What really bothers me about the coverage of this, and I'm not totally anti media etc, was that nobody mentioned on the fact that the tracking system lost contact also. It was only mentioned that the communications was lost, if there had of been media mentioning that the tracking device also lost contact, I think a lot of people would have recognised straight await that it was a critical collapse. No deep gauge devic…

More than that, one report mentioned the US Navy notified the search teams that they heard an explosion Sunday night and used it to limit the search area. The US Navy has literally has experience detecting underwater explosions (see project Azorian). It's not guaranteed of course, but any loud sound near the point of contact loss seems pretty open shut. Imo, it made a more interesting story in a slow news cycle. How…

100 Americans die on the road every single day on average. Your odds of dying in a car over a lifetime are about 1 in 100.

I am curious how we (the society) justify the shared costs incurred in searching for people involved in such a reckless mission.

Real-world training for the newbies, exercise for the journeymen, and teaching moments for the experts. That alone is worth my tax dollars for keeping a robust search and rescue force. At least some of the CEO's estate should go to paying for it, but pay out to victims' families first.

Agreed. Hopefully, this will result in a requirement for "black boxes" or "flight recorders" for this type of recreational/tourist endeavour going forward. They aren't going to prevent the accident that just occurred, but they provide valuable data to prevent future accidents.

About 1000 children died of malaria yesterday. 1000 died today. And another 1000 will die tomorrow.

What the heck happened to that "photonic shield" that Bill Gates' foundation was working on to zap mosquitoes with lasers? It's been years now. Seems like a good idea and they successfully prototyped it.

He's still busy microchipping everybody in the west, you know..

> How many people died in car accidents the last few days? Car accidents (not involving anyone of note) sadly aren’t novel or newsworthy anymore. A submarine, with people potentially trapped onboard, with limited oxygen, as rescue teams race to the dive site, unfolding in real-time, isn’t exactly something that happens that often.

Add an eccentric CEO operating against everyone's advice, some rich passangers, and it's a dream for the media.

Oh yeah. The media. How convenient. Nobody would have an interest in this if it wasn't for "the media" pushing for a story.

It's an interesting question. (One of very few on this subject that are really interesting.) Those who cause progress to happen to some extent have to have something in them that causes them to ignore conventional wisdom. Because they're swimming against the current. And if they succeed it may well pay off, both in credits and financially. Montgolfier brothers, Lilienthal, the Wright brothers and so on, and that's ju…

This makes me wonder how we went from Wright brothers to commercial flight. Despite being the longest Wikipedia article I've ever seen the Wright Brother's wiki doesn't seem to cover it. Maybe it's a poorly defined question.

Florida man [1]. More seriously, you have to remember that this was in a time before there were a million rules, regulations, and lawsuits for everything. The first commercial airline was a man with a plane, likely largely "self built" (whatever that means in a time before aviation industrialization), who started offering flights in Florida across a peninsula. It worked, it was profitable, there was a market - commercial aviation was born.

600 refugees drowned in the mediterranean and the captain of one of the non profit rescue vessels operating in the mediterranean is facing 20 years in prison. barf.

Both media reports are vanity. They don't impact the reader, don't change society and have no repercussions. Both are read for (different) emotional value. People don't change their life or opinion because of either of them.

While I agree there is a fair amount of indifference when it comes to consuming media. However stating it as zero effect is far from true. There are several examples of powerful journalism having profound effects on the general public. And repeated coverage has been demonstrated to be capable of changing opinions.

In the case of the refugee boat—but not so much the submarine—it occured because of a policy choice of the leaders of many news observers. These leaders have the power to prevents disasters like these. And media coverage has been shown in the past to be able to influence leaders in making some policy changes.

Your intuition is spot on, carbon fiber is much better at tensile loads than compressive loads. Tensile load capacity is pretty much the resin that keeps the fibers from moving. The most I could find about the design > The entire pressure vessel is comprised of two titanium hemispheres, two matching titanium interface rings, and the 142 cm (56") internal diameter, 2.4-m (100") long carbon fiber wound cylinder – the l…

It's wild how carbon fibre is a insanely powerful in it's application yet it's misused. I'd like to say it's caveat being as you mentioned but honestly, given then community in this field, even the technical diving alone. Someone must have said it to them. Thanks for some numbers, maybe tomorrow will play with the simulations to determine the AP's that could collapse the craft. The titanium hemispheres are probably t…

There is a video going around of the lead guy saying (obviously before this incident) something to the effect of “I will be remembered for innovation and the rules I broke, I was told not to build using such and such materials and I’ve proven people wrong”.

The most troubling thing about this to me is Stockton Rush’s cavalier attitude toward ageism [1]. In considering young college graduates as uniquely “inspirational” he set them up for a lifetime of guilt. I don’t think age or race has any place in inspirational calculus. I’m uncomfortable with how comfortably he dismisses submariner veterans as “old white guys”.

Engineering is a discipline that requires experience and guidance. The young learn from the old. In this case accomplished engineers missed a chance to do rewarding work with young engineers and young engineers have to live with the guilt of killing their crew.

This is a lesson the entire tech industry would do well to meditate on. Especially when we call ourselves engineers.

Immediate implosion if a far more likely explanation because give that we knew it imploded the most likely time would be immediately after the pressure vessel reached maximum or near maximum stress and it failed. The time actually is not the biggest factor; it is the number of cycles the pressure vessel has endured. An implosion after a relatively low number of cycles is consistent with past incidents with pressuriza…

The most puzzling aspect, from what I understand from the experts, if it imploded at time and depth you are suggesting it would have been very likely to be registered by at least the controlling ship due to the noise. As you highlighted the sub is pretty large, imploding in a millisecond causes huge effects in the surroundings. So saying it got lost and imploded after a few days solves two problems. Explains why ther…

There’s a series of episodes of Smarter Everyday where the host goes on a US nuclear submarine and interviews the crew and shows some of the equipment. In one of the episodes, they talk to navigators, who explain that submarines can be invisible to sensors in certain locations because the ocean water is not uniform. Temperature, currents and salinity vary, so a sound could be attenuated in some directions.
