Recovery 7

Recovery 7 was a recovery craft sent up to Mars Probe 7 to check on their communication equipment and see if the astronauts were fine and well. The craft was taken over by Alien Ambassadors and subsequently flown to Earth. The Doctor took control of Recovery 7 for a time so he could fly up and negotiate with the Ambassadors Leader. In the end the Ambassadors were flown up in the craft to re-join their people and the lost astronauts piloted Recovery 7 to Earth and safely rejoined society. (DW: The Ambassadors of Death)
