Maitland's ship

Captain Maitland's ship was a human spaceship that ventured to Sense Sphere.

History
Thanks to the hostilities of previous humans searching for molybdenum on Sense Sphere, the Sensorites attacked the minds of the crew. Captain Maitland and Carol were put in a death-like form of stasis while periodically awakened and fed by the Sensorites, while the mineralogist John had his mind opened and had turned insane, but could tell good and evil.

The First Doctor landed on this ship and had the lock to his TARDIS stolen by the Sensorites. After John was cured and the planet's disease, in actuality atropine poison in the aqueducts, was figured out by the Doctor on Sense Sphere, the ship returned home. The ship took the surviving members of the last human expedition, who were responsible for poisoning the Sensorites, into custody. (TV: The Sensorites)
