Quoted: 'I went on Titan - it was a SUICIDE mission!' German who paid OceanGate to see Titanic wreck in 2021 says he was 'incredibly lucky' to make it after one sub 'didn't work', there were 'electrical problems' and piece of the vessel FELL OFF https://i.dailymail.co.uk/1s/2023/06/21/10/72366181-0-image-a-11_1687341514264.jpg Arthur Loibl (top left), 60, dove the 12,500 feet to the Atlantic ocean wreck site in August 2021, and says he was 'incredibly lucky' to survive. His story echos much that has been learned about the OceanGate tourist vessel since it vanished into the abyss on Sunday, with past reports highlighting how many components were purchased off-the-shelf. It has also been revealed to have been uncertified to dive to the necessary depths to reach the famous Titanic wreckage. A German adventurer who paid to see the wreck of the Titanic on the missing Titan submarine two years ago has called the voyage a 'suicide mission'. Arthur Loibl, 60, dived down 12,500 feet to the Atlantic wreck site in August 2021 and says he was 'incredibly lucky' to survive. His story echos much that has been learned about the OceanGate tourist vessel since it vanished on Sunday, with past reports highlighting how many components were purchased off-the-shelf. It has also been revealed to have been uncertified to dive to the necessary depths to reach the Titanic. Speaking to German tabloid Bild, Loibl recalls the first submarine they tried didn't work and a second attempted dive had to be abandoned. He said parts fell off and the mission went into the water five hours late due to electrical problems. This, Loibl suspects, could be the cause of the Titan's disappearance. https://i.dailymail.co.uk/1s/2023/06/21/13/72365523-12218125-German_explorer_Arthur_Loibl_right_60_dove_the_12_500_feet_to_th-a-1_1687351742553.jpg https://i.dailymail.co.uk/1s/2023/06/21/13/72365521-12218125-Speaking_to_German_tabloid_Bild_Loibl_pictured_recalls_that_the_-a-2_1687351742554.jpg Speaking to German tabloid Bild, Loibl (pictured in front of the OceanGate sub) recalls that the first submarine they tried didn't work, that a second attempted dive had to be abandoned, parts fell off, and that his mission went into the water five hours late due to electrical problems 'It was a suicide mission back then!' Loibl tells Bild. The German knows a thing or two about risk taking, too. He has previously travelled to the north and south pole, and flown over Russia in a MiG-29 fighter jet. But out of all his adventures, 'the Titanic was the most extreme,' he says. He paid 100,000 euros and booked the trip through an English company that organises special safaris, Bild reports. He says the start of the expedition was bumpy. 'The first submarine didn't work, then a dive at 1,600 meters had to be abandoned. My mission was the 5th, but we also went into the water five hours late due to electrical problems,' he recounts to the publication. Shortly before the sub was launched, Loibl says the bracket of the stabilization tube - used to provide balance as the craft descends into the depths - fell off the vessel. 'That was reattached with zip ties. That did worry me,' he tells Bild. As for conditions inside the vessel, the adventurer says they were challenging. On his voyage, he was joined by French explorer Paul-Henry Nargeolet, 73, and OceanGate's CEO and pilot Stockton Rush, 61. Both are currently on the Titan and have been missing since Sunday, along with British adventurer Hamish Harding and Pakistani nationals Shahzada Dawood and his son Suleman. Up to five passengers can be taken on the 22-foot long Titan. There are no seats, a single toilet (with a black curtain pulled across for 'privacy'). At a depth of around 3,200 feet, sunlight can no longer penetrate the darkness of the ocean. 'You need strong nerves, you mustn't be claustrophobic and you have to be able to sit cross-legged for ten hours,' Loibl says. 'It must be hell down there. There's only 2.50 meters of space, it's four degrees, there's no chair, no toilet.' When he did reach the Titanic, however, he described a sense of euphoria. With Loibl inside, the Titan travelled around the wreck twice and once even touched down on its deck, he said, before making the return journey. The German said he is closely following the news of the missing submersible and the search operation - which is rapidly running out of time. 'I feel bad, I'm nervous, I have a sinking feeling in my stomach. I was incredibly lucky back then,' he told Bild. Like many, he is hoping for a miracle. For his next adventure, Loibl said he had hoped to fly into space with Virgin Galactic for $250,000. But after the 'drama' surrounding the missing Titan vessel, he said, 'my whole pursuit of extremes is now in question'. https://i.dailymail.co.uk/1s/2023/06/21/17/72381871-12218125-image-a-24_1687366165642.jpg Continued View Quote Fuckin’ mint, eh? |

