Roof mechanism

Torchwood Tower included a loading bay with a roof mechanism. (PROSE: ) In the Battle of Canary Wharf, the Cult of Skaro fought their way into the loading bay and, once in position, Dalek Sec overrode the roof mechanism, allowing the four Daleks to elevate into the sky along with the Genesis Ark, which was then opened above London.
