If we have something below that, it could be one of two things. there could be a small leak or there could also be a condition where you've had some depletion of the reservoir. when you draw the fluid -- in your example that you gave in letting air out of a tire, if you let some air out of a tire and you stop, the pressure is going to be lower. that's what you're seeing. unlike the tire, in a reservoir, oil and gas can fill in from the outer reaches of that reservoir and start to build that pressure up slowly. and that's what we're seeing. it's building up slowly as that pressure comes back in...

When you have an explosion in your experience of this strength, of this depth, would there not have been a methane sense or some gas sensor that should have given them if only for a second some warning? >> well, you can install what we call minewide monitoring systems and these systems can be located throughout the mine and give you continuous readouts on methane content, carbon monoxide content, et cetera. i do not know if that mine had that. i suspect it probably did not. and that the gas ratings were being done with hand-held monitors. there was obviously a fire boss or a preshift inspectio...

Methane as well as carbon monoxide, the methane is explosive. from about 5 to 15%, so once the air with the methane content got above 5%, it was too dangerous for the teams to work in there. just a spark could cause another explosion. >> given the fact they think it's a long shot to find these four miners alive and they're not willing to risk the lives of the rescue crew to get in there. thank you. >> you're welcome. the u.s. military has confirmed the latest hostage video released by the taliban is that of private first class bergdahl. he disappeared in june 2009. in this video, bergdahl sa...

Feet of air delivered to various places in the mine. the gas levels have to be down below -- the methane content has to be down below 1%. so my question is if he was getting this many citations, the ventilation system was not delivering that amount of air to those places and i would question if the ventilation system was capable of actually doing what the operator said it was doing and msha's citations could validate that question. >> i have a list in my hand of all the citations just this year and it's several pages long. one of the things the governor said today at a briefing this morning st...

And it's -- they're very understanding. bruce dial has investigating several mine fatalities. let's go back to this morning when they said, we have to get these crews out of there. so close. just about 1,000 feet away from a rescue chamber. put that into perspective for us. >> what they did after they drilled the hole frs the surface down to help ventilate the area, they sent the crews back in. well, these holes that they're putting down would only allow about 850 cubic feet of air into the that area. so the content, the methane content of 5.4% was still there. which is too high to take the ch...
