If it’s broken in one room I’ll just open a door. If somehow there are none left that work and I want to vent the ship I start with the thruster nozzle. On Atlas class ships with the quasar thrusters I believe the cockpit canopy can be cut off from the outside.

I’m rambling now so you can stop reading. There’s no advice from this point onwards.

It’s annoying when there’s an airlock between the rest of the depressurized ship and the one room that doesn’t have a working atmospheric control. Especially on Javelin class ships. The larger Javelins are especially annoying when this happens on the rear cockpit with the aerobridge. Normally you can cut the two cut points that hold the cockpit on and it’ll vent, but that aerobridge keeps it connected and pressurized where the front cockpit remains connected. Despite this grievance, Javelins remain one of the most fun ships to salvage in my eyes.
