>> yes. >> those families are looking at the scene. they just arrived and they are saying, there's no hope. there can't be. what would you say to them? >> people's thought the same thing in the other disasters that we have. oklahoma city bombing all the way to the haiti earthquake. and victims were, still, brought out alive multiple days into the event. and so, you know, a piece of concrete that might have landed sideways and kept that piece of pancake that we see from a distance in the camera. might just be enough for a body to lay sideways on that i-beam just to stay alive. and so, it doesn't take much. even a refrigerator, bathtubs. like you said, those were homes between those floors so everything within that home also serves as a barrier of some type to keeping that roof up above. the floors are really close but there always is still sometimes space to be able to live during that time. and hopefully, the rescuers will be there and the medical team will be right behind it. >> well, you just described a miracle there and we are all hoping for one. joe hernandez, thanks so much for lending your expertise here
