The Osterhagen Key, used by Martha Jones and seven other people in the episode 'Journey's End', is a network of 25 nuclear devices placed at strategic locations underneath the Earth's crust. In the event that the suffering of the human race is deemed too great, the devices are to be detonated, and the Earth destroyed. Martha uses it as a threat towards the Daleks as Earth is one of the 27 planets needed to complete the 'reality bomb' which Davros intends to use to destroy the universe.
