 The opening and closing credits of the first episode ("Trapped In  The Sky") differ entirely from the rest of the series: the music  arrangements are slightly different (in the closing credits, for  example, the music for Thunderbird 1s first launch is used); sound  effects are used in the montage (including Kyranos scream); the  Mole is not used as a standard picture in the closing credits. It is  the only episode where Gerry Anderson (I) (qv) and  Sylvia Anderson (I) (qv) are credited for writing an episode of  the show.
