Luanne was the press officer for UK Rocket Project 9.2, the Guinevere One space probe. As the project was top secret, her colleagues Matthew Nicolson and Duerte Rodriguez imagined her job prior to the probe's planned landing on Mars to consist solely of answering the telephone and denying that there was a secret rocket project going on. Despite this, Luanne always managed to look like she was busy. Unbeknownst to any of the British Rocket Group's staff, Luanne actually worked for UNIT as their undercover agent within the Guinevere project. (PROSE: The Christmas Invasion)
