Yeah at this point, it seems that catastrophe struck 90 mins or so into the dive. That is when contact was lost.
They were early enough into the dive that they would have abandoned the dive after losing contact, they would have only been about halfway to the bottom, and they still would need communication to even find the titanic. So if they lost contact, the mission would have been aborted inside the sub, because they wouldn't have any hope of completing the mission without the aid of the surface vessel.
There are several emergency surfacing options available on the sub in addition to the primary propulsion method. If the sub lost contact, it would have surfaced. That is what happened in several other missions this company has made where communication was lost.
So the fact that communication was lost and no attempt to surface was made, suggests that there was a catastrophic failure. At the pressure they were at, the smallest leak would lead to immediate implosion. The most likely scenario is that they experienced a crack or defect in the hull that lead to implosion. It was likely over before anyone onboard even was aware of a problem (or within seconds of it).
- avidphantasm 3y agoWhat “mission”? There’s no mission here. These were people with more money than sense going sightseeing where they have no business being.
- greiskul 3y agoMission is a perfectly valid word for describing an outing of a submarine, specially when most of the discussion is surrounding the technical aspects of it. Do you also get angry when a business describes something as mission critical?
- avidphantasm 3y ago> Do you also get angry when a business describes something as mission critical? Not if they are doing something useful to others. Are hikers who get lost on a mission?
- civilitty 3y agomission [1]: (1) a specific task with which a person or a group is charged (2) a definite military, *naval*, or aerospace task So in answer to your question, yes. If hikers wanted to call their hike a mission it is well within their rights. Merriam-Webster isn’t going to stop them. You should seriously find better things to do with your life than obtuse rebellion against dictionary definitions. It makes you look like an illiterate nonce.

- avidphantasm 3y agoYou're the one who cited the dictionary.
- civilitty 3y agoYou complained about diction. I cited a dictionary.
- wetmore 3y agoIt's actually really common in the outdoor recreation world to refer to an outing of some sort as a mission.
- iancmceachern 3y agoI refer to a trip to the grocery store as a mission sometimes
- harpiaharpyja 3y agoYes, this is not an uncommon usage of the word.
- avidphantasm 3y agoSadly puffery and euphemism are all too common.
- ssnistfajen 3y agoImplosion is probably the second best possible outcome after being rescued. The alternative of slowly running out of oxygen in 96hrs with no possibility to self-rescue is a level of grueling horror no one should experience.
- cyanydeez 3y agoImplosion should hit sensors though. Maybe they just took on water and drowned.
- raxxorraxor 3y agoHow likely is it that they actually have survaced but nobody found them yet? Would sonar pick them up if their engines are out? How likely is a visual contact on the ocean if the sub drifted a few miles?
- c00lio 3y agoUnder water, sonar could pick them up, but sonar is mostly "look down". If a current dragged them somewhere outside the immediate vicinity, they'll be hard to find, because the search vessel needs to be within at most 4km to find them in the water if they are drifting. Far less on the ground, because eliminating and processing ground echos is extremely hard. If they are on the surface, getting them by sonar is not possible, but aerial surveillance might find them. However, things are very hard to see in the ocean if there are waves. They might have an AIS locator which would transmit their position and an emergency signal, but maybe they skimped on that too, because the submarine-rated ones are expensive.
- N19PEDL2 3y agoShouldn't a sudden implosion be easily detected by hydroacoustic buoys? When submarine ARA San Juan collapsed underwater its sound was detected.
- c00lio 3y agoMaybe. Sound travels longer distances in water than in air, but there still is a limit. And hydrophone chains and buoys are probably not dense enough to hear everything. Volume is also an issue, the Titan is far smaller than a military sub, so the sonar spike corresponding to the implosion will be shorter and of a smaller amplitude. The sonar on their surface vessel should have picked up the noise, if they have one that does recordings and passive mode. But I guess they were too cheap for that as well, since no regular sonar surveilance of the sub is mentioned in the press.
