Operation Golden Age

Operation Golden Age was a conspiracy led by Sir Charles Grover and Professor Whitaker (TV: Invasion of the Dinosaurs) in 1974 or 1979. (PROSE: The Enfolded Time)

History
Operation Golden Age included General Finch and Captain Mike Yates, the latter of whom had recently suffered a breakdown that made him more open to their goals.

Believing Earth was becoming too polluted and humanity was too corrupt to change, they developed an elaborate plan to restart civilisation. After evacuating London by bringing dinosaurs to modern times with time eddys, they planned to reverse time around the planet to a period before mankind had evolved, then colonise it with a select group of people who believed they were on a spacecraft heading for New Earth.

The plan was exposed and defeated by the Third Doctor, Sarah Jane Smith and UNIT. Sarah exposed the truth about the spaceship to the colonists, horrifying them since the plan would wipe out whole generations of humans and of history, while the Doctor and UNIT identified the people responsible for the project. Grover and Whitaker transported themselves to a time in the past after attempting to activate a time machine that had been reprogrammed by the Doctor. Finch was subjected to a court-martial and Yates was given sick leave and the chance to quietly resign. (TV: Invasion of the Dinosaurs)

Whitaker's experiments had been funded by Tobias Vaughn. (PROSE: Original Sin)

Legacy
When the Doctor and Sarah found themselves in Siberia, Sarah initially refused to believe it and likened it to the "Golden Age mob" and their fake spaceship. (AUDIO: Kaleidoscope)
