Without confirmation of location, you are likely past the point of any recovery by an ROV finding them and somehow assisting with surfacing. If they have surfaced, then you have until the O2 runs out, which is late tonight / early tomorrow AM.BenFiasco14 said:

They weren't using that though. They were using a Logitech controller (third party)
Quote:
The controller - which runs on two AA batteries - has a 4.2 out of five overall score on Amazon, but hundreds of one-star reviews dating back more than a decade claim the device suffers from irritating and regular connection problems.
Other themes among the negative reviews include problems with the controller's analog sticks and that pressing certain buttons scrambled the entire pad.
And the Logitech G F710 Wireless Gamepad is only compatible with decade-old Windows and Chrome systems.

I'll be very callous about this but why are we spending so much taxpayer money to try and find them? I told my daughter if it was a fishing charter or something routine then that is why the CG exists. This is an extreme adventure that went wrong. Another analogy would be snow skiing (normal) at say Breckenridge versus climbing Mount Everest. One has low risk and the other is extreme.

There was some underwater noise heard. Could be a million different things. Any reports that it was every 30 minutes or somehow confirmed to be Titan are not accurate

It's not made it once. This was the first try. The previous "test" only went down to 3000m with only the CEO. So they have never tested the hull integrity beyond 3000m and the Titanic wreck is beyond that.

Not sure how many granola bars and lunchables they packed, but I imagine if they have survived this long they are in dehydration and getting pretty hungry.

Yeah, I haven't seen anywhere that they've gotten a confirmed ping since early Sunday morning.

That would be huge news. Everything I've seen is no official ping since it got lost a few days ago, with its last position at the last ping just above the titanic. And the underwater noises lead has also turned into a dud

That is probably for the mother ship only. Stupid journalists don't ever try to explain things properly.
It's been all the way down to Titanic a few times, plus several other unsuccessful attempts. In fact, that's the concern, the repeated strain on the hull. I don't know why anyone would say it's the first try for this particular craft.eric76 said:Wouldn't it make sense to send it, unmanned, to deeper depths than the lowest manned depth it would ever need to handle?Mathguy64 said:BadMoonRisin said:

I just don't understand why someone would want to pay $250k and risk their life in one of the most inhospitable places on the planet to view an old shipwreck. I have watched all of the videos of the wreckage on YouTube that all of the different expeditions have shot and I am perfectly fine leaving it at that. There really isn't much to look at other than a big blob of wreckage covered in coral and slime. They can only look out the one small window and most likely can only see ten feet in front of the window clearly anyway. Whatis the lure for this? To be able to say you are one of only a hundred or so people to be down there?
It would be nice to have a proven safety margin. I don't think that having gone to the same depth twice before tells you much at all about the safety margin.Joes said:It's been all the way down to Titanic a few times, plus several other unsuccessful attempts.

The Titan has visited the Titanic wreck site three times, the first of which was in July 2021

Don't forget the selfie factor. A lot of society can no longer enjoy life, their kids, an event or even seeing the titanic without the utter bliss of snapping a shot of themselves.
At this point, I hope they went quick and before they knew what was happening. That CEO otoh deserved so much worse for influencing people into something this stupid and unsafe. This is like convincing people to jump a motorbike over an active volcano. Just because you're a cavalier rich guy toying with death, there's no reason to try to enlist tourists as well.
There's a reason planes and boats aren't piloted with these things though. A few very typical specs for electronic operating conditions:fka ftc said:

iXblue INS, USBL Chosen
For Titanic Expedition
OceanGate Inc. and iXblue are combining forces to conduct the first manned submersible expedition to the wreck of the RMS Titanic since 2005. iXblue's Phins 6000 inertial navigation system and Posidonia USBL positioning system will be used for the accurate and reliable navigation and positioning of OceanGate's Titan, the newest addition to the company's fleet of deep-sea manned submersibles and the first privately owned manned submersible capable of reaching Titanic depths.
iXblue's strap-down fiber-optic gyroscope (FOG) technology, Phins 6000 subsea inertial navigation system (INS), provides accurate position, heading, attitude, speed and depth information as the manned submersible captures laser data and the first-ever 4K images of the RMS Titanic shipwreck and debris fields. Its high-accuracy inertial measurement unit is coupled with an embedded digital signal processor that runs an advanced Kalman filter for optimum positioning of the subsea vehicle.
Increased positioning precision of Titan on the shipwreck site will be provided by Posidonia, iXblue's long-range, high-accuracy USBL system operated from the surface ship and calibrated thanks to a Phins surface INS. Designed to track subsea vehicles to depths of 6,000 m at ranges reaching more than 10,000 m, Posidonia uses advanced acoustic modulation and digital signal processing technology and operates in the low frequency band for deep-sea tracking operations. To communicate with Posidonia, Titan is equipped with iXblue's MT8 compact low-frequency transponder.

Underwater modems
In April 2017, NATO's Centre for Maritime Research and Experimentation announced[12] the approval of JANUS, a standardized protocol to transmit digital information underwater using acoustic sound (as modems with acoustic couplers did in order to make use of analog telephone lines).[13] Documented in STANAG 4748, it uses 900 Hz to 60 kHz frequencies at distances of up to 28 kilometres (17 mi).[14][15] It is available for use with military and civilian, NATO and non-NATO devices; it was named after the Roman god of gateways, openings, etc.
Do you have a link for this? I haven't seen this to be accurate anywhere. I know the sub pinged right before it lost communication, but everything I've seen since says the current noises are simply some type of banging.agracer said:
