they were firing at a flock of birds beforehand. Radar operators are trained to filter out that sort of thing. It won't surprise me if they conclude that the Norks baited them into a trap they had set up for any vessel that could get drawn in from afar.
