This guy was clearly crazy, made suicide and bomb threats, and was stopped before. There was also little to no real chance he'd make it; this isn't like swimming the English Channel, and even then those attempting it had boats & support. The imploded submersible guy was well known in the industry to be cutting corners and playing fast and loose, but had done successful dives in the past, and had a boat there to support him. Playing fast and loose in a sub will eventually get you killed -- and it did -- but there was at least something of a track record.
