Star Trek‘s Lt. Montgomery Scott (James Doohan) made a long-awaited confession about his engineering prowess in Star Trek III: The Search for Spock. Throughout the three seasons of Star Trek: The Original Series, Scotty gained a reputation as a “miracle worker” for his ability to fix almost any engineering-related problem. As Chief Engineer on the USS Enterprise of Captain James T. Kirk (William Shatner), Scotty maintained the ship’s engines, as well as the transporter. Scotty was more familiar with the Enterprise’s engines than anyone else, and he was responsible for saving the ship and its crew on numerous occasions.
