Handbrake
From Tardis Wiki, the free Doctor Who reference
The handbrake was a device on the TARDIS used for quick stops. (TV: Doctor Who, GAME: TARDIS) On Martha Jones's first TARDIS trip, the Tenth Doctor listed the handbrake among steps for taking off. (TV: Smith and Jones) River Song once claimed that the TARDIS made its "whoosh" noise because the Doctor had left the handbrake on. (TV: The Time of Angels)
