The Implosion of a Shipwreck

The submersible is recovering with a lot of the wreckage. The question is, was there anything? Was there any indication in advance that it was going to happen? And how scary would that have been? Probably not. There would be no wait time to process what was going on. It just would have happened. I've never seen the sopranos, by the way. I just know the end.
