SS Pentallian
The SS Pentallian was a cargo ship in the 42nd century.
The ship's captain, Kath McDonnell, had illegally stolen some gas from the Torajii sun, not knowing that the sun was alive. Torajii was angered and used its gas to possess members of the crew to kill the remaining crew one by one. The ship was also sabotaged so it would collide into Torajii, destroying itself. When the gas was released, Torajii left the crew alone and let them leave. (DW: 42)
The SS Pentallian was apparently using sun fuel to power itself up, but the sun was alive, possessing Korwin McDonnell, who began a murderous rampage through the ship.
The ship possessed heat shielding to protect the ship from intense heat. However, the hotter the outer hull gets, the weaker those shields become.
Machinery
The ship also had escape pods, which Martha Jones used along with Riley Vashtee, as well as a security system unlocked by trivia questions from a drunken night; according to Vashtee, only the crew knew them.
