23 years ago today, James Doohan reprised his iconic “Star Trek” role as Montgomery Scott when he appeared in an episode of “Star Trek: The Next Generation.”

In that October 12, 1992 episode, written by Ronald D. Moore, the crew of the Enterprise discover Scotty’s life form on a Federation transport ship that’s been missing for 75 years. Rematerialized aboard the Enterprise, Scotty raises a glass to his absent crew members. We raise a glass to sci-fi logic that gives us the return of characters who should be long-dead.

It was the first “Star Trek” episode directed by Alexander Singer, who went on to direct several more “TNG,” “Deep Space Nine” and “Voyager” episodes. “Having Jimmy Doohan there, I felt I was in the middle of some kind of mythic experience,” he later said.
