An aircraft heard sounds at 30-minute intervals from the area where the sub disappeared, according to internal e-mails sent to DHS leadership obtained by Rolling Stone
Nightmare fuel. Even if they find them, I don’t know if they can get them to the surface before the oxygen runs out.
Assuming they’re on the bottom, they’d have to get a ship with about 4 km of cable to pull them up. (More probably. The titanic is at about 3.8km; as well as the ROVs
I’m not sure it has a hatch that can be used to transfer passengers onto a rescue sub. Kinda sounds like it doesn’t. (Assuming they even have a rescue sub in the area.)
The Titan does not have an externally opening hatch at all. The surface crew actually bolts and torques the front section of the submersible in place.
Once/if the Titan is located (itself a huge challenge), the only way the Titan can be rescued is by either repairing the submersible underwater so that it can float to the surface under its own power or by affixing a 4km tow cable to it and winching it to the surface. Only at the surface can they crack it open without killing everyone onboard.
Supposedly they have electric heating. Hopefully that system is still operational.
I assume one of three things happened- they somehow got snagged on something coming and can’t pull free. (This makes little sense, since… any competent engineer wouldn’t have stuff to get snagged in the first place and there’s not much down there to get snagged on, except the wreck itself.)
They could have suffered a leak in the buoyancy tanks preventing their return, this seems a bit more likely.
Or they had a failure in the electronics- a short in the electrical system could leave them without power.
The banging rules out the fourth- a leak in the pressure vessel (which at depth they wouldn’t live long enough to know.)
