On why the missing vessel has not yet been located
We really have no idea. I mean, the waves are six feet high. It's all whitecaps. The sub itself is white.
The more i read about this the dumber it gets.
At least there are failsafes to bring it back up. If it wasn't too deep if i understand correctly
yeah, but then you need someone on the outside to open 18 (!) bolts, before you can exit. no way to open from the inside. so you'll probably suffocate anyway.
