So my kid was playing and while attempting to hijack a ship it took off into space. Once he killed the crew he was unable to fly the ship due to having too low of a level. Being overburdened he dumped all of his gear and then fast travelled back to his destination. About an hour later he returned to that planet and found the ship floating in space and when he boarded everything was floating like the power was off. Pretty cool for sure.
Only when I've jumped on top of them as they were taking off just to see what would happen.
(At some point it becomes incorporeal so you just fall through)
You get some serious air, though!
A similar thing happened to me when I was actually attempting to board a ship. As soon as I walked up the hatch and tried to open the door, the hatch closed and the ship started moving. Couldn't enter at that point, and I was also now trapped in the airlock as the ship was taking off into space.
Was actually a bit terrifying, because in theory I was now completely at the mercy of these pirates and had to hope they didn't just jettison me off into space after they noticed I was there. In reality, I just phased out of the ship as it went too high up and was a bit disappointed that nothing that exciting can actually happen.
