Jack (Death to the Daleks)

A spaceman, known as Jack, was part of the Marine Space Corps expedition to Exxilon in search of the rare mineral parrinium, which was found in vast quantities on that world and desperately needed to cure a galactic plague.

Biography
While investigating the surface of the planet one night, shortly after the MSC spaceship was forced down by the power drain caused by the glowing beacon atop the Great City of the Exxilons, Jack was killed by an Exxilon arrow and tumbled down a slope into a lake.

When he failed to return, two of his colleagues, Captain Richard Railton and Lieutenant Dan Galloway, went out the next morning to try to find him but, on returning to their base with the Third Doctor, had to tell Jill Tarrant their search had been unsuccessful. (TV: Death to the Daleks)

Behind the scenes

 * The spaceman was played by Terry Walsh, who was uncredited on-screen for part one but credited in Radio Times.
 * When Death to the Daleks was broadcast in Australia, the story's opening scene of the spaceman being killed by an Exxilon arrow was edited out by the Australian Film Censorship Board (now the Australian Classification Board) as being unsuitable for family viewing.
 * The spaceman's name, Jack, is used only once on-screen in part one, when Jill asks Captain Railton and Galloway if they managed to find him.
