Pray for missing Titanic Submersible

I guess there was something to find.

Anything wearing pants and a shirt is probably presumed to be human.

It was my understanding that the massive amount of heat that would be generated in an implosion of this magnitude would basically vaporize anything other than hardened metal.

That was my understanding as well which is why I thought it was weird when it said they might have found remains.

I have to admit I'm always surprised when people believe dumb jibber-jabber and then actually argue about it. Honestly it's embarrassing.

So...this was all based on the presumption of an implosion of a submarine. Think of a pressure hull that is 200-350 feet long, and 25-40 feet in diameter. In that scenario, an implosion would (and in the case of the USS Thresher did) produce a "water ram" at the point of failure that would compress the remaining air in the cylinder (hull) as it advanced, heating the air to extremely high temperatures, so that the dual effect of the high temperature and advancing water ram would reduce a human body to an unrecognizable and almost nonexistent lump of...whatever. If human remains, or anything resembling them, were ever found when the wreck of the Thresher was found, I've never read a single word about it. 129 souls onboard, and not a peep about remains.

Edit: Depending on which analysis you believe, the USS Thresher imploded in the 1900-2500 foot range. The Titan submersible was, by all accounts, somewhere in the 10,000 - 12,500 foot range when it failed. So roughly a factor of 5 deeper and thus higher pressure.

At those depths, and those pressures, all that is certain is that survival is impossible. All other assumptions are based on a very small data set. Thus, the assumption that no recognizable remains could, or would be recovered from the Titan wreck.

Could remains exists? Well, apparently yes. It would be extremely reckless for the USCG to suggest so unless they were relatively certain what they were seeing. So let's assume the answer is "yes"? If so, then how, at those extreme depths and pressures?

Small vessel...small interior volume...minimal heating of a small air mass...and the water ram didn't travel very far before it encountered more water at the same pressure. In Redneck Engineering Terms, it was more of a "pop" than a "bang". Small vessel = Small implosion.

It'll probably be a year...maybe more...but it will be interesting to see what the medical experts say about how the Titan 5 perished. Although honestly, at this point, it is nothing more than morbid fascination with how people die at those extreme depths that keeps most folks interested. I spent the better part of 20 years cruising around in "non-survivable" water, meaning that if we went down, it would end with the proverbial "bang". I trusted my life to the good folks at Electric Boat and Newport News. I trusted them, and I survived.

The last 4 who trusted Stockton Rush did not. That's really all the world needs to know.

RIP.

Lost Titanic sub: Vessel used Electrical System Designed by College Interns: Report

The Titan submersible that imploded en route to explore the Titanic was using an electrical system designed by college interns, according to a report.

“The whole electrical system — that was our design, we implemented it and it works,” 2017 electrical engineering graduate Mark Walsh told WSU Insider in February 2018. “We are on the precipice of making history and all of our systems are going down to the Titanic. It is an awesome feeling!”

I hate arguing on the internet. Forgive me here. The problem with this obviously made up scenario is that the air in a submarine simply doesn't have enough mass to significantly heat up anything, and no time as well. In theory, yes, you can heat air up to a high temperature. But you're going to have a hard time burning up a 200 pound person in one millisecond with 5 pounds of air surrounded by a limitless and very cold ocean.

I think we should post memes in instead.

It’s better to be “inspirational” than qualified.

I watched a YouTube video today that purported to show the communications between the support vessel (topside) and the Titan submersible. If it's fake, it's a good fake. If it's real, then it gives investigators (and us) a picture of what the last 15 to 20 minutes of the Titan's existence was like. Being a retired submariner, there were things there that gave me chills.

FYI, when you go deep, you get heavier. It's called "hull compressibility factor", and it accounts for the fact that you weigh what you weigh, but as you go deeper you compress, and thus you displace less water = you get heavier. On modern subs, you deballast (pump water out of the variable ballast tanks) as you go deeper to account for that. To a lesser extent, this is a factor for the Titan submersible. If she was heavy when she began her descent, probably in this case due to weights she carried on her frame, she would only get heavier as she went deeper. Food for thought. Those electric thrusters can only generate so many "pounds " of thrust. Again, there are clues in the comms log as to how the thrusters did not generate the ascent rate that they expected.

Looking at the photos of the recovered debris, I noted that the "window" is missing from the front hemisphere. There is no indication that it "imploded", thus it may well have blown out = implosion started at the rear end of the submersible. Again, this matches with the supposed Comms Log of the Titan. Noises aft.

I know what happens at 1000 feet. I have no idea what happens at 13,000 feet, but at 44 psi/100 ft anyone can do the math and see what the numbers are. There's not an engineer out there who can change those numbers, or lessen the pressure any vessel would face at that depth. Stockton Rush messed with the bull, and he got the horns. Sad that he took 4 innocent victims with him. You do not beat nature, or physics, with interns and untested manufacturing techniques. It's a miracle that the Titan lasted as long as it did.

Stockton Rush viewed himself as a modern day version of the Wright brothers. History will expose him as a modern day version of Icarus. He took untested tech to an unsurvivable level.

I have skydived from 12,500 feet...served on U.S. Navy submarines at test depth...taken a hit on an NIJ Level 3 ballistic vest...and performed a PIT maneuver in excess of 90 mph. I survived all of them. In each case, I had established science behind me.

Stockton Rush did not. What he "established" was that you do not go against science. If you do, then you end up as an example for others not to follow.

It is what it is. RIP to all.
