If you ever do anything "risky" you'll fill out a similar form. Go look into skydiver liability forms, they also mention the possibility of death or injury. I suspect most people embarking on expensive & risky adventures are used to these and based on previous adventures being alright just sign the paperwork without reading or thinking about it deeply.

I'd be running the moment I read this paragraph:

>2. A portion of the operation will be conducted inside an experimental submersible vessel. The experimental submersible vessel has not been approved or certified by any regulatory body and may be constructed of materials that have not been widely used in human occupied submersibles.

If you don't, you knew and accepted the risk.
