Sanctuary Base 6 rocket

The Sanctuary Base 6 rocket was the last chance of escape from Krop Tor for the Sanctuary Base 6 crew. It travelled to the planet via a gravity funnel, and could escape by the funnel. When The Beast started to escape, the rocket was nearly sucked into the black hole, until the Tenth Doctor used the TARDIS to tow away the rocket. (DW: The Satan Pit)

A similar ship took Klineman Halpen to Ood Operations on the Ood-Sphere, which suggests that this was not just an escape rocket. (DW: Planet of the Ood)
