So what I'm getting from this discussion is that we're gonna go in and try to look for coordinates and message logs to find out what happened. To do that we'll need power, which means we'll need a team to go down to engineering and try to switch the old girl on. If the engines are screwed, a ship that size will have auxilary power cores (massive capacitors basically) which could potentially still hold power even ten years later. That would mean we need a minimum of two teams, one at engineering and one at the bridge.
What do we have in the way of comms?
