When searchers are desperately looking for any signs of life, any sounds can be mistaken for a clue.

Maybe they had early warning signs that something was wrong with the sub. Maybe it imploded later. Dunno.

I was thinking that maybe the billionaires son killed everyone else in the sub, so that he could save himself by having 2 weeks of oxygen, and a ready food supply if needed.

@fury @Girlparts coulda been anything. Lots of things make banging noises underwater.

Could have even been hundreds of miles away.

Heck there's recordings of artic ice cracking from the middle of the Pacific!
