Doctor Who: 5 Reasons To Remember The Dalek Invasion Of Earth

2. The Ongoing Plot To Steal Earth One thing that was never explained at the time was the exact nature of the Dalek plan. Why did they want to dig a tunnel into the Earth and use it as a dirigible planet? This is a plot that was returned to by Big Finish in their Eighth Doctor Adventures in the stories Lucie Miller and To the Death with great effect but we had to wait for the RTD era to get an explanation of sorts. Yes we had to wait for the Tenth Doctor stories The Stolen Earth and Journey's End in which the Daleks dispensed with mighty engines and whisked the whole planet off to form part of its universe destroying device.
