Some of the quotes:

RUSH: You know, there’s a limit. You know, at some point, safety just is pure waste. I mean, if you just want to be safe, don’t get out of bed. Don’t get in your car. Don’t do anything. At some point, you’re going to take some risk, and it really is a risk/reward question. I think I can do this just as safely by breaking the rules.​

Last year, at the end of a Titanic dive, OceanGate had trouble getting the sub back onto the ship. Those poor mission specialists …they wound up spending 27 hours in the sub.

POGUE: It seems like this submersible has some elements of MacGyvery jerryriggedness . You’re like, “we bought these handles off camperworld.com”. You’re like, “these thrusters are modified from some other purpose.” RUSH: (cont’d) So, the pressure vessel is not MacGyver at all, because that’s where we work with Boeing and NASA and the University of Washington. That part, once the pressure vessel is — you’re certain it’s not going to collapse on everybody, everything else can fail. It doesn’t matter. Your thrusters can go. Your lights can go. All these things can fail. You’re still going to be safe.

Gotta tell you—this was different. I mean, here are just a few choice excerpts from the waiver you have to sign: “The experimental submersible vessel has not been approved or certified by any regulatory body. Any failure could cause severe injury or death. The support vessel is an industrial vessel not designed for passenger operations and present many hazards, including…property damage, injury, disability, or death.

KYLE: These triple weights, we call ‘em, are hydraulically driven. So we operate ‘em inside, doesn’t take any electricity, can be done manually, and those drop away and gain us a lot of buoyancy. Dropping that much weight onto the sea floor means the sub starts rising.

KYLE: Ah, so, we’ve got these weights here on the side, these are roll weights, we can actually roll the sub and those come off, and that gains us some buoyancy to come back to the surface. These are pipes that sit on a shelf that juts out from either side of the sub, held in place only by gravity. If everyone inside the sub shifts their weight to one side, the sub tips enough to let these pipes roll off.

KYLE: These bags down below, we drop those off using motors and electric fingers.

OK. But what if the electronics go out, and the hydraulics fail, and everyone inside has passed out unconscious? KYLE: There’s fusible links within these that actually can dissolve and come back in time if it’s drop off.

Fusible links are self-dissolving bonds. After 16 hours in seawater, those bonds disintegrate, the weight bags drop off automatically, and you go back to the surface.

And even those four systems aren’t the end of it. The sub’s thrusters can also push it up; the pilot can jettison the sub’s legs as dead weight; and there’s even an airbag they can inflate to provide buoyancy.

All told, that’s seven different ways to get the sub back up to the surface.

GRAPHIC DESCRIPTION OF DECOMPRESSION ACCIDENT:
Medical investigations were carried out on the remains of the four divers. The most notable finding was the presence of large amounts of fat in large arteries and veins and in the cardiac chambers, as well as intravascular fat in organs, especially the liver.[3]: 97, 101  This fat was unlikely to be embolic, but must have precipitated from the blood in situ.[3]: 101  The autopsy suggested that rapid bubble formation in the blood denatured the lipoprotein complexes, rendering the lipids insoluble.[3]: 101  The blood of the three divers left intact inside the chambers likely boiled instantly, stopping their circulation.[3]: 101  The fourth diver was dismembered and mutilated by the blast forcing him out through the partially blocked doorway and would have died instantly.[3]: 95, 100–101

Coward, Lucas, and Bergersen were exposed to the effects of explosive decompression and died in the positions indicated by the diagram. Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door.[3]: 95
