Day of the Daleks (airdate April 2, 1989 [I think])
Intro: Tonight, the metaphysics of time travel come once more into play. Can beings travel into the past to prevent an occurrence in the future, which is actually their present? Or put another way, can history be undone to save the future? Am I making myself clear? Never mind. All will become pellucid as the "Day of the Daleks" unfolds.
"Next Week": The planet Peladon has applied for membership to the Galactic Federation. Next week, at the behest of the Time Lords, the Doctor and Jo will journey thence to assess their candidacy. Be with us next Sunday at 11, and learn the consequences of... "The Curse of Peladon."
