Emergency Program One
Emergency Program One. Research needs to be done to determine whether program as in a computer program, is spelled the same trans-Atlantically.
Talk about it here.
Emergency Programme One was a feature of the Doctor's TARDIS designed to return a companion to a designated place in case of extreme emergency (TV: The Parting of the Ways)
The Tenth Doctor mentioned that Emergency Programme One was automatically activated after five hours. (TV: Silence in the Library) When activated, it projected a hologram recording which explained the programme. (TV: The Parting of the Ways)
Believing that he would die on the Game Station, the Ninth Doctor used it to play a message for the benefit of Rose Tyler before the TARDIS returned Rose to her home of Powell Estate in 2006. (TV: The Parting of the Ways).
Donna Noble recorded a message on it as a way to say goodbye to the Tenth Doctor, in the event that she might not have a chance to do so herself. (COMIC: The Time of My Life)
The visual appearance of the hologram was similar to the visual effect of Security Protocol 712. (TV: Blink)
