dr. grossman had to do an amputation on a girl. once we go to a more aggressive posture in the building, taking out concrete, we may find voids where we might find people still viable. >> eric, i understand that there was some frightening moment earlier today, the floor over the rescue workers' heads buckled. what happened? >> when i was with the victim there in the tunnel, there was a lot of debris, obviously from the collapse. i went crawling through the narrow space. there is debris falling down, and at the same time i am pushing the debris behind me to the other rescue worker that we just created, making it possible so the victim could be pulled out through the tunnel that i was creating. and as i am doing it, i have to be really careful for the debris that is coming down from the above area and particularly i am wearing a helmet that now i am with the victim that doesn't have a helmet. so i have to be very caution, what i am removing and where i am pushing the debris. >> larry: dr. grossman, have you done a lot of amputations?

dr. mark grossman, also of task force two. and eric ficus, the south urban as well paramedic for pembroke pines, florida, the town where mimi dittmer is from. how do you explain this? how did she live? >> well, i think by the grace of god, as mimi said. and with some help from us. when i first saw mimi come out after hours of guiding the operations and all these guys that were in the hole with her, and she started reciting all her information down to her driver's license number in detail, i really was anxious that when i was going to make the call, something might not be right. so we had a lot of pensive pauses there between ricky and i. and i said, is this a family member of mimi dittmer? and he answered yes. then my stomach kind of knotted up. then i thought to myself, what would i want to hear first if i was the person receive the message. and i said, your mother is fine. and then there was a huge pause, and then an exclamation from ricky. my heart sank there for a second. then we have a conversation. >> larry: you have eve

dr. grossman, what medical treatment was immediately applied to mimi? hole. she was stuck in the hole obviously for five days. and even once she got out of the hole, the area was contaminated. we had been digs, and dust and food rothing and things going on. just to get her out of the area. but really, she was awake and talking and relatively stable. just dehydration and reassurance. and again, remarkably, she didn't need that much intervention. he was intact. didn't have broken bones or anything obvious. >> larry: eric, how do you explain it? >> well, the minute i touched mimi and when i finally made a contact with her, i knew she would be safe. and i decided to do at that point, just been there by myself, and another member from new york task force, tom, he was just in the hole with me. but he was farther away, closer to the opening that we made. i knew she could be safe. my only concern was that there was a really small, narrow space to get her through. which we were successful and it went very well. >> larry: mimi, what would you like to say to these
