i'm joined by michael chertoff, also by bob haiger, long-time aviation correspondent for nbc. great to have both of you. the fact that there's debris that's scattered around, if you put it together, do you think that's significant? >> yes. they're starting to get a lot of satellite photos of this. i wonder if they're all seeing the same pieces of debris. you've got to the hope it's from this plane. >> of course. and perhaps it is, perhaps it's not. but about that is, we have the currents to worry about. you've got bad weather and wind. it's all about finding the black box which is actually not black but you've got an example of one. >> here's the box. these pieces wouldn't tell you anything about the crash if they find them. if you can trace them back through the currents, this would be the prize, these twos black boxes. this is a flight today recorder. this is the important thing, the pinger, sends out an underwater pink for a month, month and a half after the crash. then you can zero in if you're near the pinger in the water. >> that's the thing, getting near enough to it. t
