Intro: How can a Concorde supersonic jet disappear into thin air? That is what The Doctor, Adric, Nyssa and Tegan hope to discover. You're welcome to come along as an observer on "Time-Flight."

Outro: Next week, The Doctor's biopattern is stolen from The Matrix on Gallifrey. The council of Time Lords has no option but to urgently summon The Doctor to his home planet. Be with us next Sunday night at 11 when the story unfolds beneath the "Arc of Infinity." [source: ChicagoEpguides]
