Anyone following the titanic sub story? Thoughts?

It's horrible

5 rich men in a submarine on route to see the titanic wreckage get lost in the ocean. Search teams must rush to find them before their 12 hours of oxygen runs out.. almost sounds like a Hollywood movie but then you realise this is happening in real time.

Expert say their survival rate is at 1%. In other words this is retrieval mission rather than a rescue mission.

Update: The five men have been confirmed dead by the coastguard. Debris found at the scene is consistent of a catastrophic implosion of the vessel, meaning they were killed instantly.
Rip to the victims and condolences to their friends and family.
