also, we have will ripley, another cnn correspondent. he is actually on a ship. he is following the ocean shield out to that search area when we get him live. of course, we ll connect you to him, because he has some interesting things to say. even though the ocean shield is on the way to the search area, there are no guarantees it will find anything. welcome, mary. thank you, carol. as paula said, the black box batteries start to die on saturday. is it worth sending this ship? i didn t hear that. say that again. is it worth it to send this ship to that search area, because we really don t know if the black boxes are there. oh, yes, it is worth it, because they can t just sit and wait. sometimes in investigations, you need a little luck on your side.
