This story is weird to me Considering the current geopolitical weather and the presence of Russian submarines, you'd think the US army would be able to locate the missing object in no time, even with a triangulated location, they failed Worrying times

#112It's not clear from the headline - but the debris field is on the ocean floor and was found via the USGC's remote operated submersible vehicle.
Yes on the sea floor but according to BBC: > Debris patch was found by an ROV from the Horizon Arctic, a Canadian commercial vessel which arrived last night near the Titanic wreckage site. > It was loaded with support equipment and was also carrying an Odysseus 6k ROV that can reach depths of 6,000m. https://www.bbc.com/news/live/world-us-canada-65967464?at_bb...

Would the implosion have been loud enough? I mean the thing was a tiny 7x3m cylinder located 700Km from the nearest coast...
How do submarines commonly fail? Is the assumption of a violent implosion warranted? I would think another failure mode could be water rushing in without the overall structure catastrophically failing, which would actually relieve pressure on the structure as it happened and be much less energetic.

#116Why has this sub been so hard to find? I keep seeing reports that they've search an area "the size of" Massachusetts or Connecticut. Shouldn't OceanGate have recorded the exact coordinates where it was released and then been able to localize its possible location to a small area around that by modeling ocean currents or something? My understanding the Titan was designed to sink to the bottom and could only move very…
This is something I'd also like to know. I'd assume they were assuming a worst case scenario of something like a ballast malfunction paired with a propulsion malfunction, so you have a partially buoyant (enough to stay off the ground, not enough to surface) craft being pushed both by currents, and possibly its own propulsion, in an unknown direction in some radius outside of the Titanic. I've no idea of the depth son…

I agree but not at 250k a head. It should be safer, but everything is done to a price point and I'm sure those on board recognised the risk of such an expedition.
I seriously doubt the victims knew how risky this trip was, even though they signed the waivers. Why would you bring along your 19-year-old son if you thought the chance of death was 1/100 or even 1/1000. The CEO, who obviously overestimated the safety of his cost-cutting design, had raised $20M in venture capital, it's not as if he had a death wish either.

I wonder if typical deep sea exploration use relay all along the descent, to ensure comms and raise rescue capabilities.
The three main methods are: acoustic using SONAR to receive data, tether or umbilical cord, and buoy based where the DSV releases a buoy that ascends to the top. Relays don't really work because you'd need a LOT of them and they'd all have to keep themselves positioned within like 30 meters of each other which is very hard with ocean currents. That's with very low bandwidth VLF radio.

#119If it did implode in multiple pieces it means the experts were right; many said that carbon fiber was a poor choice because while it's light, it breaks like glass, contrary to steel which tends to "open" slowly.
Here, it’s in compression, not tension. And its light weight doesn’t matter.

It's a shame they openly did not hire SMEs.
This quote shines light on his hiring philosophy: “When I started the business, one of the things you’ll find, there are other sub-operators out there, but they typically have, uh, gentlemen who are ex-military submariners, and they — you’ll see a whole bunch of 50-year-old white guys,” Rush told Teledyne Marine in a resurfaced interview. “I wanted our team to be younger, to be inspirational and I’m not going to insp…
