It is hard to imagine what the people trapped inside that submersible are going through on the bottom of the ocean as their time to live ticks down to just a matter of hours. The group, four passengers and a pilot, went missing on Monday during a trip to see the world's most famous shipwreck. And it's incredible to think that after 111 years, The Titanic may claim yet more victims. 

A CBS reporter went down into that sub for a story and gives a first-hand look at what it's really like inside the craft. The thing that struck me most about the video is how little room there is to move around or even possibly stand up. As a claustrophobic who can't even survive a few minutes inside an MRI machine, I can't imagine this fate, which is perhaps not worse than death but sadly, a possible prelude to it.
