When the Vault Dweller enters the map, all that can be seen (beyond the usual desert dust) is a large blue police call box. These were a common sight on the island of Great Britain during the 1960s. When the Vault Dweller approaches this strangely-located object, the light on top starts spinning, and the box slowly vanishes into thin air with a whooshing sound, leaving behind only a motion sensor.
Behind the scenes
This encounter is a reference to the British sci-fi show Doctor Who, and the blue box is the Doctor's time travel machine, the TARDIS (Time And Relative Dimension In Space), which is bigger on the inside.
- The white panel, indicating the front of the machine and in the show read "Pull to Open", is incorrectly on the right side of the box as opposed to the left, which did happen on Doctor Who between 1966 and 1968. Additionally, the sound the TARDIS makes whilst vanishing is quite different from the distinctive sound effect the show uses.
