More on the missing sub
Jun. 21st, 2023 09:24 amSome very interesting stuff in this article from National Public Radio. They sent a correspondent on a dive, and he reported that there are seven different ways for the sub to jettison weight for an emergency surface, including an automatic method with a dissolving rope!
From the article: "What you can do is rise to the surface. And there are seven different ways to return to the surface. Just redundancy after redundancy. They can drop sandbags, they can drop lead pipes, they can inflate a balloon, they can use the thrusters. They can even jettison the legs of the sub to lose weight. And some of these, by the way, work even if the power is out and even if everyone on board is passed out. So there's sort of a dead man's switch such that the hooks holding on to sandbags dissolve after a certain number of hours in the water, release the sandbags and bring you to the surface, even if you're unconscious."
So it might be sitting on the surface of the ocean, just currently undetected: one problem is that the seas in that area are six foot white caps, and I don't know why unless it's for photography/aesthetic reasons, the submersible is WHITE. A nice addition would be a radio transponder that activates when exposed to air. I'd want it painted in squares of black, white, and safety orange. Something easily spotted from the air.
I think today or tomorrow is pretty much the limit for their air.
At least with having heard banging, the search coordinators have an area that they can concentrate their efforts in. But it is still pretty grim odds.
If it did sink to the bottom of the ocean, the US Navy does have a recovery vehicle capable of working at such depth: it recovered an F-35 aircraft last year off the South China Sea that had a bit of a misfortune while trying to land on a carrier. But I read something about the ship that could carry it what was based closest to that part of the Atlantic was decommissioned last year.
