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?
If you can drop an emergency beacon they may as well drop emergency weights and surface. Even if we knew exactly where they were a recovery at 4km deep is not guaranteed. Better to be on the surface.
Tethers don’t work at that depth for a variety of reasons. One being that the surface boat drifts around on the surface and it would pull the sub all over the place. The sub goes under and the boat ‘stays in the area’ not right on top of them.
