POB ships have a loot container and asteroid resource cargo hold. POB ship loot container can be accessed by any player inside a ship with admin permissions, you can designate loot manager role to one of them so a pilot and the gunners can do their work uninterrupted - this is intended way of doing things out there.
In case of cargo hold right now - the option to unload it is limited to the ground and is a radial menu option for a ship control device in a datapad, we may have some way to unload it while in space at some point, not sure how/when, but its a thing that would be useful.
