Space Station Alpha (The Snag Finders)

 Space Station Alpha was the largest artificial satellite in orbit around planet Earth around 3769. It was many years in construction and utilised an army of engineers, construction workers and robots (employing many Technomatics).

Around this time, some five years into its construction, the Klytode attempted to blow it up with a cobalt bomb, and sending the space station crashing into the Earth, catastrophically changing its climate. The plan was thwarted by the Doctor who ejected the bomb into space.

Incidently, snag finders (low-level construction inspectors) Jimmy and Welding Bot X-5 ‘Bert’, successfully went on to live the career of their dreams following the Klyptode’s capture and arrest. (DWAM: The Snag Finders)
