 With Max Capricorn dead , the Heavenly Host divert to the next highest authority , the Doctor , and aid him in quickly reaching the bridge . Together with Midshipman Frame , he uses the heat from the entry into the Earth 's atmosphere to restart the ship 's auxiliary engines . The ship stabilises and narrowly avoids a collision with Buckingham Palace . The Doctor then realizes that Astrid was wearing a teleport bracelet when she fell into the engine . In an emergency , the teleport bracelets were programmed to hold a person 's molecular pattern in stasis until it can be recovered . The Doctor frantically attempts to retrieve Astrid 's pattern , but the machine is too badly damaged . The Doctor reluctantly allows the ghostly remains of Astrid 's atoms to dissipate into space . As the surviving passengers wait for rescue , the Doctor and Mr. Copper , who would otherwise be sent to prison for committing fraud in order to get a job with the company , teleport to Earth and find that the TARDIS landed unharmed , thrown from the ship after the collision . An ecstatic Mr. Copper is left to live on Earth with a credit card he preloaded with a million pounds , unaware of the conversion between pound sterling and Sto credits .
