Theory:Doctor Who television discontinuity and plot holes/The Green Death

From Tardis Wiki, the free Doctor Who reference
You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which The Green Death doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 
  • Why is the mine still being checked if it's been closed down as an uneconomic pit (cf. the sealing of mines in 1992)?
Ecological reasons.
It is actually an important consideration in the mining industry. Closed mines pose risks such as water pollution, earth tremors, sink holes. Be sure to budget for this if you ever start a mining company.
  • Why is there a camera in a pipeline?
To check for obstructions.
  • The Doctor resists BOSS's programming by calculating Pi. He recites the first five numbers and continues silently. But he gets it wrong, giving the first five digits as 3.1416. This is only correct if Pi is rounded off after five digits. The correct sequence would be 3.14159265…
The rounded number is good enough for his equation, then he silently continues calculating the equation, not reciting Pi.
  • When Jo goes to get Professor Jones a maggot, why doesn't she grab the first one she comes to instead of going out into the midst of them?
She may be looking for one that isn't too close to any others. She wouldn't want to risk getting attacked while preoccupied.
