Don't forget there is now only a short window (24 hours) to rescue people trapped inside the titan.
Extraction might be a little harder than bombing runs, so I recommend brushing up on a guide to it.
The summary is that you need Surface Extraction Missiles (obtained in the Mining equipment section of outfitting), and a Pulse Wave Xeno Scanner, which is a utility, so you likely have to sacrifice a heat sink or caustic sink to fit it in, which increases the difficulty a little.
You use the scanner to find the humans. It finds several features, but the ones you're looking for are called... crap I forget, it's something that means "underground storage chamber"
Select the chamber, fire an extraction missile, but don't release the fire button: extraction missiles need to drill and they stop when you release the button. Look at the scanner to the lower left for a depth chart, when the missile passes through the blue band, release the button. If you release within the blue band, the extraction will succeed, releasing several pods (each containing a person).
Then you use collector limpets to scoop as many as you can before a ton of angry thargoids arrive.
Now that Cocijo is in meltdown, maybe the angry thargoid response doesn't happen?
Note, you'll also likely be interdicted as you leave the system, and they'll attempt to hatch-break and retrieve the pods. So have ECM or point defense, or a fast ship.
Pods can be dropped off at Search and Rescue at a station or rescue ship.
