what is it like in these moments? it's such a disturbing moment on the one hand to see the bodies in the water to find the debris to know that the plane did go down. but on the other hand there's a closure here that the families of flight 370 don't have. >> i won't call it closure. there's really no such thing, the families tell me. no matter how much time goes past there's no closure. they learn to live with the difference, they have a new identity after the crash, they're the family of an air crash victim and that's with them forever. they're able to go in the work or overdrive mode. search for answers, they want to know what to do they want to know how to honor their loved ones, i can tell you until the last passenger is accounted for and since there is indication that there's a piece of liferaft here a life vest there families will hold out hope until the very end. until once they have the debris field, it's important to work
