>> joining us now is one of the men responsible for punching that rescue down into the mine faster than anyone could hope. jeff hart knows drilling and knows life and death. his last gig was in afghanistan he's an engineer with the lane christensen company. and i spoke with him moments after the first miner was brought to the surface. congratulations. what was it like for you to see this first man being brought out alive after you have been working on this and your colleagues around the clock to make sure this happens? >> we worked real long and hard on that. and to actually see that capsule come through the first time through the hole that we drilled is just unbelievable. we're all kind of in disbelief that we're part of this. >> you had more than a part and your colleagues as well. you worked around the clock, three different drills, plan a, b and c. you were plan b. you actually started later but you broke through first. i read that you said this was the most difficult drilling process you've worked on and you just came back from afghanistan
