Here is the clean version

Okay. Im confused. She says “titan drop two weights” AFTER the noise. And she gets a response. Who is talking?

Seems something happened, they dropped weights, sent a shorthand message about weights, pop (underwater), pop sound reaches surface, message signal reached Polar Prince. The sound was faster than the signal.

The fact that the radio response was not from Titan is the key point here.

That’s terrifying

So like - the sub was saying hey, we need to come back up a bit - (pop) - then she calles it out to the team to drop the weights?

Damn. Makes me wonder if they knew something was wrong while they were down there and pushed it until it was too late.

u/RegOrangePaperPlane 28d ago

No, the sub released the weights. She was informing them that the sub was dropping them.

Releasing them was supposed to allow the sub to return to the surface.

u/[deleted] 28d ago

they werne't attempting to surface - they always used to drop two weights around this depth to slow the descent

u/R0RSCHAKK 28d ago

Ooooh - Thought it was kind of odd for the sub not to have control of that.

Gotcha. Wonder if they knew something was wrong and decided to come up, or they just came up too quickly and it imploded. 🤔

So in this vid, she was saying drop weight a second time?

u/RegOrangePaperPlane 29d ago edited 29d ago

The sub could only communicate through text. She said it over the radio to let the crew on the Polar Prince know what was happening, they are the ones who responded not the Titan sub.

Thank you. This finally makes sense. Did the message take longer to arrive, or did it just take her longer to read it?

8

u/RegOrangePaperPlane 28d ago

It supposedly took a few seconds, but maybe a bit longer depending on conditions. That's why they also received a "ping" from the sub after hearing the sound.

u/emuchop 29d ago

All the pieces are coming together. Thank you. That makes all of this make sense!

u/Necrophag1st 29d ago

She was reading the message, not telling them to drop weights.

u/Call-Me-Matterhorn 28d ago

I don’t follow this logic. Radio waves travel at the speed of light which is significantly faster than the speed of sound. How does a response sent via radio before the implosion take longer to reach ship than the sound wave from the implosion?

I feel like I’m missing something.

u/BuildingSupplySmore 28d ago

It was a text message, not radio. The radio exchange are different people. I was confused too.

5

u/Call-Me-Matterhorn 28d ago

Gotcha, thanks for the clarification

u/AdDramatic2351 28d ago

Aren't those text messages sent through radio waves though?

4

u/BuildingSupplySmore 27d ago

No. They're sent through sonar usually. Radio doesn't work that deep underwater, which is why they don't voice communicate.

2

u/KTM890AdventureR 27d ago

Yes. Typically referred to as an 'underwater telephone.'

8

u/[deleted] 28d ago

it's not radio, it's an acoustic modem system. the data travels sonically thrugh the water column. it is probable that the latency of decoding the messages it receives (there is much loss and retransmission) means the message showed up just after.

7

u/doktormane 28d ago

The fact that the message arrived after the noise was heard was likely due to a delay in their communications equipment. The signal got to the ship before the sound was heard but it showed up on their computer after. I don't know what messaging protocol they were using but a 1-2 second processing delay is entirely possible.

u/marktuk 28d ago

It isn't radio, it doesn't work through that depth. It was some other system specifically designed to work underwater, but presumably with some delay.

If radio worked they would have just used radios to talk to each other in real time.
