know. as you look at this unique situation, what are the challenges here? >> well, the first challenge without any doubt is to get assets. we know the malaysians and indonesians have already sent planes. get assets on the way. we've seen this in all sorts but we're a lot more experiences in explaining this and a lot more people understand. you're going to see the sort of picture that we saw before of planes flying over water with people looking for wreckage. now in the case of 370, well, they could have will beilooked and wouldn't have found it. in this case if the plane has come out of the sky as we now suspect it has, there will be wreckage. certainly if it has come out of the sky at a very high altitude, 30,000 one would expect there would be quite a lot of wreckage discoverable. i would imagine as day light arrives as the plane goes overhead, you're going to start hearing and seeing the first reports of that.
