I would really love to know the billionaire's thinking.
Why go on that crappy homemade sub when you have the means to have a better experience in a Triton.
With the means he has, why wouldn't he want the best possible experience, instead of what he actually did?

If I had a billion and had a desire to go to the titanic, I'd go on a sub that I read is the only submersible ever to be certified to unlimited depth.
