Dalek Time Squad's saucer

During the Kotturuh crisis, the Dalek Time Squad travelled back to the Dark Times in a Dalek saucer after the Eighth Doctor connected its engines to those of his TARDIS. (AUDIO: The Enemy of My Enemy) The saucer was used during the Battle of Mordeela and to explore the Dark Times. After completing their Symbiont, the Time Squad used it to attack Gallifrey. An explosive in the saucer's engines was detonated by the Eighth Doctor, forcing it into the Time Vortex. (PROSE: All Flesh is Grass) He continued to sabotage the saucer, eventually resulting in it breaking apart in the Vortex. (AUDIO: Mutually Assured Destruction)
