In the interview I saw this morning on CNN, where Muray mentioned drilling the next (6th) hole, he also mentioned, indirectly, and in my words, that Saturday may be the last day of recovery attempts. The sixth hole should be finished by Saturday, and the indication that Murray made, is that to go beyond Saturday, and, again, in my words, that they would need some concrete reason to continue.
To me, that meant that they needed to find miners alive. If they saw a body, or bodies, as a result, of inserting a camera down the 5th, or 6th, hole, I think that is another call that would have to be made. Drilling a large hole, in an attempt to recover bodies, is going to be a challenge heightened by immense danger, and the potential for additional loss of life.
If it were my decision, knowing how unstable the mountain is, I would not risk a life, at this juncture, to retrieve six dead bodies.
