CBS News journalist David Pogue said "The submersible had seven backup systems to return to the surface, including sandbags and lead pipes that drop off and an inflatable balloon. One system is designed to work even if everyone aboard is unconscious,".

It may be possible they are entangled on the ocean floor. Reports are that sonar has picked up intermittent banging noises under the surface in the area where the sub went missing, so that's promising.

Or it could just be a totally crappy design or a scenario like Apollo 13 where everything just went haywire.

Well, I'm not sure "crappy" is the way to describe a one-of-a-kind craft that does something no other craft in the world (that we know of) can do. Like all experimental vehicles, the risk is always high because there isn't a big enough class of similar vehicles to find and cure all of the faults. There simply are no precedents. What was likely the biggest mistake in all of this was opening up the experience for "tourist" travel, but I assume all involved were adequately informed of the risk.

Ive been wondering about this. It does seem like it’s an experimental submersible, but haven’t they been going down to the titanic (and even deeper) for some time now? Were these guys trying to reinvent the wheel, or just trying to improve on design? Or maybe trying to cut corners to make it more economically viable as a tourist industry?

Red flags to me are numerous aborted missions. It has been lost without communication for several hours on 2 separate occasions. Once aborted due to battery failure. There have been successful missions mixed in, but WAY too spotty of a history for me to be willing to literally risk my life.

If it had a long history of successful dives without event, I could understand it.

Apparently 2 former employees had previously shared concerns about hull thickness of the vessel. Neither appeared to be engineers, but that may not be relevant.
Seems the carbon fiber hull was 5" thick, but was supposed to be 7"?
The overall design seems pretty flimsy for that incredible depth (13,000').
Sounds like something a CEO would have control over.
That's what a paper degree at a liberal indoctrination school will get you. At the bottom of the sea.

Claims that it is impossible to using NDT to check for anomalies in the carbon fiber are bogus.
How does Boeing check their Dreamliner hulls?

You should be able to check for abnormalities to a certain degree - but you could never simulate the pressure of 4,000 meters below sea level. That could exacerbate even the tiniest abnormality that you'd never be able to detect on the surface.

13,000 feet alone stops me in my tracks. That's fearsome.

I wish we could and I’ll try. The focus is the tragedy at hand that seems to be about hubris not political affiliation.

We all need accountability in life and it appears Rush chafed at any hint of that in his submersible design.

The ironic thing about the post that placed Rush as liberally indoctrinated is that Rush was a fairly well known GOP money contributor. This of course had nothing to do with the cause of this tragedy.

His arrogance and disdain for oversight because it would stifle innovation seems much more plausible

There will certainly turn out to be an irresponsibility aspect to this, even if it stems from design limits versus reasonable operating parameters.

I hope these men are rescued safe and sound. I do. But I can’t stand seeing them being portrayed as explorers. They are tourists on a glorified sightseeing trip. As a tourist anywhere, you have to use caution. They chose to go sightseeing nearly 2.5 miles beneath the ocean’s surface in an unproven vessel that had a spotty history hundreds and thousands of miles way from anyone could help if tragedy occurred.

As to the “exploring” aspect some are citing, no. There is nothing to explore or discover. The area has been mapped in 3D detail. There are unmanned submersibles that can dive far deeper. Considering less than 5% of the ocean has been explored, it’s not “exploring” to be going somewhere comparatively shallow to see something we already know everything about.

I'm afraid it's over. The emergency oxygen has expired.
Terribly sad. Ill-fated decision all around.

Not that it’s any consolation to the families, but they were most likely already dead. If there was a hull malfunction, they would have died in milliseconds.

The more you read about rhat sub design, it’s crazy to think this was even legal to do.

It was barely covered by the media in comparison but 300 Pakistani migrants died when their boat sank a few days ago.

Hopefully it was a hull malfunction - and I would think that the lack of the submersible would evidence that. It had several ways, including automatic ones, to drop the weight and float to the top - but a crushed hull would not float.

Indirectly, the Titanic adds to its list of lives lost.
Don’t know if you saw this, life is odd

Submersible Pilot’s Spouse Is Descended From a Famous Titanic Couple​

Wendy Rush is a great-great-granddaughter of the retailing magnate Isidor Straus and his wife, Ida, two of the wealthiest people to die aboard the ocean liner.

Since the remote vehicle found debris, it is apparent that this was always a catastrophic event and not a slow death. The vessel broke up.

Coast Guard said hull would have collapsed in 2-4 nanoseconds. Instantaneous death. They would have never even known it was happening.

Seems this is what happened. :(
I have to wonder what were the risks if the vessel were made of high pressure steel rather than composites?

I could not imagine having myself placed inside a metal tube that is to be dropped 2 1/2 miles into the ocean, and then having that tube sealed from the outside with 17 bolts, and there being no way of escape.

Oh, I didn't say I'd volunteer to go down in it. It was a death trap machine, for sure. I was merely commenting that, to me, "crappy design" implies that there is another design out there doing similar things more reliably. To my knowledge, there was no such alternative. Perhaps it's just semantics. For the record, I would have never gone up in one of the space shuttle either (for obvious reasons, in hindsight). Not that I thought the space shuttle was a crappy design, but it's just a terribly dangerous endeavor with 1980s technology (and likely with 2020s technology too). Similarly, there is no safe way to dive down 13,000 feet under the ocean surface - and likely won't be anytime soon.

It was made from carbon fiber, which was questionable. Probably should have went with steel. The CEO admitting he broke rules in the construction of the vessel as well.

James Cameron, who knows a thing or two about this, noted that while carbon fiber is lighter and stronger that steel, it is not stronger in compression.

They say at the depth it was when it is believed to have imploded, it would have imploded at a rate of 1,500 mph or 2,200 feet/second (since this is a sports forum, that 7 1/3 football fields in 1 second). It would have compressed the air inside so quickly that it would have ignited and then exploded, essentially vaporizing the occupants. The total time for implosion and explosion is believed to have been 1 millisecond. The human brain responds to stimuli at about 25 milliseconds. So, they were alive, and then less than one second later, they were vaporized. They would not have even had time to sense it was happening. Nature is fascinating.
