NPR has someone on that had done the trip and said there are multiple systems in place to surface the sub in an emergency, including some that happen automatically. So there's a very good chance that they're at the surface, but still very hard to find because it's a 20-ft sub in a huge search area. And they're still running out of air because the hatch must be opened from the outside.
They could also be stuck on something no? Those fail-safes assume you can float up

That seems like a...pretty big oversight. Is that standard?
