One thing (apart from many others) needs an urgent explanation IMO -
why is the central shaft being emptied of polystyrene now when it was always scheduled to be done only when the base had been fully stabilised?
Aye. Especially when we were told that:

"The polystyrene in the summit crater would only be replaced with chalk once the voids at the base had been filled or supported, because of the additional weight loading."

Makes you wonder, doesn't it?

The other scenario is that it is intended to leave the shaft empty until the base is stable enough to put the chalk in, which will be a while, if ever, presumably.

But that begs the question, if its safe not to have polystyrene in there, why did they put polystyrene in there??
