Operation Time Fracture

Operation Time Fracture was the operation by UNIT to send a human team through the Time Fracture using the Portal Stabilisation Gateway and, if possible, discover whatever was causing it on the other side.

UNIT initially wanted to send some of their own top operatives on the mission, but at the last minute, the Doctor vetoed this part of the plan and substituted their own list of trustworthy people, all of them civilians with no prior association with UNIT. Kate Stewart reluctantly acquiesced to the Doctor's request and wrote to the people on the list to explain the Fracture and the mission to them. (PROSE: Welcome to Operation Time Fracture) One of them was Tia Kofi, who had been contacted by the Eleventh Doctor. Doctor Errol Courtney, in charge of briefing the newcomers, found it frustrating that most of them had no knowledge of things like astrophysics and quantum mechanics. (WC: Tia Kofi Enters the Time Fracture!) UNIT also issued Field Logs to the participants, warning them from engaging with the Cybermen who had began to appear as a result of the Time Fracture.

Robert Dudley would sign off his transmissions to the UNIT Black Site with an Operation Time Fracture insignia. (WC: This is Sergeant Robert Dudley., Dudley here., Is anyone receiving these transmissions?)
