Has an astronaut ever become disconnected from his ship and floated into outer space? If not, could that happen or would they simply hover where they were if they got disconnected? I have heard astronauts have jet packs on their suit but I'm thinking the scenario something along the lines of:
Astronaut goes to do some maintenance on his ship so goes for a wee walk
He clunks his head of a wing and knocked unconscious and accidently disconnects his thing that connects him to the ship (I know, I know, there will be all sorts of saftey mechanisms to stop this happening, but roll with it)
As he is unconscious, he cant use his jet pack, does he float away? Or does someone stick out a big pole and try and hook him back in?
