They are activated automatically (float off) or manually (turned on). Float off is obviously not an option. How do you turn one on and send it to the surface (never mind it won’t survive the pressure) when you can’t open the only entrance/exit?

Are you kidding? The toilet alone nearly broke their budget!

Damn this thread is moving fast.

Did they find the foundering vessel and rescue all souls on board and reunite them with their families and pets on the deck of the mystery rescue ship with back slaps and tears and tugging at your heart stings music or something ?

Scba off a fire engine, sure your supposed to get 15 min of air, go fight a real fire and have a dozen curve balls thrown at you in the situation and you will feel like it lasts 5 min

Most people in that situation will panic, probably a lot of fighting as well over the situation

Then again, do we trust anything from this company? They probably claim 5 days knowing it has 2 and “nothing will happen” anyways mentality

Conduit with weep holes.  Protect the cabling but allow the pressure to equalize.

Just going to say this. All the ones we picked up were red and did not look like they died a happy death.

Its been answered several times, your question even has the answer in it: Thats 50 year old white guy thinking. Ocean Gate knows that their strength comes not from their engineering, nor their rhino liner coated, carbon fiber hulls, but from their inspirational diversity, a strength even the deepest depths can never overcome.

Did Vossler fix the comms problem ?

Nice choice for a company name. Oceangate. Let that sink in.

I remember going to bed knowing Trump won only to wake up and they found votes for Biden.

Going to bed unhopeful. Hoping for a full reverse course when I wake up.

Ha!
I was thinking the same thing...

I would also point out that those sonobuoys do have a finite shelf life.  They are designed to corrode/dissolve away over time.  The batteries in them are (at least from what I remember) packs made of alkaline batteries.

Better used for this than sit in storage and expire only to be trashed/demil.

It’s actually ELF (extremely low frequencies).  The sub raises a cable on a buoy to around 30 meters for comms.
I guess no Netflix on the boomers.

It would probably happen so fast, they're nervous system wouldn't even register it.

Like swatting a fly.

No Nikes.

Wife of missing OceanGate CEO is the great-great-granddaughter of Macy's founder and his spouse who were immortalized in James Cameron's Titanic movie as elderly couple who embraced on the bed as the 'unsinkable' ship went down



Wendy Rush is the wife of OceanGate CEO Stockton Rush, who is among the five people missing on board the submersible. Her great-great-grandparents died on the Titanic




Isidor Straus and his wife Ida died on the Titanic. Isidor co-owned Macy's with his brother, Nathan: their father, Lazarus Straus, convinced Rowland Hussey Macy, founder of Macy's, to allow L. Straus & Sons to open a crockery department in the store. Isidor and Nathan became co-owners in 1896




Isidor and Ida Straus are depicted lying on a bed as the water rises in the 1997 film



The pair had in real life been offered seats on a lifeboat - her as a woman, and him as a well-known former congressman and co-owner of Macy's department store. But Isidor refused, saying he would not go until all the women and children had gone, and Ida then refused to go without her husband of 40 years.

She gave her mink coat to her maid, Ellen Bird, to keep her warm as she sailed away on the lifeboat.

Wendy Rush, born Wendy Hollings Weil, married engineer and entrepreneur Stockton Rush in 1986.

She is descended from Isidor and Ida Straus's daughter Minnie, who married Dr. Richard Weil in 1905.

Their son, Richard Weil Jr., later served as president of Macy's New York, and his son, Dr. Richard Weil III, is Wendy Rush's father, The New York Times reported.

Wendy Rush has visited the Titanic wreckage three times with her husband's company in the last two years, and works as OceanGate's communications director.

Stockton Rush, 61, founded OceanGate in 2009.

The Seattle-born, Princeton-educated aeronautical engineer worked on fighter jets and initially hoped to go to Mars before switching his attention to the sea.

I wonder how much time the CEO had to ponder whatever situation he was in could have been avoided by not cutting one of the many corners he cut.

I'm sure even as he's suffocating his final thought will be "fuck those white guys"

They're always stubborn to the end.

Updated—UHF and most radio signals are worthless under seawater.  EPIRBs and Personal Locater Beacons are worthless underwater.

These are knock offs of the original that is a very good switch. I forget the brand of the good ones, been a while since I used them, but they are very nice switches. That said, no idea what they used here.

Stick to HVAC. ELF has long been decommissioned. VLF is still in use.

I remember that book.

Moral of the story for seafarers:  Don't name your shit anything with "Titan" in it and sail it into the Atlantic.

I wonder if the Titanic was an attempt at being semantic about it?  "Bruh!  Why did you name that ship TITANIC?!?"

"Dude, it's ok.  We add the "ic" so it's fine."

if they by some miracle find it how do they bring it up?

His turned red and green. I've only seen that in the Amazon flavor. In the video it looked like it flipped the relay for one bus .

