Tritanic

The Tritanic was a luxury class astroliner of the fifty-ninth century that was built to withstand the time winds of the Kolox Nebula using an experimental time-navigation unit. The time-nav unit attracted the interest of a surviving Skrawn hiveship that boarded the Tritanic and stole it before it was returned by the Doctor. Many passengers died on that particular voyage if not casualties of the Skrawn sting then sucked out into space when the Skarawn ship departed leaving the docking doors unsealed.
