Saturnius

The Saturnius was a spaceship that left Earth to investigate the sudden appearance of a mysterious planet. It collided with the Doctor's TARDIS, causing temporal anomalies and affected the crew's memories, meaning that River Song, a freelance aboard the ship, did not recognise the Seventh Doctor and he was believed to be a stowaway. With his help, the situation was resolved. However, the ship crashed onto the planet, resulting in the deaths of all of the crew but River. (AUDIO: The Unknown)