So's the Titan.

At this point, unless they're very lucky, they probably don't. At least not in time.

I grew up using basic

10 goto 20 if x>y.

They're dead Jim.

Exactly. People complaining about the cost and actually using equipment...this is getting the right people valuable experience and making sure systems work as intended which you can't replicate fully with training.

Well its been fun following this thread.

Honestly its been educational.

However it seems that its come to an end, unless the finger of God happens to intervene between now and tomorrow morning.

I'll pray that He does and hope that it's His will.

Apropos of that, they're reforming the company as Watergate...

I beg your pardon for the misinformation. I do have 2 Ham licenses.  The licensing study books had very little on Sub comms.
Please enlighten us.

Explorers Club president says life-saving deep sea surveillance drones for Titanic sub search are being caught up in red tape by the Coast Guard and GOP Rep. Dan Crenshaw demands answers


Richard Garriott, president of the New York-based Explorers Club, on Wednesday said vital rescue equipment was being held up by US bureaucracy


The president of the New York-based Explorers Club has accused the U.S. government of delaying the delivery of vital equipment for the search for the missing Titanic tourist sub.

Richard Garriott told National Geographic that he had complained to top officials about the bureaucracy hampering the race against the clock.

Two of the five on board - British billionaire Hamish Harding and French Titanic expert PH Nargeolet - are members of the Explorers Club.



Other members have worked to enable deep sea company Magellan, based in Guernsey in the British Isles, to ship its surveillance equipment to the site: Magellan has Remotely Operated Vehicles (ROVs) which last year surveyed the Titanic site.

Yet Magellan has not obtained the permits necessary to get to the site, Garriott said.

He wrote on Wednesday afternoon to Vice Admiral William Galanis, commander of Naval Sea Systems Command; U.S. Coast Guard Rear Admiral John W. Mauger, who is leading the recovery mission; Congressman Lloyd Doggett; and Representative Eric Swalwell, urging them to allow Magellan to the site.

'Magellan has received mixed signals, first hearing from US Gov to get ready, waiting for plans - then getting told to stand down,' wrote Garriott.

The U.S. Coast Guard has not responded to DailyMail.com's request for comment.

Garriott told National Geographic that, even with only 24 hours of air left, it was vital to continue fighting to find the missing sub.

'Whatever the right thing is to do, we should still do it, even if it's now at the cusp of fatality,' he said.




The Magellan Argus-class ROVs are capable of deploying to 6,000 meters (19,700 feet) and are outfitted with external arms that can retrieve and raise Titan.

They could be delivered to the site within 16 hours.

Instead of Magellan's ROVs, the U.S. Navy has sent its Flyaway Deep Ocean Salvage System, which was used to retrieve an F-35 from 12,400 feet of water in March.

But Garriott said that there are fears the Navy's equipment will crush the capsule.

'The concern is that the big scooper will crush the hull, because it would be almost impossible to get down under it in the mud without applying pressure to the hull itself,' said Garriott.

'Instead, a 6,000-meter working-class ROV has the ability to attach directly to the point on the top of the sub.

'It's a traditional method and people like Magellan have done it over and over again. It's the way it's designed to happen.'

Garriott's concerns about the bureaucratic hurdles echo those aired on Monday by OceanGate advisor David Concannon.

'We need to move. We do not have minutes or hours. We need to move now,' he said.

'This equipment has been on the tarmac for hours.

'When I communicate with the U.S. government, I get 'out of office' replies - not from everyone, but from key people that have a sign-off on this.'

He told NewsNation: 'That's unacceptable.'

Their branding is on point for notoriety.

Heaven’s

The new company will be run by a bunch of white dudes in their 50s. They might rename it Whitewater.

What do they broadcast out of Jim Creek?

52 year old checking in on likely page 54,

I have no HAM licenses. Look at my screen name and avatar. What do you think I’ve done for the last 40 years?

Lord British should stay in his lane

Is that this one?

Weve been off 54 over 3 hours.

So, possibly as long as this original dive lasted before they died.

I’d like ham on my sub, to eat while listening to a stereo with an awesome subwoofer.

Also, thanks for your insight & explanations. I always look for your posts in these discussions.

LF/VLF though the freq escapes me. I was an east coast sailor.

There are a multitude of Switches like that, i new exactly what you mean. They are use for industrial applications, especially in food and pharma industry.

But they might have used these : https://newwiremarine.com/push-button-switches/bluewater-switches/bluewater-22mm-stainless-combos/

For a submersible like that to communicate with the surface over long distances you're looking at acoustic waves, not radio or light. There are commercial systems which can do it. I think that might have been what the "texting" mechanism was that they were using with the surface.

Not enough failsafes here. There should have been some sort of acoustic beacon on a timer strapped to the outside of the damn sub, set to start beeping after 8 hours on a periodic schedule to conserve power.
