Phoenix. Modifications include the reverse-polarisation of the electrical circuits. Ross blasts off in the spacecraft, which he has named Doppelganger, and attempts to dock with Phoenix. However, the electrical systems malfunction, crippling the spacecraft, causing it to fall back towards the Space Centre. EUROSEC are unable to correct the fault and Doppelganger crashes into a parked spacecraft, killing Ross and starting a chain reaction that destroys much of the Space Centre. All records of Ross's presence on the Counter-Earth are lost in the disaster. Years later, former EUROSEC director Jason Webb, now confined to a wheelchair and in a much diminished mental state, is admitted to a nursing home. He sees his reflection in a mirror. He rolls forward quickly, trying to touch his doppelgänger, but crashes into the mirror and dies.

Kanter was open to funding promising film ideas, so Lew Grade, the Andersons' employer and financial backer, set up a meeting for Gerry Anderson to pitch a story about a hypothetical "mirror" Earth. On the inspiration for the film, Anderson said: "I thought, rather naively, what if there was another planet on the other side of the Sun, orbiting at exactly the same speed and the same size as Earth? That idea then developed into the planet being a replicated Earth and that's how it ended up, a mirrored planet". Writing Assisted by Tony Williamson, Anderson and his
