The hatch is bolted shut from the outside. When you make it back to the surface, there is no way to get out without external support.
If the mother ship can not find the sub the occupants could be trapped bobbing just below the surface until their air runs out.
- paulpauper 3y agoit should be findable by simple radio/celular contact?
- accurrent 3y agoThis is under water. Radio/Cell do not penetrate beyond a few centimeters. Communicating underwater is usually done via acoustics.
- paulpauper 3y agobut the op said "If the mother ship can not find the sub the occupants could be trapped bobbing just below the surface until their air runs out." just beneath the surface
- bob778 3y agoIn submersible tech, just beneath the surface is 0-30m depth basically (for salt water). Cellphones signals are about 2m max while higher frequencies (eg 2.4GHz) drop off exponentially so are <1m
- omniglottal 3y agoAntennea can trivially extend over 30m, and can float on the surface. As a wire attached to an inflatable float, for either bidirectional communication or as a GPS beacon, or both, the complete solution could exist for less than $10k and less than 10 kilograms to solve this. Why doesn't this exist for this craft that can only be openned from the outside?? There exists the ability to communicate from directly above, so why can't it also communicate (further) through open air while bobbing near the surface?
- themoonisachees 3y agoYou seem to be under the impression that the people paying a quarter million dollars to get bolted shut in an experimental sub to go see the titanic are reasonable and people who would think of that. They aren't.

- venusenvy47 3y agoThey have some type of radio link that works at depth for simple texts messages, but they have to be right above it.
- mcpackieh 3y agoThat doesn't seem right, do you have any source? VLF wouldn't stand a chance of reaching that deep and ELF requires extremely large antenna to work. More likely they were using some form of underwater acoustic communication, sending and receiving data through sound instead of radio waves.
- venusenvy47 3y agoI don't have information about the type of communication link. I shouldn't have called it a radio link. Acoustic probably makes more sense. It was something very slow, so that sounds right.
- jliptzin 3y agoSeems like a pretty stupid design if you ask me
- gmiller123456 3y agoThat's what Gus Grissom said.
- justrealist 3y agoLot of people probably won't get the subtext on this one. (although he was recently-probably-exonerated in that case).
- jonathankoren 3y agoI think it’s more the Apollo 1 door opening to the inside and secured by nonexplosive bolts, rather than the spuriously blown door on Liberty Bell 7. FWIW, while NASA may had thrown him under the bus, his comrades in the astronaut corps believed him. Wally Schirra on Sigma 7, refused to blow the door until the capsule was on the Kearsarge. When he climbed out, he showed the bruise on his hand — the same bruise every one got when they pushed the escape button. The same bruise Grissom did not have. https://www.npr.org/2021/07/22/1019254674/gus-grissom-liberty-bell-mercury-the-right-stuff https://www.npr.org/2021/07/22/1019254674/gus-grissom-libert...
- sclarisse 3y agoIt’s pretty bad, but when the door accessible from the inside implodes from the insane pressure of the water around it, that’s even worse.
- fergbrain 3y agoThe door can still be designed to open outward and also able to be unlatched from the inside: those aren’t mutually exclusive properties.

- crabmusket 3y agoThat's the most horrifying detail of the whole affair, to me.
- dheera 3y agoCould they just have some drills with diamond-tipped bits stored inside for emergency use? If needed, drill through the whole shell, stick an arm out and unbolt from the outside. Or maybe a jackhammer to just hammer through whatever glass is there for observation purposes.
- Vecr 3y agoI don't think there is any glass. Both of the end caps are supposedly titanium and there are cameras.
- ralusek 3y agoAt that point just watch a video, or drive an unmanned submersible.
- Vecr 3y agoI think the point is to reduce cost and speed up operations by not having a tether. You can't do wireless video under thousands of feet of salt water. The options are AI or humans. There is a podcast and a news video linked here on HN.
- disillusioned 3y agoThat's not true. There is a "large viewport", per their website: https://oceangate.com/gallery/gallery-titan.html https://oceangate.com/gallery/gallery-titan.html

- SketchySeaBeast 3y ago> Or maybe a jackhammer to just hammer through whatever glass is there for observation purposes. I'm now wondering if a jackhammer applies more force than the ocean at titanic depths. I suppose less uniform force at least.
- carbine 3y agoAccording to David Pogue (journo who did a dive on this vessel last year), at least as of last year there was no beacon to transmit location. One would hope radio would be working, in that case. Source: https://twitter.com/Pogue/status/1670826522138091521?s=20 https://twitter.com/Pogue/status/1670826522138091521?s=20
- boppo1 3y ago>sealed from the outside >no location beacon Wtf is anyone thinking getting in this thing?
- koolba 3y agoThe set of people that would enter an experimental sub to visit the titanic, and the ones that would do it with a craft that is bolted shut from the outside, is probably close to even.
- themoonisachees 3y agoAdd to that the $250000 price tag qualifier
- venusenvy47 3y agoAnd literally steered with a cheap game controller. There's a YouTube video from CBS of their reporter taking a trip on this thing. It's almost comical how cheap it seems.
- justsid 3y agoWhat’s wrong with game controllers? They are built to be ergonomic and in use for extended periods of time. Also a lot of people are already familiar with how to use them. Not saying we should replace every bespoke interface with a game controller, but using a game controller isn’t necessarily bad either.
