It'll take days, even once the sub is located.Sonar equipment has picked up banging sounds possibly from inside the sub race against time to rescue or just a body retrieval .
Seemingly it only takes 2 hours to get down there but that's with everything on site and them pinpointed . Then you have to grab it somehow and get both back to surface. Also the build up of co2 is a problemThey have until thursday lunchtime til the oxygen runs out; even if they locate the sub they'll have to get down there and back within 24 hours. It'll be a miracle to get them out alive.
great post -more informative than Ive seen by the MSM.When you start to look at the limitations of Sonar scanning esp at that depth it really is a needle in a haystack.
The last ping was approaching the wreck. I still think they suffered a power failure of sorts as the sonar comms stopped, indicating some sort of failure either the power or other issue, had they been tangled in some sort of wreck, i would say comms would still be possible.
Limited knowledge of their setup indicates there may not be much in the way of contingency backup in the event of power failure, unlike aviation and military architecture where multiple levels of redundancy are a must for all components it seems the failure system that would trigger a resurface was also affected here, either by sharing the same power source which failed and or signalling to invoke resurface was unable to activate again due to the lack of redundancy in the design.
This is my theory as the USCG(Cost guard) tweeted they were receiving banging noises over sonar monitors which confirms they are down there somewhere more than likely drifting in a powerless state, with little food/water and very low temps and now 24hrs of oxygen left, it's looking bleak.
If you're aware the black box system in all commercial/military aircraft utilises a ultrasonic sonar ping which can last for up to 30days allowing emergency services to locate the device in depths as deep as the titanic. Why the actual fck did they not even have a simple device on board? Again the fact this Sub avoided any certification or safety assessments is beyond me.
Poor souls, however it should NEVER have been permitted, its clear now this Sub was never approved or passed rigorous structural and standards permitting it to operate at these depths. The costs and man hours already spent searching for this sub must be huge.
There are more and more articles coming out about the sub itself and the company. Distinct lack of proper testing, constructed using questionable methods and materials, lack of recovery strategy should something like this happen. As one expert interviewee put it, yes it's good that humankind wants to push boundaries, however you surely want to do it using equipment that's been tested to rigorous levels and then some, especially if doing something under water.Poor souls, however it should NEVER have been permitted, its clear now this Sub was never approved or passed rigorous structural and standards permitting it to operate at these depths.

Rapid decompression?I'm surprised that it doesn't have a safety feature that it would naturally rise to the surface.

Maybe, however the first issue that occurred was a halt of 2-way comms. You would think the first course of action would be to send out a distress signal, unless the hull breach very quickly compromised the onboard power supplies. However the apparent sonar pickups of them banging on the hull means whatever it was hadn't killed the crew, a structual failure at those depths would pancake them in an instant.Heard someone say that the viewing port on that submersible was certified to depths up to 1300 metres, the Titanic is 4000 metres?, so they might be dead already.
