Not from within the metal hull of a partially submerged submarine.

I work offshore on occasion; when in areas with excellent coverage, you'll often have (spotty) coverage on decks below the waterline - the signal bounces off any reflective (to RF energy) surface and finds its way into lots of nooks and crannies where you wouldn't expect to have reception.

Typically such zones are small and prone to interference, if you move just a little bit your coverage could disappear and reappear. The same happens in the 'urban canyon' of big cities between the high rises.

Even so, the default is that if you're in a hull you should not expect to be able to get out, and a submarine especially has a nearly cylindrical hull with only a very small hatch up top and this particular one has a few windows.

Sure, but a submerged sub shouldn't have any nooks and crannies that leads to the surface.

True, but a submarine does not necessarily travel submerged.

> Also worth mentioning is that the police were very quickly charging him with manslaughter - so quick, they probably had indications something was wrong with his statement even before the sub was raised.

From the linked article:

> Mr. Madsen’s new account was only disclosed on Monday, with the approval of both the prosecution and the defense, although he had given it in court, behind closed doors, on Aug. 12

Sounds to me that his statement was exactly the reason he was charged with manslaughter.
