re: #248 Mike Lamb
I think another issue would be whether the waiver was actually “knowing”. You can put all the risk language in the waiver you want, but if there was no way for passengers to know the sub was only designed for a depth of, say, 2000 meters, and that was expressly mentioned in the waiver, the waiver doesn’t mean shit.
Again, that is the sort of thing that it is up to the passengers to ask. This is not a holiday cruise or amusement park ride with minimal expectations or chances of risk under normal conditions. This is untested, unrated technology under extreme conditions.
