In an emergency the Banshee Circuits allow a TARDIS to use any resources available (including people, places, dreams and memories) to ensure the survival of the Capsule and its Time Lord Operator. If necessary, parts of a TARDIS interior will dissolve into viscous metallic liquid as a TARDIS diverts resources to the Molecular Stabilizers. In certain extreme situations the TARDIS will dematerialize as soon as the operator enters the ship. The Banshee Circuits also serve as the Flight Recorder.
