Tourist submarine goes missing on dive to wreck of Titanic
- leobg 3y agoService Unavailable is what I get when I visit their website. [1] Probably true. [1] https://oceangateexpeditions.com/titanic https://oceangateexpeditions.com/titanic

- wiskinator 3y agoIt's weird that I'm just finding out that there's a company that does this when their business goes sideways. Kinda also wondering if I can scrape 250,000$ together...
- dehrmann 3y agoThere's at least one company that does rides in fighters. Seems a little safer.

- OneLeggedCat 3y agoWell that's awesome. "You’ll get a thrilling approx. 45-50 minutes jet ride including: - A walk around the MiG-29 jet including detailed explanations - Cruising at double Supersonic Speed (Mach 2) - Manoeuvres such as rolls, steep diving and climbing and more, depending on what your worked out plan together with the pilot - A fantastic view onto the earth from above - You will see the curvature of the earth - Possibility to control the jet" "45-50 minutes MiG-29 flight costs EUR 17,500" That's almost affordable. If my wife ever leaves me, I'm doing this.
- api 3y agoSince you can see the curvature of the earth you can also prove it’s round. Big bonus.
- Arch485 3y agoMaybe the article just excluded this detail, but is there any reason for a submersible to not have a black box and transponder similar to an aircraft? Do they not work under water after a certain depth? I feel like the company in charge of all this should at least know where the submersible is, if not what happened to it.
- s1artibartfast 3y agoBlack boxes don't give real time updates above or below water
- EA-3167 3y agoThere are technical limitations there, the only really viable way to signal from great depths would be sonar. A radio beacon would be useless under 4000m+ of water, and there's no realistic way to ensure that a small bit of wreckage ever surfaces to make a radio beacon work. There's also no legal requirement, there is no FAA for submersibles. Now something like an airplane's black box has an underwater locator that works for a while, but there's no particular reason to expect that a meaningful and timely search can be made at the sort of depths a submarine like the one in the article works at. tl;dr Rescue and recovery at 4000m+ is pretty much never going to happen, although it is technically possible, and there's no reason to worry about safety standards for something this niche, or limited to militaries.
- Rebelgecko 3y agoRadio waves don't work well through salt water. Even VLF signals have trouble going past like 30 meters. There's some super duper low frequency radios but it's still a one-way proposition - build a huge facility on land to communicate with subs, and if the sub needs to reply it has to surface. And even that limited setup is only doable by the military industrial complex of a small handful of nations.
- phire 3y agoBit of an understatement. ELF (Extremely low frequency) requires finding a section of earth's crust with very low conductivity that can be repurposed as an antenna. These antennas are very large, the US had one that was 45km long, the Soviet antenna is 60km long. The resulting signal has a wavelength of 3500-4500 KM, about a quarter of the earth's diameter. Because of this huge wavelength, the bandwidth is extremely low. The US system took 15 minutes to transmit a single 3 letter message. The system was only really useful for transmitting pre-agreed signals (which were usually along the lines of "surface and contact us for the actual orders"). But they also acted as a dead-mans switch, they continually transmitted an idle signal. If they stopped transmitting (which would still take several minutes to notice) subs would establish communication to check if a nuclear war had started.

- PM_me_your_math 3y agoThey are likely lost forever. Even a pinhole at depth puts enough pressure into the cabin to liquify everyone inside moments before the external pressure crushes the vessel like an empty can of soda. Assuming it was not a loss of pressurization or hull related failure - say it was electrical or mechanical, it is very cold i̶n̶ s̶p̶a̶c̶e̶ on the ocean floor.

- j-pb 3y agoAlthough I feel bad for everybody involved, making billions selling the most polluting transport system on the planet (private jets) and then getting crushed by the ocean certainly feels like karma.
