In all my reading of Trek minutia over the years, I have never heard anything about (nor thought about, until just now, to be honest) which production moved into the soundstages used by Star Trek. Did Mission: Impossible take the space? What became of the sets? Destroyed? Recycled, where possible? Sir Rhosis
