@antipodean Yeah, obviously pressure/depth changes things somewhat.
But given they can hear the sounds of banging (assuming they come from the sub), then that would suggest that Sonar is still capable.
It's probably fair enough to assume Physicists know better than me, though. Be nice to here a laymans explanation.
No, it is nowhere near as simple. Esp 4k down. I have done my time in ASW helicopters and sound tracking is bloody complex. You can scan to that depth, with specialised gear. It does a very narrow so and the resolution is not great. If it was easy every single wreck full of gold in the world would've been found by now

@Victor-Meldrew it did occur to me that this is getting a helluva lot of coverage for 5 people no-one knew until now.
it presses all the media buttons
Titanic
A ticking clock
Deep sea expeditions
BillionairesI can't get excited, but it is right up main stream media channels. THe sub sounds like a non-certified death trap.
It had lights bought from a camping store, and the steering was a gaming controller! That's intrepid
Game controllers are used in a lot of real world places. Military use heaps, why reinvent the wheel, cheap, reliable and easy to have spares

Yes the game controller thing is a bit silly considering they're apparently also used on nuclear subs. I'd say that was the very least of this vessel's problems.
You couldn't pay me enough to get in that thing. The idea that people paid stupid money to get in it blows my mind. But I guess when you can buy anything, you think differently. Still...look at that thing!

I think the "US$30 game controller" aspect just looks symbolic of their approach to many aspects of sub design, build, materials, & operations.
Team NZ used one as well I think, for sail trimming. They are pretty awesome pieces of kit for the price - just the optics are poor

The word "missing" always felt exceptionally hopeful.
'Entire week has been prolonged and nightmarish charade' - Director James Cameron
Director James Cameron, who has completed 33 dives to the Titanic, has told BBC News that he predicted this deadly outcome days earlier.
The director of the blockbuster film Titanic said he was on a ship on Sunday when the sub first went missing, and he did not hear about its disappearance until Monday.
When he learned that the sub had lost both its navigation and communication at the same time, he said he immediately suspected a disaster had taken place.
"I felt in my bones what had happened. For the sub’s electronics to fail and its communication system to fail, and its tracking transponder to fail simultaneously - sub's gone."
Cameron told BBC News the past week has "felt like a prolonged and nightmarish charade where people are running around talking about banging noises and talking about oxygen and all this other stuff".
"I knew that sub was sitting exactly underneath its last known depth and position. That's exactly where they found it," he continued.
He added that once a remotely controlled underwater vehicle was deployed on Thursday, searchers "found it within hours, probably within minutes".

A good listen. And Bob Ballard makes the point, gently, that this is the first of any of these types of subs to be lost since deep sea ops began in the the 1960's. Looks like he's still a very busy man for an 80 year old.
Part two: adding Cameon's follow on interview as the other one to have 'been there, done that', and gets into the technicalities and safety concerns.

@Donsteppa from The Australian:
A top secret military acoustic detection system designed to spot enemy submarines first heard what the US Navy suspected was the Titan submersible implosion hours after the vehicle began its mission, officials involved in the search have revealed.
The Navy began listening for the Titan almost as soon as the sub lost communications, a US defence official told the Wall St Journal. Shortly after the submersible’s disappearance on Sunday, the US system detected what it suspected was the sound of an implosion near the debris site and reported its findings to the commander on site, defence officials told the newspaper
“The US Navy conducted an analysis of acoustic data and detected an anomaly consistent with an implosion or explosion in the general vicinity of where the Titan submersible was operating when communications were lost,” a senior US Navy official said in a statement. “While not definitive, this information was immediately shared with the Incident Commander to assist with the ongoing search and rescue mission.”

when communications were lost
I undrestand
- the only comms was a cellphone onboard to text message
- the hatch can only be opened from the OUTSIDE
amongst many other non-safety features, like no ability to drop ballast, no blow tanks, etc.
/shakes head.

@nzzp said in Titanic tourist submarine:

takes like 2 hours or something to unbolt/seal it!

Sounds like the last comms may have been that they were trying to resurface.
Allegedly, the safety mechanism built in for the composite fibre hull was not some appropriate/stringent form of design and stress testing or similar, but some sort of monitoring and alarm system to announce that it was starting to delaminate.
If so... rather than careful and preventative design, just an alarm to announce you're about to have an extremely bad day.
Journalist David Pogue, who rode in Titan to view the Titanic in 2022, noted that Titan was not equipped with an emergency locator beacon; during his expedition, the surface support vessel lost track of the Titan "for about five hours, and adding such a beacon was discussed. They could still send short texts to the sub, but did not know where it was. It was quiet and very tense, and they shut off the ship's internet to keep us from tweeting."

I shouldn't laugh, but...
Amazon has begun moderating the reviews section of the now infamous games controller used to control the missing Titan sub.
As news of the missing sub spread earlier this week, bad taste reviews began to appear on the shopping giant’s page for the Logitech F710 controller.
Users posted about the controller "not being good at steering a submarine" and "losing signal in the ocean".
Before the fate of the crew aboard the sub became clear, the posts received hundreds of approvals from other shoppers and some were made into viral TikTok videos.
Amazon has started deleting the reviews as it’s understood they do not comply with community guidelines.
The Logitech F710 controller is a popular games console accessory which wirelessly connects to gaming consoles and PCs.
The relatively cheap £33 ($42) controller has become a focal point of the technology on the Titan since videos of the company CEO using it were posted online

LOL what 'bodies'? In the fast jet world, we are told to tell our partners not to ask for anything like your wedding ring if you pile in. Sandbags in the coffin time, your body is nothing bit tiny bits of matter and everything else is crushed and mangled
