@astek333 I don't know, probably some astronauts with magnet boots checking for any damage that was not detected by the ship's auto-repair mechanism...
To make the ragdolls float you click on a ragdolls body and go to ''Geometry Controller...''
Then set the ''Controller menu'' to a,w,s,d (or arrows) and set ''Controller Acceleration'' to about 60.
You can do that with anything and make your own stuff.
