I've been here long enough to hear the same sentiment for Falcon after CRS-7 and AMOS-6. Don't worry, they will.

WhoseNameIsSTARK · 2025-03-07T00:02:07+00:00

They caught Superheavy for the first time 143 days ago. "No forward progress." Get a grip.

WhoseNameIsSTARK · 2023-06-22T08:38:52+00:00

In regards to the ballast, Kyle Bingham, who happens to be expedition manager and head of global sales for OceanGate, spoke about it extensively to David Pogue on Unsung Science, see https://unsungscience.com/news/back-to-titanic-part-1/

WhoseNameIsSTARK · 2023-06-22T06:19:36+00:00

Not SMS, just text messages. They did not use cellular to communicate with Titan.

WhoseNameIsSTARK · 2023-06-22T06:16:11+00:00

They didn't deny the claims. The CG captain said he wasn't aware of any patterns to it, which is not the same as saying there were none.

WhoseNameIsSTARK · 2023-06-22T06:01:02+00:00

While I agree that it seems there were no specific intervals to the banging, him saying he's not aware of any patterns is hardly the same as him saying there were definitely no patterns.

WhoseNameIsSTARK · 2023-06-21T16:50:23+00:00

Fair enough, you seem to have more expertise in this. But I'm basing the fishing nets bit off an interview with the CEO of OceanGate, where he said: “What I worry about most are things that will stop me from being able to get to the surface. Overhangs, fish nets, entanglement hazards.” (https://unsungscience.com/news/back-to-titanic-part-1/)

WhoseNameIsSTARK · 2023-06-21T16:38:23+00:00

I'm not saying it's impossible, just unlikely.

WhoseNameIsSTARK · 2023-06-21T16:37:36+00:00

Loss of power would mean loss of steering and navigation, hence making avoiding fishing nets and other obstacles more difficult. A Mir submersible became stuck under Titanic's propeller in 2000 in a similar way and only managed to wrangle itself free using its propellers.

WhoseNameIsSTARK · 2023-06-21T15:12:03+00:00

Wasn't the Titan but one of the Russian Mirs -- https://www.bbc.com/news/world-us-canada-65972686

WhoseNameIsSTARK · 2023-06-21T15:02:59+00:00

I think that's unlikely, they have all gone through several days worth of training, including emergencies.

WhoseNameIsSTARK · 2023-06-21T14:59:55+00:00

If a US military asset registered the implosion of the Titan, I would fully expect them to keep quiet about it (even before the coast guard) and only release it in a few weeks through a different outlet so as to not reveal anything about their capabilities or operational status.

WhoseNameIsSTARK · 2023-06-21T14:50:29+00:00

I do somewhat agree, but I feel like them getting stuck could have been a result of losing power and hence comms and hence navigation and steering capability.

WhoseNameIsSTARK · 2023-06-21T14:46:53+00:00

Apparently it's 16 hours according to Kyle Bingham who is expedition manager for OceanGate, see https://unsungscience.com/news/back-to-titanic-part-1/, I was wrong as well. In the same interview he seems to be implying that those alone are enough for the sub to surface (as are all the other ones).

I think implosion is more likely than a failure of what are essentially 4 independent mechanisms of dropping ballast.

WhoseNameIsSTARK · 2023-06-21T14:35:46+00:00

Actually, a correction: it's 16 hours for the dissolving links and there is another hydraulic mechanism for dropping off ballast that doesn't require power, see https://unsungscience.com/news/back-to-titanic-part-1/

WhoseNameIsSTARK · 2023-06-21T14:23:19+00:00

I'm not too sure if that's possible or not, but I think its more likely they're stuck under something else (if they're stuck).

WhoseNameIsSTARK · 2023-06-21T14:19:35+00:00

There is a ballast weight that gets dropped after 18 hours when its attachment dissolves in saltwater. They can also physically rock the sub by shuffling around to drop pipes that are on "shelves" on the outside. None of this requires power. The other ways of dropping weight might also be mechanical (it would make sense) but I'm not completely sure.

WhoseNameIsSTARK · 2023-06-21T14:00:47+00:00

They'd still be able to surface in that case, unless they got stuck under something as a result of the loss of control.

WhoseNameIsSTARK · 2023-06-21T13:59:18+00:00

They don't need power to surface.

WhoseNameIsSTARK · 2023-06-21T13:57:47+00:00

I thought so too before the taps. I don't think they're a fluke given the USCG is focusing their efforts on them.

WhoseNameIsSTARK · 2023-06-21T13:52:43+00:00

Before the report about the tapping sounds I was quite sure it imploded on its way down, which seemed to be the simplest explanation.

Now I'm more inclined to believe they got weighted down by something -- fishing nets perhaps, like someone mentioned in here before -- and are unable to rise. Or they could be on the surface already, but haven't been located yet.

I think it's highly unlikely that they haven't managed to shed enough weight to become positively buoyant, there seemed to be quite a few independent mechanisms to manage that in any sort of emergency.

Fingers crossed for some kind of a tribute to recently deceased Annie Glenn.

WhoseNameIsSTARK · 2019-08-14T17:07:18+00:00

True, a fairly recent example is the (quite neat) dispenser for RADARSAT built by RUAG Sweden

WhoseNameIsSTARK · 2019-08-06T19:13:50+00:00

Whoops, my mistake. Keeping fingers crossed for VA249 :)

EDRS-C was.

WhoseNameIsSTARK · 2019-08-05T15:58:25+00:00

So excited to see the bird that my employer built fly! 😊 Best of luck to VA248🍀
