KNX In Depth: Man who took a trip on the Titan submersible says he's heartbroken--Doctors told a man he was going to die until different doctors made a surprising discovery

The tragedy of the Titan submersible has gripped not just the U.S. but the world. Five people on board killed in what appears to be an implosion. We go In Depth with a man who rode on the Titan just a couple of years ago and knew two of the people on board.  What if doctors told you that you were going to die and there's nothing anyone could do about it? But what if you later found out they were wrong? One man from LA went through that horror and he'll tell us about it.
