Someone described it as having about as much room as a small SUV. It was one cylinder. The sub guy I follow on YouTube said that carbon fiber shatters when it fails. When it failed, they didn’t live but a few seconds. Probably long enough to recall the number of times “death” was mentioned in the waiver. (Three times.)
A lawyer I just listened to mentioned enough evidence to indicate gross incompetence and negligence on the part of the company that owned and operated the sub. Not to mention they didn’t want any “fifty-year-old white men” involved.
In reality, you’ll have the surviving $Billionaire families suing an entity with no real assets.
