and where did you hear that?

Lots of rumbling and falling earth sounds. Chalk dust coming from the ceiling

That's exactly what I've heard from THREE different people who've been in there, fine chalk dust in the atmosphere and horrible rumbles from falls during their visit.

What is concerning isn't the fact itself, its obviously true and has to be accepted, but two other things:

a.) The official accounts have never given the public the least inkling that things are as dire as that (and dire HAS to be the word, it can't be spun otherwise)

b.) The same account has been given by someone who was in there in March as well as two who were in there more recently so it looks like there have been falls going on for pretty well 7 months.
