Thank you. And I feel vindicated in an early decision today. I built my turbolifts with an internal and external door, like an elevator would have. I couldn't remember ever seeing it in the show; but, it seemed right. And today, for the first time, I caught it. In the Corbomite maneuver at about the 7 minute mark - grey inner door. Don't know how I missed it for all these years; but, finally.. lol.
Ok, back to work with me.
