The ground control team is making efforts to bring the space travellers back to earth. Meanwhile Mrs Noah and her friends are trying to accustom themselves to life at 35,000mph.

Britannia Seven, Britain's runaway space station, is orbiting the earth at 35,000 mph. On board, Gertrude and Clive await a rescue attempt by a space shuttle.

Mrs Noah is still marooned in Britannia Seven. The rescue vehicle has docked in the space ship, but has damaged a tank, so some of the space travellers can't return to earth.
