To quote the CBS reporter who recorded an earlier journey with them, as he read the waiver form¹:
>...An experimental submersible vessel, that has not been approved or certified by any regulatory body, and could result in physical injury, disability, emotional trauma, or death. Where do I sign?
Probably not enough of a disclaimer, especially if they had people read and sign it once they were already miles out at sea. The passengers were technically advised of the risks, though.
