(At around 28:00) As the crew is about to enter the reactor room Captain Crane cocks his .45 caliber 1911 pistol, and the slide locks open. This means the pistol and magazine are empty, which is a common recurring mistake in this series. Crane then attempts to use the left-side slide release to at least bring the slide forward and proceed with the scene. Amusingly he fails, and simply continues the scene with the pistol slide locked open. Needless to say, this pistol is not ready to fire.
