For those who are unaware: A couple billionaires, a pilot, and one of the billionaires’ son are currently stuck inside an extremely tiny sub a couple thousand meters under the sea (inside of the sub with the guys above).
They were supposed to dive down to the titanic, but lost connection about halfway down. They’ve been missing for the past 48 hours, and have 2 days until the oxygen in the sub runs out. Do you think they’ll make it?
I don’t think it’s looking good. If they’re at depth, I don’t even know how they would be rescued
An ROV could attach a couple lift bags to it, fill them and bob it to the surface for retrieval, but the problem would be that it would take a lot of compressed gas to get the initial lift considering 13,000 ft is like 385 atm. Once it gets moving though, watch out!
