Pluto-Earth flight one-five

Pluto-Earth flight one-five was a space flight from Pluto to Earth.

Colville was a crewmember on the flight and responded to Warner's call from Nerva Beacon. Warner informed Colville that they had a plague infection, so their stopover was transferred to Ganymede Beacon. Colville understood, and then asked for news of his brother, Crewmaster Colville, who was doing a tour on Nerva. Warner, on orders from Commander Stevenson, said his brother was fine, when in fact he had been killed by the Cybermats. (TV: Revenge of the Cybermen)
