Fair enough. You caught me at a grouchy moment.

Back to the OP:

The complexities of a rescue in such a tight cave boggle my mind. It must have been serious if they were willing to use an air chisel. As I understand it, people in the caving community are quite protective of the caves themselves, and are adamant about no-trace, no modification. They been known to deliberately break a collar bone, for example, to get someone out of a squeeze.
