Actress Liz Morgan, who voiced Destiny and Rhapsody Angels, was overcome with emotion at one point during the dialogue-recording session: "It was a moment when Destiny was very worried about Captain Scarlet and she was making impassioned pleas for him. Well, I started to cry, and immediately a voice came down from the recording booth and Reg Hill, who was directing that particular week, said, 'No, Liz, love. Do it again, love. Puppets don't cry!'" Just before Cloudbase hits the ground, Colonel White is shown standing to attention and saluting in a spiralling freeze-frame shot. Anderson based this on maritime tradition, stating that he wanted the audience to see White "[going down like the captain of a big ship."
