Doesn't it show them flying in space in spacesuits, or am I thinking of another episode? As for the 60mph thing, that's only at the edge of the main body of the station--at the centreline there would be rotation but very little linear speed, so they could potentially either go down a passage from the rotating part to the stationary part, or else pop out of a door at the narrowest part of the rotating station and fly over from there.