Quoted: Stop thinking like a 50 year old white guy. View Quote View All Quotes View All Quotes Quoted: Quoted: A question for those who know something about carbon fiber structures, because I don't. I thought (could be wrong) that carbon fiber is very strong in tension but not so good in compression. Therefore with a pressure vessel, a carbon fiber construction would be good if you were going to put 5-6000psi inside the container. That way the container is trying to expand, like a balloon, and carbon fibers are in tension and that's where they are strong and the container works. But with this sub the carbon fibers are being compressed by water forces around the outside. If carbon fiber is weak in compression isn't this whole design wrong? . Coincidentally I may resemble that remark … |

Quoted: Do they actually have sonar and submersibles in the area looking at this point (Wed afternoon)? They have not even located the sub yet, starting to get hard to believe that there is any hope. Even if they located the sub right now would they have time to get down to it. It would have to be an incredibly easy rescue like just cut a hung cable. View Quote There might be an unmanned submersible in the water now. |

Quoted: Most amazing thing out of all of this for me, is learning how a plane that is noisy as fuck can “hear” banging underwater View Quote Sonobuoys are an amazing thing, and definitely a case of "Your tax dollars at work." The P-3/P-8 guys are very good at what they do. However, they're usually dealing with a target that, max (and that's pushing it, with an Alfa, Sierra, or Mike before it went Boom!) that's 1/3 the depth of the search space this sub could be in. Sound bends in water. A lot. Depending on what layers the sound is going through, this sub's position fix could be like the bowfisherman's aiming problem on steroids. |
|
Quoted: Initially..Did the banging noise move ? Or continue from the same location ? If the sub is at the wreck site or within 1K feet then they can see it on sonar and would have found it on sonar within the first few passes. They would already have confirmed they are on the wreck site by now. The fact ships are banging away with sonar miles away suggests they already know the sub is not at the wreck site. View Quote Would they spot it (or really notice it) on the bottom? It’s not very big and there is a large pre-existing debris field - that may be well mapped, but once a candidate spot is found, then wouldn’t they need to send an ROV to investigate? If so you need to be lucky on the first shot due to the clock getting near the end for O2. I wouldn’t think moving a little ROV around that maybe goes a couple MPH/knots at several possible hits will go quick But the families have to hold onto some hope which is why they probably haven’t said it’s really just a recovery, or really locating the site and leave it to be, the sea claims it’s own if it’s even intact |

I don't have experience with the G710 specifically, but I DO have a G310 and was looking hard at the G710 for a Retropie setup. I ended up cheaping out and bought a second-hand PS3 Sixaxis. The G710 has a solid reputation and wasn't the ONLY method of controlling the sub's movement. I would never use a piece of gear for something critical that was not 100% effective or reliable. You DO realize it's not "critical", right? It's probably better than a touchscreen for making fine adjustments, but the failure of the gamepad is way down the list of things that likely put them in the position they're in. And if it cost $300, he's 10 times smarter, right? What are you babbling about? |

Quoted: Why are we wasting $$$ and resources on some billionaire’s private enterprise failure? Inquiring minds want to know. View Quote Practice. A lot of the techniques and processes that are being used now, have utility for salvage or even rescue of other stranded submersibles. Plus, it's a human thing to do. Law of the sea and all that.

For those who want to actually think about possiblities...
To raise the sub if they find it and can get a remote control sub to it: There are photos online of the sub being lifted using two straps wrapped around the tube/end cap mating surfaces. In other words they do not have lifting eyes on the sub to lift it. A remote control sub is not going to have the capability to wrap a strap around the sub while it is laying on the sea floor. There appears to be no available structural points to lift the sub that are accessible with the shrouding in place(and there may not be any lift points underneath the shroud). So any lifting is going to be very risky and, if the people are alive, very dangerous. If the sub is floating on the surface is weighs in excess of 23k pounds, so the only helicopters that could even maybe lift it would be a ch53 of a ch47. Getting a strap around the floating sub is feasible, but also risky(if it is dropped the people could easily be killed when it hits the water). In other words, if they do find it floating they will have to wait for a surface ship to catch up to it. |
