Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

MODERATORS
I had no idea they are still pulling up remains.
The US has already spent millions on search and rescue (it surpassed 1.2 million even before the wreckage was found).
Anyone else love that the ultra rich can book quarter million dollar trips on ridiculous vehicles and then still cost the taxpayers millions.
If you are wealthy enough to book a trip into space or to the bottom of the ocean, then you need to be paying (in advance) for whatever resulting expenses might come out of that....or be required to carry the insurance that will cover it. It's stupid that taxpayers have to pay for this and that the Coast Guard is STILL AT IT...racking up more costs.
To be a little more clear about the cost:
Pilots must fly a minimum number of hours, regardless of what is going on in the world. Adding a mission (such as search and rescue) to those flights is trivial because the man hours, fuel, and maintenance are already allocated.
They may have added to the plans but a lot of the cost is already paid when these things start.
That's a single narrow example and does not accurately account for the taxpayer cost of doing this.
When it's reported that the government estimates the cost to be 1.2 million (and that estimate was as of some date back in June - source: https://en.as.com/latest_news/missing-titan-submarine-how-much-does-the-search-and-rescue-mission-cost-and-whos-paying-for-it-n-2/ ) I understand that to mean over and above what their daily/weekly/monthly/quarterly/yearly predictable/normal expenses are.
It's part of their mission.
Nothing in that article implies it's over and above their normal budget. It doesn't say either way and the Washington Post article it referenced is paywalled.
Besides this being a large part of why we have the coast guard in the first place, this is a way for them to test their training in a real world mission and see how it works and how it doesn't.
People don't get this about military exercises and spending. They would already be doing those things and spending that money. Might as well use it when the opportunity arises.
Also, there's a pretty good chance that data from the imploded submarine can go towards making future submarines safer. But it's harder to get that data without recovery
It's not a new unproven technology, there's no "data to help future submersible". They CAN make it safe, they're ADVISED to make it safe, they're PROTESTED to make it safe.
But they CHOOSE not to because it's cheaper.
Everyone in-the-know knew it was bad and unsafe and will probably ended in tragedy. They speak up, they protest, and they got punished by the one in charge.
Really
You really want me to think that engineers won't find it useful at all
In some cases that's exactly what happens. This was a known scenario and the failure was predictable.
It would have been different if they followed all industry standards and the sub still failed - that would produce valuable data that could contribute to making our understanding of the science, as well as prevailing industry standards, better.
In cases like this you can gather all the remains and data you want, and analyse it, but only if you want to confirm what we already know - reproducing observations and confirming hypothesis is an important part of science, but everything costs money, and at some point you need to triage the studies you want to put money into.
They can still learn something from the materials by looking at how it failed (mostly because the frequency of tests of larger objects at these pressures is limited), but there's not likely going to be anything surprising, just another data point to help calibrate some material science formulas
Everyone knows exactly how it failed.
They used GLUE to stick carbon fiber to titanium.
All three of those components behave very different under pressure.
Every engineer warned them against the use of carbon fiber and the bonehead CEO insisted because he liked it.
It's literally an ego trip that got 5 people killed.
Obviously it would fail, yes, but where the failure started and how it propagated can still be interesting. There's a reason new car models get crash tested, you still want to double check the simulation results. Submarines don't usually get crush tested because they're built with huge safety margins instead, bigger margins than you can put in cars
What are you even talking about?
There is no technically beneficial reason to using carbon fiber in a submarine hull. It won't happen again, and it shouldn't have happened in the first place.
It's like making a car out of Swiss cheese, it's just pointless.
The data is not important.
Do you think the only place it would be useful is for other submarines? It's still materials science. Any place those same materials are used could in theory benefit (again, probably not anything notable, but data on how it behaves in extreme circumstances can be useful anyway)
Not the guy you replied to, but... Yeah? There's not a lot of valuable data in that wreckage to be gained. At least not any data that wasn't already anticipated, known about, or already tested prior. Like the previous guy said, a multitude of experts said it was a bad idea. People who worked for the company and spoke up about the issues where fired.
The entire internet mocked the situation because the man had the hubris to think he knew better than decades of scientific and engineering testing and safety of the materials being used. Many engineers even sent letters to the guy telling him to not use certain materials because they are and have been known and proven to fail at the types of pressures, temperatures, and environment he wanted to take them too.
The only valuable data that I can even image being in that wreckage is figuring out what exactly failed first, the window that wasn't rated for that pressure. Or the carbon nanotube hull that engineers already knew would fail since carbon nanotubes are not good at repeated exposure to stress and microfractures and breakages.
There really isn't that much data to be gathered here that hasn't already been tested and proven multitudes of times before. Except maybe seeing how well the game controller held up if they can even find it
I mean kind of... it's like trying to make a kamikazi plane safer. Literally everyone with a shred of knowlege knew it was going to fail and told him, he just did't listen.
It sounded to me like it was more of arrogance ('I know better than everybody else') than cost cutting. Although the part about not getting the design certified was probably for cost cutting and time saving reasons.
You mean that otherwise just fly around in circles despite a supposed pilot shortage? I'm surprised.
Of there's no legitimate reason to fly, then yes.
