  • Trivia

    • When beamed up (and before on the planet) the Kirks had no chest insignia on their uniforms, yet as they both started to wander the ship, the insignia was present on both with no time for either to have got changed. Indeed, the first place good Kirk goes is to his quarters at which point he changes into the green uniform, but this was after the insignia had appeared.
